Re: [ovirt-users] Failed to open grubx64.efi

[Yuval Turgeman]

Boot partition reqs should be handled the same on both ovirt node and
centos (or rhel) and you having to add this manually on rhel can give us a
hint that this is a bug in anaconda (doesnt detect efi?).

In other words, if you need to add this to rhel you'd need to add it to
ovirt node and autopart shouldnt scare you off, just follow the
partitioning guidelines, add your changes and you are all set.  You can
grab some ks examples here:

git clone https://gerrit.ovirt.org/ovirt-node-ng

Hello,

what you're saying is exactly what we designed and implemented in a
test env, in few months we'll move to production.

We have two EMC VNX arrays supporting our storage, one in our main
site, one in our DR site. We're using FC, not iSCSI, but the idea
behind is the same.

We have this setup in the main site:

- hosted-engine
- one storage domain not replicated (needed for completing the setup)
- some storage domains replicated via storage replication (EMC
MirrorView). From the ovirt point of view are standard storage
domains.
- some networks, let's call A, B, C.

On DR side:
- hosted-engine
- one storage domain not replicated (needed for completing the setup)
- Exactly the same networks configured with the same name

Data are replicated with a RPO of 1 Hour, so we need that OVFStore on
each storage domain is up to date.
We call the API for updating the ovf_store of each replicated SD (as
Yaniv suggested in
https://www.mail-archive.com/users@ovirt.org/msg43896.html ):

POST api/storagedomains/{sd_id}/updateovfstore

In this way not only the VMS disks are replicated, but also VMS
hardware informations.

In case of disaster what's happening?

On the recovery side we set the disks on VNX Storage as R/W accessible
(Promote to Primary Image). Then disks are made available to the
hosts, that can the use the "Import Storage" to attach them.
You'll be warned that SD are marked as up in another datacenter, but
you can clearly ignore that message because the "other" datacenter is
now offline due to the disaster.
Once attached the SD, you set them as available (SD are imported in
maintenance mode). Once Available, go to each SD, select the tab "VM
Import" and you can so import any VM that are inside them.
If you created all the required networks, with the same name, vms will
be already connected to the network so powering on is the last action
you require.

I did it manually and works. I'm now waiting to have all the necessary
support from my colleagues to start developing a full DR Solution to
replicate this behavior though python.


Let me know if you need any clarification,

Luca

Re: [ovirt-users] Issue with ovirt-ansible-roles

[Luca 'remix_tj' Lorenzetto]

Hello,

a quick resume of my issue. I haven't really solved yet because i'm
hitting a pair of bugs, but Ondra Machaceck helped me troubleshooting
and finding out the bug.

We had a conversation out of the mailinglist, so i've been to send him
uncensored logs.

First thing he suggested me is to introduce a change to:

 /usr/lib64/python2.7/site-packages/ovirtsdk4/__init__.py

and change line 468 to:

 raise Error("Failed to read response: {}".format(err_list))

So i had a more informative error. This is clearly a violation of the
principles of the zen of python, because the error was not explicit
and is somewhat a bit silenced.

Error changed then to:

Error: Failed to read response: [(,
6, 'Could not resolve host: ovirtengine.intranet.**y; Name
or service not known')]


This is an ansible bug: https://github.com/ansible/ansible/issues/19278

Since my password is (not the real one) "compan", ansible hides any
possible entry of "compan" (the password) in all the parameters. So
ansible scrables the params and the module is instructed to connect to
the url ovirtengine.intranet.**y and not to
ovirtengine.intranet.company.

The only workaround available is to have a password that is not used
anywhere else, or ansible will replace pieces of parameters with
sequences of *.

Weird, but that's it.

Thank you Ondra for the RCA.

Luca

Hi,

on the same hardware i can install with success rhel 7.4 using UEFI.
This required to change my default partitioning to another one
containing
/boot/efi/ partition, adding this entry:

part /boot/efi --fstype=efi --size=200 --ondisk=sda

I suppose that autopart doesn't create this partition.

We have setup vlan taging to utilize the 2 internetal network
interfaces (originally enp6s0 and enp7s0) to be configured with
mulitiple networks each.  We eventually added 10Gb nics to all servers
to improve san glusterfs performance which is enp3s0 which replaced
enp6s0 in our setup.
enp3s0.106 = ovirtmgmt network access to private internal networks
onlyenp3s0.206 = private network bridge PRIVATE used for private
internal network access for VMsenp7s0.606 = is used for public access
for both VMs (bridge) and each host/cp/san in our ovirt setup named

Hi,

This is probably an easy thing, but I can't seem to find the solution.

On my oVirt node 4.1 I have some NFS shares that I want other hosts to reach, 
but I noticed that the firewall is not open for that on the host.
So, how to I configure the Nodes firewall?

Re: [ovirt-users] Failed to open grubx64.efi

[Yuval Turgeman]

Hi,

I tried to recreate this without success, i'll try with different hw
tomorrow.
The thing is, autopart with thinp doesn't mean that everything is lvm-thin
- /boot should be a regular (primary) partition (for details you can check
anaconda's ovirt install class)
This could be a bug in anaconda or in the kickstart that deploys the node
(if not installing directly from the iso), can you install CentOS-7.4 with
UEFI enabled on this machine ?  If you have some installation logs, that
would help :)

Thanks,
Yuval.

[ovirt-users] iSCSI multipathing missing tab

[Nicolas Ecarnot]

Hello,

oVirt 4.1.6.2-1.el7.centos

Under the datacenter section, I see no iSCSI multipathing tab.
As I'm building this new DC, could this be because this DC is not yet 
initialized?

[ovirt-users] Need advise/help/ideas to implement a two sites disaster-recovery with ovirt

[wodel youchi]

Hi,

We want to implement two sites with ovirt and have disaster-recovery, if
site one is unreachable, then site two takes-over.

We will be using iSCSI for Data domains

Our initial idea is :
- install the first site :
   - self-hosted engine
   - iscsi blocks for data domains

- install the second site:
   - self-hosted engine.
   - iscsi blocks for data domain.

Use the snapshot synchronization of the disk-array to sync iscsi
blocks/volumes.

The two self-hosted engine will be independent.
In case of a failure :
 - break the synchronization
 - Access the data domain in site two
 - start the VMs.


oVirt does not manage replication of VMs itself, someone may argue that
it's not it's purpose, but what about selecting the VMs to replicate?? in
case of NFS we may (I don't know really if it's possible) have some access
to the VMs disk files, but in block mode with LVM in it, things become
complicated.

So if someone has implemented such architecture, could you please share the
experience, give advice and ideas on how to best implement this.

Regards.

Please attach the full engine log (at least from the moment you attempted

Do you have access to the host the VM is running on? The vdsm log is

[ovirt-users] After trying to use OVS can't recover a node to use ovirtmgmt

[Juan Manuel Nieto]

Hello,

I've unsucessfully tried in a node to use ovs, now I want to switch back to
use ovirtmgmt but I cant.

for some reason my node is not operational and I have the following on
ovirt-engine.log:

--0--->

<--0---

When I was installing OVS for some reason the ovirtmgmt was removed I
recreated it and its functional.

I'm using Centos 7 and ovirt 4.1.7 the rest of the nodes work properly.
Is there any way to configure this network for this host manually?

Thank you in advance.

The VM interface is virtual. It's not limited or set to 1G. Due to some
ancient Windows certification requirements (that required that an interface
would have a defined speed!), 1G was set for it.

[ovirt-users] ovirt node and logical networks on same physical one

[Gianluca Cecchi]

Hello,
I'm going to setup an environment where unfortunately I will have only a
flat physical class B private network available, for all my scopes.
There are 2 stacked switches where the hypervisors' nics will connect to.
My hypervisors will have 6 network interfaces so that potentially I could
configure 3 bonds: one for mgmt, one for migration, one for VMs.
But this way each hypervisor will have its mgmt ip and its migration ip on
the same lan and also the IP of a VM running inside it will stay in the
same lan.
Is this kind of configuration feasible for a test? Any suggestion based on
these constraints?

If this matter, I'm going to install hypervisors as oVirt nodes

Thanks,
Gianluca

[ovirt-users] Info about xeon mp dunnington support

[Gianluca Cecchi]

Hello,
I should start configuring a lab environment where I should have available
some IBM 3850 M2 servers with E7450 Xeon cpu (also known as Dunnington).
Spec page of processor here:
https://ark.intel.com/it/products/36941/Intel-Xeon-Processor-E7450-12M-Cache-2_40-GHz-1066-MHz-FSB

Can you tell me if they are compatible with oVirt 4.1 for testing; used by
anyone on list?

Base on this following link I presume it should be detected as Penryn from
oVirt, correct?
https://en.wikipedia.org/wiki/List_of_Intel_codenames

I have not them physically accessible right now but I'm just moving to
avoid, if possible, compatibility problems.

Thanks,
Gianluca

Also our default appliance is built from a kickstart file.
You can simply customize it as you need and rebuild your custom appliance
to be used with hosted-engine-setup.

Look here to see how the ovirt engine appliance is built:

The point is that now hosted-engine-setup is strongly using cloud-init to
automatically configure the appliance and execute engine-setup there.
It's simply using the no-cloud datasource which is just a cloud-init
specific iso file attached on the fly as a CDROM; doing it over a pxe boot
will instead require a zero conf network to supply cloud init data and it's
by far more complex.

Re: [ovirt-users] Cannot remove snapshot

[Nicolas Ecarnot]

Le 17/11/2017 à 16:38, Nicolas Ecarnot a écrit :
- export the VM then re-import, if this is related to some LV space 
missing. Then removing the snapshot the usual way.


Self-replying, for the record:

The backing image was seen full of errors by qemu-img check.
I exported the whole backing + img without commiting the snapshot.
I then imported with commiting, and it all went well.

4 hours of doubt.

[ovirt-users] Host Non Operational - Filed to configure management network on host Vollansicht Vollansicht

[jean . hort]

Hey folks,

 

I have an oVirt installation on a dedicated hetzner root server, the server does run the ovirt-engine and it will be used as node.

The installation via ovirt-engine went fine, but after adding a Host to the default cluster hosts (with working ssh connection to localhost!) I get the following errors in the event log after the node went to status Non Operational:

 

"Failed to configure management network on host myhost.net due to setup networks failure."

and

"Host cipherspec.net installation failed. Failed to configure management network on the host.".

 

Under "Networks" I have the ovirtmgmt network with checkbox "VM-Network" and none at "external provider".

 

My hosts publicly available IP Adress is: 46.4.70.9 and the Gateway is: 46.4.70.1 (slightly changed the ip adresses by two digits just for the case).

 

I have the following network-scripts activated:

 

(prior outgoing network interface, now used for the bridge ovirtmgmt):

[root@xxx network-scripts]# cat /etc/sysconfig/network-scripts/ifcfg-enp4s0  
### Hetzner Online GmbH installimage
DEVICE=enp4s0
_ONBOOT_=yes
BRIDGE=ovirtmgmt

 

(the bridge)

[root@xxx network-scripts]# cat /etc/sysconfig/network-scripts/ifcfg-ovirtmgmt  
DEVICE=ovirtmgmt
TYPE="Bridge"
BOOTPROTO=static
IPADDR=46.4.70.9
NETMASK=255.255.255.255
SCOPE="peer 46.4.70.1"
GATEWAY=46.4.70.1
_ONBOOT_=yes
DELAY=no

 

(the (only) route):

[root@xxx network-scripts]# cat route-ovirtmgmt  
### Hetzner Online GmbH installimage

ADDRESS0=0.0.0.0
NETMASK0=0.0.0.0
GATEWAY0=46.4.70.1

 

 

So, long text short: my host has connection to internet, all firewall rules are set correctly (I can access the webinterface, I can ssh to a changed port, I allow root login via key from localhost to localhost).

 

There must be a flaw in my network- or my ovirt-configuration. But yet, I don't know where to check the ovirt-Config so I can't post its config or logs, only my network setup. Hopefully the flaw is in there, elsely, I would be thankful if you can support me to active the (one and only) host as node.

 

Cheers

Re: [ovirt-users] Why was HE Install made OVA only?

[Alan Griffiths]

I was building my own image, using Foreman, Puppet and PXE. There's a
specific partitioning schema I'm required to use in my environment and
building my own image from Kickstart is by far the easiest way to
achieve this.

I can appreciate that in most scenarios the OVA install is the
best/easiest option, but it would have been nice to keep PXE and ISO
options.
