Re: [Users] iscsi mpio

[Koch (ovido)]

Hi,

I can give you some information on multipathing on RHEV-H, as I don't
have ovirt-node installed at the moment.

Multipath packages are installed on the hypervisor, but vdsm overwrites
multipath.conf.

To prevent this you have to set the following tags:
# RHEV REVISION 0.7
# RHEV PRIVATE

Search for MPATH_CONF_TAG in multipath.py file to get correct RHEV REVISION 
number.

After changing multipath.conf to fit your needs make it persistent for
reboots:
# persist /etc/multipath.conf


You can check multipath status with:

# multipath -ll
mpathb (b00015521f5d4) dm-0 Intel,Multi-Flex
size=96G features='0' hwhandler='0' wp=rw
|-+- policy='round-robin 0' prio=50 status=active
| `- 0:0:0:1 sdb 8:16 active ready running
mpatha (222140001553601d1) dm-1 Intel,Multi-Flex
size=20G features='0' hwhandler='0' wp=rw
|-+- policy='round-robin 0' prio=50 status=active
| `- 0:0:0:0 sda 8:0  active ready running

I hope this helps.
Don't really know if the tags are the same in oVirt, as I don't have a working 
oVirt setup at the moment.

Re: [Users] What do you want to see in oVirt next?

[Koch (ovido)]

Hi,

First of all thanks for starting this discussion.

My feedback is mainly based on RHEV, as I'm using RHEV in our company
and on customer side. oVirt is cool as I can see what new features next
RHEV version may/will bring and what issues other users have with this
technology.

What I like:
* web based UI
* KVM as it brings the highest virtualization performance on the market
* RHEL/Fedora as a hypervisor for more flexibility
* tags and bookmarks with search filters - great for big installations
* server and desktop virtualization can be done with one gui
* open source of course ;)
* hook scripts - sooo cool!
* rest-api
* user portal - some of our customers use this as a basic cloud tool for
providing vms and self-provisioning features with accounting using
postgresql database

What I would like to see in future release in oVirt and after testing in
RHEV (most of these points are based on customer feedback, too, who
bought RHEV or where we had at least a pre-sales appointment):

* Spice-XPI for Firefox on Windows (and maybe Ubuntu):
I know it's a lot of work to build it for every new firefox version, but
providing it for Firefox LTS would be a really good start. At the moment
Internet Explorer ist required for full use of admin und user portal (or
VNC has to be used).

* ovirt-guest-agents for major Linux distributions:
- openSUSE
- SLES
- Ubuntu
- Debian

* Virtualize ovirt-engine on ovirt hosts
I know that this would require major changes due to how oVirt works
(libvirt and vdsm), but nearly every customers is asking: why can't I
install my hypervisors, create a vm for RHEV manager and configure the
environment then (in the same way as it is possible with VMware)?

* Make ovirt-engine more Enterprise ready
Compared with VMware (sorry for always comparing it with VMware, but
it's the market leader and it has many nice features which would be
great in oVirt/RHEV, too) oVirt required more tasks done on command line
or via API/Shell/GUI as features are missing in the web GUI:

- Deploy network configs on all hosts
When creating a new logical network in a Cluster it has to be created on
all hosts before it can be used. It would be great if this could be done
automatically (except for rhevm/spice/storage-networks where an IP
address of each host is required). The workflow could be:
+ create new logical network
+ click on deploy button
+ create ifcfg-files on hosts
+ make ifcfg-files persistent on ovirt Nodes
+ bring interface up
+ check if interfaces are up
+ make logical network Operational if deployment was successful on all
hosts

- Configure ovirt hosts from GUI
It would be really an improvement if all settings of the TUI (like DNS,
NTP, syslog, kdump, admin and root passwords, hostname,...) could be
configured in ovirt-engine gui, too (in hosts tab). Plus including
changing multipath.conf in Web GUI would be very nice.

- Create host profiles
Storing all configuration settings of the TUI and host tab (without ip
addresses for sure) in a profile would make changes easier and speed up
deployment of new hypervisors. I'm thinking of:
+ create a profile which contains e.g. DNS, NTP and admin passwords
+ link profile to hosts
+ change DNS in profile
+ in hosts tab you can see that there are changes between the profile
and the hosts
+ bring host in maintenance mode
+ sync profile (and maybe reboot host)
When installing new hosts (via CD or PXE) the profile can be used to
automatically configure the host without providing all settings via boot
options + configure all networks, custom multipath.conf,... Host profile
should be used for full RHEL/Fedora hosts as well.

- Update RHEL/Fedora Hypervisors from GUI
It would be nice if Fedora hosts could be updated from the ovirt-engine
GUI like the ovirt Node. Running yum check-update on host and displaying
notice if there are updates available.

- Implement resource pools
At the moment only Quotas are available (which is great, btw), but in
some cases it's necessary to implement resource pools. E.g. Limit CPU,
Memory and Network for group of test vms, but give full resources to
production vms. This could be done with cgroups.

- Clone vms
I'm missing the possibility of cloning vms without creating a template. 

- Resize disk in GUI
Increasing the size of a disk would help a lot. At the moment I create
new disks and put it into volume group on vm, but resizing would be
nicer in some cases and will reduce the number of disks.

- Upload ISOs within the GUI to ISO domain

- Integrate virt-v2v into oVirt GUI
It would be cool if VMs could be Migrated from other systems within the
GUI using virt-v2v as a backend.

- Edit settings of vms before importing them
Most the of the settings like disk type (IDE/VirtIO), nic but also vm
type (server/desktop) and access protocol (Spice/VNC) can't be edited
withing oVirt/RHEVM GUI before importing them. These settings can only
be changed by editing the xml directly. Disk type and nic is risky of
course, but working for most Linux distr

Re: [Users] What do you want to see in oVirt next?

[Koch (ovido)]

Hi Marcelo,

Regarding your 6. point:

I wrote a plugin for Icinga/Nagios to check RHEV 3.0 environment using
REST-API. At the moment there are 2 bugs (1 fixed in latest svn trunk, 1
open) to fully work with RHEV 3.1 (and properly oVirt 3.1):

https://labs.ovido.at/monitoring/wiki/check_rhev3

It would be great if you could test it with oVirt and give me some
feedback :)

Re: [Users] Destktop VM to Server VM ?

[Koch (ovido)]

Hi,

You can edit the .ovf file of your vm on the export domain.

Change  to:
0 ... Desktop
1 ... Server

Then you can import your server/desktop vm using the engine GUI...

Re: [Users] Can I move local_cluster in all-in-one setup?

[Koch (ovido)]

Hi Gianluca,

You could try the following:

- Create new datacenter and cluster
- Set VLAN for ovirtmgmt network in new DC
- Delete localhost from Default cluster
- Configure VLAN tagging on host manually
- Join localhost to new cluster using oVirt Admin Portal

Before joining localhost to the new cluster, comment out rebooting in
vds_bootstrap_complete.py:

$ vi /usr/share/vdsm-bootstrap/vds_bootstrap_complete.py
#deployUtil.reboot()

Re: [Users] Can I move local_cluster in all-in-one setup?

[Koch (ovido)]

Hi Gianluca,

I just successfully installed RHEV 3.1 all-in-one with VLAN tagging on
rhevm (ovirtmgmt) network - steps should be the same on oVirt:

1. Configure VLAN on host (ifcfg-eth0.)
2. Install oVirt environment with all-in-one setup
3. Login to webadmin
4. Set local storage to maintenance
5. Force remove datacenter
6. Create new datacenter (new name, type: local)
7. Create new cluster (new name)
8. Edit ovirtmgmt network on new datacenter (set VLAN)
9. Bring host to maintenance
10. Edit host
10.1 Change datacenter to new datacenter
10.2 Change cluster to new cluster
11. Create new local storage
12. Verify that datacenter and host are online and that network is in
sync including VLAN
13. Attach ISO domain (I used the one created with rhevm-setup)
14. Create vm

I hope this will help you with oVirt.
Maybe you should cleanup your all-in-one setup and recreate it using the
above steps.

Re: [Users] Can I move local_cluster in all-in-one setup?

[Koch (ovido)]

Can you have a look at your network setup dialog in ovirt webadmin if
the network is in sync?

If not, please do a resync.


You're right - the ip address should be on interface ovirtmgmt, not on
em3.

[Users] UI Plugins in nightly?

[Koch (ovido)]

Hi,

I installed oVirt engine on Fedora 18 with latest nightly RPMs and
wanted to test the UI plugins, but it seems as this feature is still not
available in nightly.

According to Oved blog post
(http://ovedou.blogspot.co.at/2012/12/ovirt-foreman-ui-plugin.html)
custom plugins should be put into: /usr/share/ovirt-engine/ui-plugins
UI plugins page on oVirt webpage
(http://www.ovirt.org/Features/UIPlugins)
proposed /usr/libexec/ovirt/webadmin/extensions as the folder for UI
plugins.
But neither of these folder does exist in my setup.

So I wanted to know if UI plugins are still not packaged and if they
will be included in final oVirt 3.2?

Thanks a lot.

I'll try if this works. Thanks.

As I read in your blog that - at the time you created the foreman
extension - UI plugins were not included in oVirt RPM packages I thought
it's still missing as I don't have this folder on my system.

Hi,

You can change boot options using the following steps:
1. Boot from CD
2. Press "Tab" when you see "Start Ovirt Node"
3. Change "root=live:CDLABEL=ovirt-node-iso" to "root=live:/dev/sr0"

Hi,

You can find a documentation on how to use the python sdk here:

Should be the same for oVirt...

Re: [Users] How to import KVM machines into oVirt iSCSI

[Koch (ovido)]

Hi,

The following command migrates a KVM vm named "test-rhel6" to your
export domain "ovirt-engine:/data/nfs/export" with qcow2, thin
provisioned disk and ovirtmgmt-network from KVM host "kvm-host":

# virt-v2v -i libvirt -ic qemu+ssh://root@kvm-host/system -o rhev -os
ovirt-engine:/data/nfs/export -of qcow2 -oa sparse -n ovirtmgmt
test-rhel6

See "virt-v2v --help" for details...

You can also create a profile in /etc/virt-v2v.conf to avoid command
line arguments for virt-v2v...

For migration you need an export domain which must be NFS (not iSCSI).

So the migration steps are:
1. create export domain
2. activate export domain on datacenter
3. install virt-v2v on ovirt engine host
4. migrate host to export domain
5. import vm from export domain

[Users] UI Plugin iframe dialogs

[Koch (ovido)]

Hi,

I'm still working on my Nagios integration plugin and came across a
limitation of the UI plugin framework caused by iframes.

UI framework creates an iframe for each plugin, so the plugin code is
separated from the main oVirt webadmin code (and other plugins). When
creating a new (big) jQuery dialog in an sub tab-iframe (sub tab of
selected vm or host) it can't be displayed without scrolling in the sub
tab or resizing the sub tab (that's clear as it's displayed in an too
small iframe).

So it would be great if it would be possible to display dialogs in the
middle of the main windows and overlap the iframe (don't know if this is
possible). In short terms I want to create a dialog which behaves like
e.g. the "Setup Host Networks" or "Add Permission to User" dialogs ->
click on a link in the plugin iframe and dialog opens in the middle of
the website not the middle of the iframe.

What I found out so far is that:
1. I must be aware of the same origin policy (that's no problem)
2. I need to put my jQuery-dialog-code in the main oVirt windows and
then I can call it from within the iframe (that's my problem)

So my questions are:
Is it possible to place code outside of the iframe?
If not - are there plans to allow this in future releases?
Or maybe is there a workaround?


Thanks a lot,
René

Hi,

You can simply bypass your with "ProxyPass ... !":

In my setup I bypass /ovirt-monitoring, which resides in /data/www:

# vi ovirt-engine.conf

ProxyPass /ovirt-monitoring !
ProxyPass / ajp://localhost:8702/ retry=5 timeout=3600

# vi ovirt-monitoring.conf
Alias /ovirt-monitoring /data/www/ovirt-monitoring

[Users] oVirt 3.2 and Solaris 10 guests

[Koch (ovido)]

Hi,

I've a strange network issue with Solaris 10 x86 guests on oVirt 3.2
(beta) with an CentOS 6.3 hypervisor (using dreyou's repository for VDSM
packages).

My host configuration is the following:
Operating system: Other
Network interface type: rtl8139
Network Name: ovirtmgmt
Disk interface: IDE

Disk is working fine and the network interface is detected by Solaris 10
guest, as I can see a rtls0 interface with "ifconfig -a" and Solaris
installer also detects this interface.

But when I try to send packages over this interface they never reach a
target - e.g. ping the gateway and "arp -an" doesn't show it's MAC
address. On the hypervisor I can see vnet(x) interface is on ovirtmgmt
bridge. Network traffic is working fine for all other VMs (RHEL 6 and
Fedora 18) on ovirtmgmt bridge.

Btw, when creating a Solaris 10 guest on RHEV 3.1 with RHEL 6.3
hypervisor the exactly same issue occurs - network interface is detected
but no traffic passes this interface.

On a plain KVM-Host (RHEL 6.3) I can create a Solaris 10 host with
virt-manager using rtl8139 Virtual Network Interface Device model on a
bridge (network setup is nearly the same as for oVirt and RHEV). On this
RHEL 6.3 KVM-host network is working fine for Solaris guests.

In the process list (ps -ef) the settings for oVirt and RHEL-KVM seem
the be nearly the same (different fd's and option bootindex=3 is missing
on KVM):

oVirt 3.2:
-netdev tap,fd=25,id=hostnet0 -device
rtl8139,netdev=hostnet0,id=net0,mac=00:1a:4a:00:64:9e,bus=pci.0,addr=0x3,bootindex=3
 

RHEL 6.3 KVM: 
-netdev tap,fd=36,id=hostnet0 -device
rtl8139,netdev=hostnet0,id=net0,mac=52:54:00:8e:3a:57,bus=pci.0,addr=0x3 

KVM-Version is exactly the same on CentOS-oVirt-Hypervisor as on RHEL
KVM-host:
# rpm -qa | grep kvm
qemu-kvm-rhev-tools-0.12.1.2-2.295.el6.10.x86_64
qemu-kvm-rhev-0.12.1.2-2.295.el6.10.x86_64

Do you have any clue why Solaris networking isn't working on oVirt but
on RHEL-KVM it is?

I didn't try Fedora 18 or oVirt Node as a hypervisor yet - don't think
that there will be a difference.

Thanks a lot for your feedback.

Same for me - e1000 aren't working with oVirt 3.2 and Solaris 10, too.

[Users] Introducing oVirt Monitoring UI-Plugin

[Koch (ovido)]

I'm happy to announce oVirt Monitoring UI-Plugin, which allows the
integration of a Nagios or Icinga monitoring solution into oVirt 3.2
webadmin. With this plugin you can access detailed service check results
and information including performance graphs within oVirt webadmin for
hosts and virtual machines.

We look forward to extend this plugin with more Nagios/Icinga features
like acknowledgments, comments or service rescheduling, permissions,
dashboards, check_mk-integration for virtual machine monitoring and many
more.

For more information about this project and screenshots please visit ​
https://labs.ovido.at/monitoring/wiki/ovirt-monitoring-ui-plugin


The download location is
  * ​
https://labs.ovido.at/monitoring/wiki/ovirt-monitoring-ui-plugin
%3Adownload

Please note that this first release is an early development version with
some minor CSS bugs on some browsers.

If you have any questions or ideas, please drop me an email: ​
r.k...@ovido.at.

Thank you for using oVirt Monitoring UI-Plugin.

That was my plan - the plugin should fit as good as possible into oVirt.

Sounds really great.
I use Perl Template Toolkit and jQuery at the moment, but think that
Template Toolkit isn't really necessary as most of the HTML could be
done with plain HTML and jQuery as well.

I'll skip the api.ready call - thanks for the information.

Yes of course - thanks.

Re: [Users] Packet loss to guests

[Koch (ovido)]

Hi Neil,

I had a similar issue with my oVirt environment with some vms.
The issue on my side was oVirt and RHEV environment in the same subnet
and conflicting MAC addresses on some vms (as both use the same MAC
range and I didn't change this with engine-config).

So can you check if this MAC our your vm is in use by an other host/vm
(maybe from a KVM installation)?

Re: [Users] Packet loss to guests

[Koch (ovido)]

Hi,

If you don't have another oVirt / RHEL KVM host in the same network than
MACs want be an issue. So it's totally save to have oVirt in the same
network as all other systems.

I see in your email that you use bonding mode 2. This shouldn't cause
issues with switches, but I think I had an issue with RHEV (bond 2) and
a Cisco switch once on customer side - please don't ask me for details
on what their network admins changed to make this setup work.

Can you try bonding mode 0 (active-backup) and check if you still have
packet loss?

Re: [Users] Possible migration from oVirt to RHEV?

[Koch (ovido)]

Hi,

The reason is most likely to have a stable production environment with
support and to have oVirt as a testing environment.

For the migration process:
- Implement your RHEV environment
- Create an export domain within RHEV, but don't attach it to your RHEV
datacenter
- Attach your export domain to oVirt datacenter
- Export your vms
- Detach export domain on oVirt and attach it in RHEV
- Import your vms

Did move a few vms from oVirt to RHEV and it worked fine.

Just make sure that you change to MAC range as oVirt and RHEV use the
same range and this will cause problems when you have vms with
conflicting MAC addresses.

You need a remote management interface (IPMI, ILO,...) in your servers
and an user which has permissions to power off/on/reset the server using
this interface. The IP address of this interface must be accessible from
all hosts in your cluster.

When editing your host preferences you see all supported devices under
"Power Management" - "Type". On most systems (IBM, hp, Supermicro,...)
ipmilan will work.

Btw, does anyone know if it's possible to add custom fencing scripts for
power management?

Re: [Users] Fast way to see all snapshots on my infra?

[Koch (ovido)]

Hi Gianluca,

You can try something like this (dirty) command:

URL='https://localhost/api'; USER='admin@internal';
cp /dev/null /tmp/ovirt-snapshots; echo -e "list vms\nexit"
> /tmp/ovirt-vms; for VM in `ovirt-shell -l ${URL} -u ${USER} -c -I
-f /tmp/ovirt-vms | grep name | tr -s ' ' ' ' | cut -d' ' -f3`; do echo
"list snapshots --vm-identifier ${VM} --show-all"
>> /tmp/ovirt-snapshots; done; echo "exit" >> /tmp/ovirt-snapshots;
ovirt-shell -l ${URL} -u ${USER} -c -I -f /tmp/ovirt-snapshots

Re: [Users] User Portal

[Koch (ovido)]

Hi,

If you login with PowerUser permission you have 2 tabs (Basic and
Extended) where Basic is the UserPortal and Extended the
PowerUserPortal.
So you can switch between these 2 views.


Btw, in RHEV (3.0 and 3.1) I see a (for me) strange behaviour and
haven't tested if this is the same in oVirt.
When installing RHEV a "Default" datacenter is created and everyone has
permission on template "blank". As long as I don't remove permissions on
"blank" template user with role "UserRole" start in PowerUserPortal
(Extended view) instead of UserPortal (Basic view) - without permission
on template "blank" they can't switch between these 2 views/portals
(which is the expected situation - users with UserPortal permission
shouldn't be aware of the PowerUserPortal).
Is this bug or intended?


Regards,
René

Re: [Users] Templates and originating VM relationship

[Koch (ovido)]

Hi Gianluca,

@oVirt-team: please correct me if I misunderstood something on the
template-concept...

Unlike Vmware (which converts a vm into a template) RHEV/oVirt is
copying the vm into a template.

So you can remove or edit your original vm without having an impact on
your template.

More important is the template provisioning method when creating vms
from your template. If you choose Thin, only changes between your
template and your vm are written to your vms disk file, where clone
creates a clone of your template's disk. Template thin provisioning
saves disk space, but you can't delete the template as long as you don't
delete all vms linked to this template.

The name of your disk is just a name (and it seems that it doesn't have
to be unique) - important is the ID, which is used by oVirt internally.


Regards,
René

I didn't had issues when creating templates from vms without snapshots
and reusing the vm again.

I think it's because of sealing/sysprep.

Let's assume you create a template of a windows vm, I would do the
following steps:
1. Install all apps and settings in your vm
2. Take a snapshot of this vm
3. sysprep your vm
4. Create a template
5. Revert to previous snapshot when reusing your vm, as otherwise
sysprep would start (and you don't want it for your master-image).

I can confirm that it's possible to use oVirt/RHEV with Samba 4 - tested
RHEV 3.0/3.1 with Univention Corporate Server which is a SBS server on
Linux base with Samba 4.

For RHEV it's  not recommended to use Administrator for Active Directory
even if it works mostly. Did it several times where it worked fine with
Microsoft Active Directory - not sure if I faced isses with
Administrator user.
But in general it's better to have an other user with admin permissions,
as this will always work (if you set up DNS correctly).

René

I'll try it with 3.3 nightly and will let you know.
Can I virtualize an oVirt 3.3 hypervisor on an oVirt 3.2 host based on
CentOS 6.4 (does RHEL 6.4/CentOS 6.4 support nested KVM or do I have to
use Fedora 18?) as I'm short with hardware at the moment?

[Users] DNS for IPA in oVirt

[Koch (ovido)]

Hi list,

I don't want to ask my question in the mail thread of Eduardo to avoid
mixing topics.

Can you give me more detailed information on how oVirt is using DNS
internally and how IPA users can work in the following scenario:

# engine-manage-domains -action=list
Domain: ovido.at
User name: ad...@ovido.at
Manage Domains completed successfully

# cat /etc/hosts | grep engine
10.0.100.195 ovirt-engine.lab.ovido.at

# ip a
2: eth0:  mtu 1500 qdisc pfifo_fast
state UP qlen 1000
link/ether 00:1a:4a:00:64:14 brd ff:ff:ff:ff:ff:ff
inet 10.0.100.195/24 brd 10.0.100.255 scope global eth0

# host ovirt-engine.lab.ovido.at
ovirt-engine.lab.ovido.at has address 10.0.100.24

# host 10.0.100.24
24.100.0.10.in-addr.arpa domain name pointer ovirt-engine.lab.ovido.at.

So in my case I have correct DNS settings (forward and reverse), but my
ovirt-engine host has a totally different IP address.

I didn't test SSO with Kerberos in user portal (maybe this want work),
but authentication with IPA user in user portal and admin portal is
working fine even with these totally wrong DNS configuration.

René

It seems that this banner does reflect the oVirt/RHEV major version.
Connecting to RHEV 3.1 with ovirt-shell (from oVirt 3.2 package) gives
me the following banner:

 ==
 >>> connected to oVirt manager 3.1.0.0 <<<
 ==

oVirt 3.2.1 says "connected to oVirt manager 3.2.0.0"

Sorry, can't give you detailed information on how to create a Samba 4
directory (use UCS appliance) - there is plenty of documentation in the
internet on how to do that.

To connect oVirt to your existing Samba domain, use the DNS server from
your samba server on your ovirt-engine host (don't do replication to
external bind servers, as this causes some issues). You have to make
sure, that you have valid forward (A) and reverse (PTR) DNS entries for
your ovirt-engine host and SRV records for LDAP, Kerberos,... (but these
should be created by default and are required for your Windows clients,
too).

You can join your Samba4 domain with "engine-manage-domains
-provider=ActiveDirectory ..."


I hope this helps you a bit.

Re: [Users] DNS for IPA in oVirt

[Koch (ovido)]

Hi,

Thanks a lot for your detailed explanation.
That mean that I don't need DNS entries (forward and reverse) for oVirt
engine anymore, only SRV records for the directory service (for sure)?
So using IP or /etc/hosts is sufficient.

[Users] oVirt Presentations

[Koch (ovido)]

Hello list,

I just want to inform you that I'll be talking about RHEV and oVirt on 2
(maybe 3) events in Austria and Germany in the next weeks (45min
presentation slots).


The first one is at the Open Source Data Center Conference in Nuremberg,
Germany which takes place from April, 17th to April, 18th:
http://www.netways.de/en/osdc/osdc2013/

Details on my presentation (presentation language is German):
http://www.netways.de/index.php?id=3732&L=1
Main focus will be Red Hat Enterprise Virtualization, but will also talk
about oVirt.


The second event is at the Graz Linux Days in Austria on April, 20th:
http://www.linuxtage.at/ (Sorry, there's no English version available)

Details on my presentation (in German):
http://glt13-programm.linuxtage.at/events/174.de.html
As this event is a non-profit community event I'll be focusing on oVirt,
but will also talk about differences to RHEV.


Eventually I'll be talking about oVirt on the Linux Weeks in Vienna,
Austria, too. This event is from May, 2nd to May, 4th:
http://www.linuxwochen.at/
At the moment the call for papers is still running...


If there's someone from Germany or Austria on this list and attends on
one of these events please let me know :)

Is this an Intel modular server, btw?
If yes - create a Fibre channel datacenter and add the storage as FC
LUNs. I can also send you a working multipath.conf for Intel Modular if
required...

You can contact me if you have questions regarding these server - I
use(d) this system in the company I worked before and on customer side.

Attached is a working multipath.conf for RHEV-H 3.0.
You need a working multipath.conf file if you have redundant storage
controllers.

Find out the wwids of your devices and add them to your
blacklist_exceptions section.

# multipath -ll
mpathb (b00015521f5d4) dm-0 Intel,Multi-Flex
size=96G features='0' hwhandler='0' wp=rw
|-+- policy='round-robin 0' prio=50 status=active

size=20G features='0' hwhandler='0' wp=rw
|-+- policy='round-robin 0' prio=50 status=active
| `- 0:0:0:0 sda 8:0  active ready running

Don't forget to persist /etc/multipath.conf if you're using ovirt-node!
With this config you don't need the Intel multipath drivers, btw.

Please let me know if you have further questions.

Re: [Users] Ipa server inside ovirt itself. ..

[Koch (ovido)]

Hi,

I don't see big issues, as you can always log into oVirt as
admin@internal and start/stop/reset/... your IPA-vm.

If your other vms use IPA for authentication (e.g. for service SSH) you
can configure sssd for caching credentials if your IPA server is
unavailable. ipa-client-install is doing it automatically, btw.

René

Re: [Users] High Availability OVirt

[Koch (ovido)]

Hi,

You can use a cluster software like pacemaker or RH Cluster to make your
ovirt-engine high available.

I personally recommend to virtualise it on a KVM host, as keeping
virtual machines high available is much easier then making all services
ovirt-engine need high available (but it's possible for sure).

So what happens when your engine hosts goes down:
- You can't login into webadmin and user portals
- high availability and live migration features of your virtual machines
aren't working
- You can't start/deploy new virtual machines
- Your hosts and virtual machines that are already running stay up of
course

As clustering brings in more complexity I would use a server with RAID,
redundant power supplies and redundant network interfaces (bonding) for
ovirt-engine instead of clustering. Only when using desktop
virtualization where availabilty of the user portal is really important
I would cluster ovirt-engine.
(But this is just my personal opinion)



Regards,
René

Can you attach vdsm.log of your hypervisor?

I guess there will be error messages like missing logical volumes or
libvirt getcapability check issues. Have seen these and host-behavior
was the same as in your case. I solved it by changing storage to local
NFS. Didn't had enough time to report bugs, yet - sorry for this.

[Users] NFS domain and LVM

[Koch (ovido)]

Hi,

I just rebooted my NFS server which hosts a ISO domain which is used by
RHEV 3.1 and oVirt 3.2. In both environments the ISO domain became
inactive and I tried to activate it again.
In RHEV this worked fine, but in oVirt it didn't.

Just for your information: both - RHEV and oVirt use "Local on host" as
datacenter storage type.
I normally use a local NFS server and mount the share locally (dc with
storage type NFS) as "Local on host" is making troubles in most of my
setups (in both - oVirt and RHEV) and the issues are mainly missing
(sometimes lost) volume groups.
As my oVirt 3.2 setup is a testing environment and my test vms are still
running, I'll keep it in this state for finding a solution for this. As
said, have seen issues like this more then one time before, so maybe
this is a bug and need some attention (can also open a bug report if
needed).


vdsm.log is telling me that the storage domain doesn't exist (as
complained by vdsm daemon):

Re: [Users] Vlan interface on top of bonding

[Koch (ovido)]

Hi,

first of all welcome to the oVirt project.

Did you configure vlan tagging for your ovirtmgmt network?
If you're using vlan tagging on (bonded) interfaces in oVirt you have to
add a vlan tag to all logical networks - can't mix tagged and untagged
logical networks.

e.g (same for bonds as well):
Name - VLAN- Network Name
eth0 - eth0.10 - ovirtmgmt
   eth0.11 - lan1
   eth0.12 - lan2

Hope this helps.

Re: [Users] Engine-config -s small problem

[Koch (ovido)]

Hi,

No, oVirt isn't aware of config changes - it's by design, not a bug.

You always have to restart engine when changing values (as noted in
engine-config help text).

# engine-config -h

### 2. In order for your change(s) to take effect,
###restart the oVirt engine service (using: 'service ovirt-engine
restart').

If you can specify in more detail what you want to do I can maybe help
you getting the right API calls/queries.

To my understanding you want to list all hypervisors (and stats, too?)
grouped by cluster name, right?
cluster01:
- host01
- host02
cluster02:
- host03
- host04

And you also want to display storage stats for each storage domain.
Should they also be grouped in any way or is it just displaying stats?

Btw, do you use one of the SDKs (Python/Java), ovirt-shell or are you
connecting to REST-API directly (using curl, perl LWP::UserAgent,...)?

It's one of the features in the latest version (1.2):

 -o, --cookie
Use cookie based authenticated sessions (requires RHEV >= 3.1)


I implemented it in the following way:
- Plugin checks if file with session cookie exists (per default
in /var/tmp)
- If not: login with username and password (that's why you need to
specify auth pair or authfile) and fetch JSESSIONID
-- Writes ID into session cookie file
- If cookie file is found: login using JSESSIONID and ignore username
and password. So you can change username/password and login will still
work.
- If login using session ID fails and cookie file exists, it will be
deleted and a login with username and password is tried the next time
the plugin is executed

If you start the script with -vvv you can see if login is down with auth
session or with username/password...

I didn't test it with oVirt 3.2 (yet), but works fine in RHEV 3.1.

René

Re: [Users] Active Directory Groups

[Koch (ovido)]

Hi,

I also had a problem with '#' in an customer project with RHEV 3.0, but
we also had issues with a broken active directory replication. White
spaces aren't a problem in groups.

I can't tell if groups with '#' are working, as I told them to not use
special characters in group names and to fix their replication. Now
everything is working fine, but don't know if they created new groups
for RHEV or if it was just the replication.


Regards,
René

Hi,

I started writing a Perl (prototype) script a year ago to make the
process of "updating" pool vms a little bit easier. What this script
does (should do) is:
- stop all vms which belong to this pool
- detach vms from pool
- delete vms
- delete pool
- delete template
- create new template from master vm
- create new pool
- add users/groups to pool

All these tasks are possible with the Python/JAVA SDKs and ovirt-shell,
too.
Just make sure no other vms/pools uses this template with thin
provisioned allocation policy. And don't forget error handling...

René

Are there plans to provide packages for Windows or various Linux
distributions in oVirt repositories as long as they aren't available in
official distro repos?

Another little bit off-topic question: what are the criteria for an
operating system to be listed as an operating system when creating new
servers/desktops? At the moment the same os'es are listed as in RHEV.
In my opinion either all distributions which are fully tested (working
IDE/VirtIO disks, e1000/rtl/VirtIO nics, maybe guest agent available...)
should be listed here - in a similar way as you can find it in
virt-manager...

For me it's clear that I can run e.g. Debian vms on oVirt and I have to
choose Other Linux for debian. But having e.g. Debian, Ubuntu, openSUSE
in the list of operating systems and their icons in user and self
provisioning portal would look much nicer.

Last, it would be great to have a matrix of operating systems in oVirt
wiki to provide an overview which operating systems are working and
where you can find guest agent packages - as available for e.g. VMware
and KVM. I think there are a lot of users tried out different operating
systems and are willing to update the support matrix...
I think this would help a lot to find the right settings for operating
systems. e.g. for Fedora 18 I can/should choose VirtIO disks and nics,
but for Solaris 10/11 only IDE disks are working and network isn't
working (none of the 3 types).

What do you think?

This was required for RHEV 3.0, which was the version I initially wrote
the plugin for.

For newer versions (>= 3.1) of oVirt and RHEV you only need the
following permissions (create new role for it, or is there a role
available in oVirt > 3.2.1?):
Account Type: Admin
System - Configure System - Login Permissions

This allows a user to connect to REST-API (and Administrator Portal) and
read everything, but doesn't allow any changes (=> read only).

I'll update the documentation.
Thanks for reporting this documentation bug.

René

You could either create apache vhosts for your different services or
just edit /etc/httpd/conf.d/ovirt-engine.conf and exclude your BackupPC
url from beeing passed to proxy url (add before ProxyPass option).
e.g (don't know exact BackupPC url, so you have to adapt):
ProxyPass /backuppc !
ProxyPass / ajp://localhost:8702/ retry=5 timeout=3600

Hope this helps.

In my oVirt 3.2.1 setup there's no such predefined role.
Was this maybe added later?

Hi,

You need a host to initialize the storage.
The host you have to choose with "Use Host" initially creates the data
structure,... on the storage.

Afterwards all host in your cluster will mount the storage and write
data for their vms. There's no one-node bottleneck.

So you will have vm storage on node01, node02 and on your NFS storage,
right?

I would recommend to use LVM and add new disks into your logical
volume...

Each local storage host requires it's own datacenter and you can't mix a
datacenter with local storage with NFS storage.

What I would do in your case:
1. Use CentOS/Fedora hosts instead of oVirt-Node.
2. Configure NFS-Server on each Node.
3. Have 1 datacenter with 1 cluster and 2 nodes with storage type NFS.
4. Add 3 storage data domains (NFS-Share of each host and NFS-Share of
your main NFS server).
5. Bind vms with local NFS server to local host...

Or with GlusterFS:
1. Use CentOS/Fedora hosts instead of oVirt-Node.
2. Configure replicated GlusterFS volume over your 2 nodes
3. Have 1 datacenter with 1 cluster and 2 nodes with storage type NFS
4. Add 2 storage data domains (NFS-Share of GlusterFS volume and
NFS-Share of your main NFS server).

Disadvantage of GlusterFS with NFS: one of your 2 nodes is exporting the
NFS share and if this node is down your storage domain is down and you
have to manually fix the mount.

MD-Raid or DRBD,... isn't possible, (yet?).
You could try GlusterFS 3.4 (replicated volume over your 2 nodes)...

Hope this helps.

Afaik if you add another local data store the existing one will become
inaccessible from within oVirt. If I remember correctly a new datacenter
and new storage domain will be created and the original one will be
dropped from oVirt, but still contains data.

Re: [Users] Nic names : always start by eth0

Hi,

The easiest way is to remove 70-persistent-net.rules in your master-vm,
remove HWADDR-strings from ifcfg-eth* friles, shut it down and create
the template.
Btw, also remove your ssh-keys in your template to create unique ones
for each vm...

All you have to do is to change the URL of ovirt.repo to point to your
repo-server...

Btw, you can also have a look at Spacewalk, but if you only want a
repo-server it may be an overkill: https://fedorahosted.org/spacewalk/

Hi,

I would solve this in the following way:

1. configure 2 logical networks with vlans
e.g. lan1 (vlan id 100, ip network 10.0.0.0/24), lan2 (vlan id 200, ip
network 10.0.1.0/24)
2. assign vnics of vms to corresponding logical network
3. create firewall rules on firewall to allow/disallow communication (fw
must be in both vlans)

Hope this helps.

René

Re: [Users] Automating the manual labour between us admins and our potential customers (orderportal)

[Koch (ovido)]

Hi Karli,

Thanks a lot for sharing the code of your orderportal! I think this
portal is really useful for providing a easier method to create/order
new virtual machines as the (extended) user portal already does.

I'll try it out and maybe will have some questions.
First question right now: is and if yes how is your software licensed?

[Users] oVirt and Infiniband

[Koch (ovido)]

Hi,

Does anyone have oVirt (or a plain KVM hypervisor) running on Infiniband
where the virtual machines are bridged to an Infiniband interface (with
EoIB kernel module)?

I'm having issues in such a setup where vms can't communicate over this
bridge...

Hi,

Should it be possible to disable SSO in 1.0.6 already (cause these options are 
unrecognized)?

r.koch@pc-ovido02:~/tmp/ovirt-guest-agent-1.0.6$ ./configure --without-sso 
--without-gdm --without-kdm
configure: WARNING: unrecognized options: --without-sso, --without-gdm, 
--without-kdm


It's working fine with guest-agent from GIT (tested compiling on Debian but not 
on FreeBSD):

# git clone http://gerrit.ovirt.org/p/ovirt-guest-agent.git
# ./autogen.sh
# ./configure --prefix=/usr --without-sso
# make install

[Users] Please test check_rhev3 1.3 alpha

[Koch (ovido)]

Hi,

As discussed in previous thread I improved the authentication of my
Nagios plugin to use auth cookies per default and fall back to username
and password authentication on failure.
Here's a documentation how authentication is handled now:
https://github.com/ovido/check_rhev3/issues/1

You can download the alpha version from:
https://github.com/ovido/check_rhev3/blob/master/plugin-dir/check_rhev3.pl

Please note that this is an early development version not intended to
use in production setups yet (requires some testing).
If you test it, please give me some feedback if the authentication is
working as expected. This means, that no "user@domain logged in"
messages appear in oVirt engine (if using oVirt >= 3.1) when Nagios is
checking oVirt environment.
Thanks a lot for testing and your feedback!


There's one known issue - if REST-API returns an error the plugin also
falls back to username and password. This happens e.g. when querying
interface statistics for vlan tagged interfaces on RHEV 3.2, which
returns "Operation Failed" (see
https://bugzilla.redhat.com/show_bug.cgi?id=993123).
Don't have a solution for this right now...

René

[Users] Linux sysprep

[Koch (ovido)]

Hi,

Has anyone an idea what's the easiest way to sysprep Linux (CentOS 6 and
RHEL 6) machines?

The use case is the following: I want to create a lot of virtual
machines (e.g. 100) by cloning from one template.
So I create a master vm, create a template and a pool with 100 vms
assigned to it and set all 100 vms to prestarted.

The problem is now, that when I run "sys-unconfig" before creating the
template, which does a "touch /.unconfigured" I have to go through the
sysconfig-tui and set a new root password for all 100 hosts.

So what I'm looking for is a script like the sysprep tool for windows
which sets parameters for me automatically.
I only need to change:
* Hostname + set DHCP_HOSTNAME in ifcfg-eth0 (Hostname == Pool-VM-Name)
for some dhcp/ddns magic :)
* Clear udev network-rules
* remove SSH-Keys
* Remove RHN ID and join Satellite/Spacewalk-server
* root-password,... should stay the same

My first question is: does oVirt provide such a functionality for Linux
guest out-of-the-box? I couldn't find one.


I think I could solve this with virt-sysprep and virt-file, but I'm
unsure if I can use it with oVirt (or only with plain libvirt):
http://libguestfs.org/virt-sysprep.1.html
http://libguestfs.org/virt-edit.1.html

For this tools it's required that the vm is not running, as it changes
files on the disk. If I'm using a before-vm-start hook, it should be
save to access the disk and change content with virt-sysprep/virt-file,
right?
But do I have access to the disk in a before-vm-start hook?
If using NFS storage I should be able to access all disks on the
NFS-share, but for iSCSI/FC-LUNS - are they available on the hypervisor
in this stage?


Another option would be to write a custom script which is started during
boot and disables itself after successful run (in the same way as
firstboot - I already have such a script for RHN Satellite/Spacewalk
joins). The problem here is: How do I get the (oVirt) name of this vm
(would need something like virt-whoami :) )? Is the (internal oVirt) ID
of this vm stored somewhere in the filesystem of this vm? I don't think
so


Thanks a lot for suggestions,
René

Great that you choose this flow - I think it's the one which is the most

I think the primary card has to be enabled whenever power management is
enabled, but power management should stay disabled per default.

If you keep with the concept of having a primary and secondary card you
shouldn't be able to remove one of these 2 cards - only
enabled/disable/edit it.

One thing that keeps in mind for a future improvement (somewhere after >
3.3) would be a power management template.
When having a bigger setup (assuming 20 hosts from the same manufacturer
and therefor with the same remote management cards) you have to set
address, username, password, type, (maybe port) and (maybe options) 20
times (with 2 cards 40 times). But it would be much easier if I create a
power management template and set all parameters except address, choose
this template in power management tab of each host and set the address
of the card there.
But as said - would be nice to have in the future.

René

Mellanox support team found the issue:
Daemon openibd requires write access to libvirt which is restricted by
oVirt per default.

When changing auth_unix_rw to "none" networking of the vms is working fine
over the inifinband network.

So my question is now:
I think there's a good reason why write access to libvirt is restricted.
In my particular setup no one will do a virsh start/stop/whatever so
from a user point I can live with an open libvirt.

But are there any troubles I can run into from oVirt side with
auth_unix_rw="none" beside users doing evil virsh stuff?

Today I tested it and ran into a first issue which I didn't investigate
so far (will do this week):
- Started vm from oVirt on node
- Changed auth_unix_rw to "none"
- Restarted libvirt on node
- VM was running according to "virsh list"
- VM was stopped in oVirt
- Started vm in oVirt on another node
- vm was running twice
Will have a look at the logs what append exactly this vm...

Thanks a lot, Yuriy.
That's an interesting solution you came up with. Although I'm unsure if
I like to use bios fields for this. Beside this "little bios hack"
you're doing the same as with payloads except you're properly using
dmidecode in your init-script to get the vm name instead of mounting a
floppy and reading content of a file.

I see - so only via REST-API really means only with REST-API ;)
I'll add the payload via put request - thanks a lot!

Absolutely agree that this would be the best solution, but unfortunately
there's no config option for openibd to use credentials when connecting
to libvirt :(

Hm, for some strange reason I can PUT the payloads XML to a specific vm
without any errors using REST-API, but it seems to never really update
the vm definition (when testing with GET payloads is missing again and
no cd in my vm). PUT for e.g. usb definitions is working fine (system is
oVirt 3.2).

Anyway, I don't have enough time at the moment to investigate this
further, so I use Yuriy's script (thanks!) and add the hostname via SKU
number. But will maybe play with vm payloads later again.

If anyone is interested in the scripts, feel free to use them:
https://github.com/ovido/ovirt-stuff/tree/master/sysprep_linux
(please note that these will only work for RHEL/CentOS/Fedora/other
clones)

Hm, this makes sense.
I managed now to create a payload cd and can also access it from my vm
as expected.

Thanks all for your help,

In my opinion this is the better solution but still not enough. Let me 
explain why:

There are 4 reasons (or did I forgot one?) why I want to change the network 
configuration:
1. Add new logical networks
2. Remove logical networks
3. Change ip addresses of 1 (or more) logical networks
4. Configure/change bonding options

Ad 1 and 2: In the Setup hosts networks dialog the behavior is ok - 
improvements should be done when creating new logical networks.
I think neutron integration will improve this...

Ad 3:
When changing (or adding) an ip address I first have to verify what's the
current ip configuration of this host.
If I don't use dns/static hosts entry I can see the current ip address
of ovirtmgmt host in hosts tab, but for all other networks or when
having hostnames configured I have to go to the "Network Interfaces"
subtab of each host. In this tab I can already see the address I (properly)
want to change or the interface where I want to add a new ip address.

So why not allowing to edit ip addresses here?
I don't mean going back to oVirt 3.0 style but just make existing ip
addresses changeable here already by making the existing ip address 
clickable and open the edit network window.

Bondings/logical networks should stay in setup host networks and there
should also be a gear icon to edit/remove logical networks like in the 
DropDownMenu.png screenshot which reveals when clicking on it. Then you
have the possibility to change the ip config wherever it's easier for you.

I also vote for removing the tooltip on logical networks and instead display
the ip address (and maybe MTU) below the logical network name.
e.g.
ovirtmgmt (VLAN 1)
IP: 192.168.0.1
-
logical network 1
-
logical network 2

As ip addresses will most likely be configured only for ovirtmgmt, display
network and storage network this dialog wouldn't get floated with too many
information...

Ad 4: Add a gear icon in the same way as for 3, but keep the ability to
change the configuration only in "Setup hosts networks" dialog, no need imho 
in "Network Interfaces" subtab...

I mainly use ipmilan in oVirt/RHEV/clusters as this works fine on newer
generations where fence_ilo sometimes doesn't.

Hi,

Thanks for starting this thread again.

Great!


> V Integrate Nagios/Zabbix monitoring - via a ui plugin


Zabbix isn't working yet with my ui plugin (is there maybe another one
which integrates Zabbix?) - but it will be available in a future
release.
Btw, there will be a new version of the monitoring ui plugin with new
features available out at the end of this week...

This is definitely one feature I would like to see.

The next feature I would like to request.

Cool. Can this be done on oVirt-node as well or only on
CentOS/RHEL/Fedora hosts?

Vote for this again :)

At the moment spice support is really a pain (especially on Windows as
the SpiceX.cab is missing). Great to hear that spice support has
improved and Chrome can be used as well!

ISO and export domains on FC/iSCSI would be good to have as well.

Additional features I would like to see are:
- oVirt guest agent for Ubuntu/openSUSE/SLES/Debian *

*Ubuntu is already available thanks to Zhou Zheng Sheng

- Resource pools
At the moment only Quotas are available (which is great, btw), but in
some cases it's necessary to implement resource pools. E.g. Limit CPU,
Memory and Network for group of test vms, but give full resources to
production vms. Maybe this could be done with cgroups?
So e.g. I don't want to give a compile machine a full cpu core, but only
1 core with 500MHz or limit the bandwith to e.g. 10Mbit/s.

- Upload ISOs within the GUI to ISO domain

- Use existing share for ISO domain
When creating an ISO domain, oVirt creates it's own directory
structure with IDs. It would be nice if an existing share could be used
(e.g. an ISO share on NFS server which is used by other service, too)
without creating the structure with IDs. I know that the IDs are needed
internally but I think it should be possible to reuse an existing share.


Last but not least I want to thank all contributors of this project for
their great work so far!

René

[Users] oVirt Solaris support

[Koch (ovido)]

Hi,

I want to start the discussion about Solaris support on oVirt again, as
there was no solution for it yet.

On my oVirt 3.2.2 environment I installed Solaris 11 U1 with the
following specs:
* Operating System: Other
* nic1: rtl8139
* Disk1: IDE (Thin Provision)
* Host: CentOS 6.4 with qemu-kvm-0.12.1.2-2.355.0.1.el6.centos.7.x86_64

These are the same settings as on my RHEL 6.4 KVM host (except I can
choose Solaris 10 as OS in virt-manager), which has KVM version:
qemu-kvm-rhev-0.12.1.2-2.295.el6_3.2.x86_64 (I wanted to use this host
as a RHEV host, so the qemu-kvm-rhev package is installed in case you
wounder)...

What's working:
* OS installation on IDE disk
* Bringing up network interface

What's not working on oVirt:
* Network connections  - on RHEL 6.4 with plain libvirt/kvm this is
working...


I can see the mac address on my CentOS host, but can't ping the Solaris
vm:

# brctl showmacs ovirtmgmt | egrep '00:99:4a:00:64:83|port'
port no mac addris local?   ageing timer
  2 00:99:4a:00:64:83   no10.72

# arp -an | grep '00:99:4a:00:64:83'
? (10.0.100.123) at 00:99:4a:00:64:83 [ether] on ovirtmgmt

When using tcpdump on the vnet interface which belongs to the Solaris vm
(ip 10.0.100.123) I can see ARP requests from the vm for ip address of
my CentOS host (10.0.100.42) but no response to it. Same when pinging
other ips in this network:

# tcpdump -n -i vnet2
tcpdump: WARNING: vnet2: no IPv4 address assigned
tcpdump: verbose output suppressed, use -v or -vv for full protocol
decode
listening on vnet2, link-type EN10MB (Ethernet), capture size 65535
bytes
18:15:35.987868 ARP, Request who-has 10.0.100.42 (Broadcast) tell
10.0.100.123, length 46
18:15:36.487399 ARP, Request who-has 10.0.100.42 (Broadcast) tell

18:15:36.987536 ARP, Request who-has 10.0.100.42 (Broadcast) tell
10.0.100.123, length 46

I also compared the qemu-kvm process list on the KVM with the oVirt
machine and can't see much differences except that oVirt has more
information like smbios
oVirt host:
/usr/libexec/qemu-kvm

 -netdev tap,fd=27,id=hostnet0
 -device
rtl8139,netdev=hostnet0,id=net0,mac=00:99:4a:00:64:83,bus=pci.0,addr=0x3

RHEL KVM host:
/usr/libexec/qemu-kvm

 -netdev tap,fd=32,id=hostnet0
 -device
rtl8139,netdev=hostnet0,id=net0,mac=52:54:00:51:c2:97,bus=pci.0,addr=0x3

Any suggestions on how to troubleshoot / get Solaris networking running
is welcome.
Changing the interface to e1000 doesn't work either.


Thanks,
René

Thanks a lot for your answer and sorry for my late response - I was sick
leaving last week.

# brctl show

vnet1 is a Debian 7 vm which has a perfectly working network.
vnet2 is the Solaris 11 vm which can't communicate over the network.

10.0.100.42 is the ip of the oVirt host and it's ip is configured on
this bridge (and reachable from the Debian 7 vm):

# ip a | grep ovirt

Yes, I can see them:

Great work - thanks a lot for the Debian and Ubuntu packages!

Just one little thing:
Can you add python-apt to the dependency list (it's missing in the
Debian Wheezy package - didn't test the Ubuntu packages but maybe it's
missing there, too)?

If python-apt isn't installed it's not possible to fetch installed
packages:

MainThread::INFO::2013-09-16
15:23:22,977::ovirt-guest-agent::37::root::Starting oVirt guest agent
MainThread::INFO::2013-09-16
15:23:23,015::GuestAgentLinux2::101::root::Unknown package management.
Application list report is disable

GuestAgentLinux2.py requires this python module to get the package
information.

All other features like system shutdown, nic information, memory,... are
working fine.

René

You can export them to your export domain on ovirt manager 1, detach the
export domain afterwards, attach it to ovirt manager 2 and import the
vms.

Yes, indeed it does (even I have no clue how this can influence
networking).
When adding cpu model to my plain kvm machines libvirt xml network isn't
working anymore.
I'll test with some hook scripts if removing the cpu model will solve
the network issue for my oVirt Solaris guest.
Thanks for the hint.

Did you try to create a new one or import an existing one?
You have to import it, but make sure that it's not activated in your
other environment.

I managed to get Solaris networking running when removing cpu model and
cpu match attributes, which are added by oVirt but not by virt-manager.

I created a hook script (99_fix_solaris) which removes these
information. Afterwards networking is fine in Solaris guests:
https://github.com/ovido/ovirt-stuff/tree/master/hooks


Just one question renaming:
Is there any downside from oVirt side when removing these cpu
information like e.g. features aren't working as expected?


Thanks all for the hints.

René

No problem.

Btw, are you (or anyone else) working on getting the guest agent into
official Debian/Ubuntu repositories?
Your packages are working really well, so it should be not to hard to
get them into official repos...

That's very interesting as most other projects sometimes react not
really cool if users/companies announce commercial services.

The company I'm working for / I co-founded (company name ovido - located
in Vienna, Austria) is offering professional services for amongst others
Linux, monitoring and virtualization like consulting, trainings but we
also support these installations. Our main virtualization focus is RHEV,
but for some customers oVirt is - for various reasons - the solution
which fits better their need.

As we really like oVirt and RHEV we try to spread out the word with
magazine articles or presentations on open source events (mainly in
Austria and Germany). Besides this I started open sources project like
the check_rhev3 Nagios/Icinga plugin and the ui plugin for
Icinga/Nagios. What we don't do is announce our offering of commercial
services in an obvious way in mailing lists.

Your hypervisor must be CentOS 6 or Fedora 18/19 in order to be able to
manage it with oVirt (other Linux distributions are still a wip).

As oVirt has a totally different concept as virt-manager you have to
import your machines into oVirt. As Markus already wrote this can be
done using virt-v2v.

Does your engine really need access to the storage?
ovirtmgmt network should be sufficient in most cases.

You can configure the network of engine using your favorite editor and
edit/create /etc/sysconfig/network-scripts/ifcfg-* files...

I totally agree that configuring the network directly on the hosts
should be avoided.

I think I misunderstood the issue of Rickard - I thought he has issues
configuring network for the engine itself. 
But (after reading your last email with your suggestions) the question
is how to define logical networks in engine and deploy config on hosts
(if this is the case please don't do any configuration manually with an
editor.)

You can for example use Nagios/Icinga with the event handler
functionality. When your vm is down, Nagios/Icinga can start it again
via an event handler script (which will use Pyhton SDK or REST-API to
start the vm).
