[ovirt-users] Testing openstack inside ovirt environment

[Gianluca Cecchi]

Hello,
Up to now I only tested openstack on physical hw.
I would like to make some tests in a virtual environment.
Not considering at the moment cinder and glance integrations provided by
oVirt but full openstack itself.
Are nestedvt and macspoof vdsm hooks the only requirement I should care
about to be able to go?
Also, supposing I go with a preliminar pre-test of openstack in virtual
environment using plain qemu/kvm with virt-manager, it's clear to me how to
enable the nested kvm for the host, but what should be the commands to give
on host side so that the openstack instances will be able to communicate
with the outside world (the commands that in ovirt I presume are run by
the  macspoof vdsm hook).
Thanks in advance,
Gianluca

Re: [ovirt-users] Promiscuous Mode

[Christopher Young]

That may work for me.  I'll look into it.  This is going to be a
production environment (I had previously been running OVirt for over a
year with success, but my hypervisors were standard EL7 servers vs.
OVirtnode/RHEV-H) so I'm looking for the most "official", clean
solution.

I will open a ticket with RH on that one, but if anyone knows of an
alternative or any reason why I should do something different, please
let me know.

Many thanks,

Chris

 I had a related question on this.

 When it comes to ovirt-node or rhev-h, is there anything required to
 be installed on the hypervisor hosts themselves?

 Thanks,

 Hi Clint, you might want to check the macspoof hook features here:

 https://github.com/oVirt/vdsm/tree/master/vdsm_hooks/macspoof [2]

 This should override arp/spoofing filtering, that might be the
 cause of your issues with OpenVPN setup (first guess).

 I am deploying an OpenVPN server in my OVirt environment and I've
 come to a dead stop with the developer support on a topic related to
 OVirt configuration.

 The developer wants me to put the VM's underlying NIC into
 promiscuous mode.

 I've seen this in a VMware environment and I know what they are
 asking me to do, and I'm wondering if there is a clear way to do
 this in my OVirt environment.

 I found "port mirroring" but no "promiscuous mode"

 Cheers and thank you !

 Ivan, because of YOU, I get me weekend back ! It works and OVPN is up

[ovirt-users] Fresh install failing (Hosted Engine)

[Jonathan Sherman]

I want to extend my lab and am trying an install using the hosted engine,
but the install is failing for me:

References used for install:
https://glennsnead.wordpress.com/2016/02/28/ovirt-3-6-installation/
http://community.redhat.com/blog/2014/10/up-and-running-with-ovirt-3-5/

Setup:
Minimal install of CentOS Linux release 7.2.1511 (Core)
Using DHCP with static address (tried without DHCP with same issue)
yum upgrade

Installed packages:
yum localinstall -y
http://resources.ovirt.org/pub/yum-repo/ovirt-release36.rpm
yum install -y ovirt-hosted-engine-setup screen glusterfs-server nfs-utils
vdsm-gluster system-storage-manager mailx

rebooted

Tried hosted-engine --deploy, but it errors out.  I followed various logs
and I _think_ it's failing related to vdsm-tool restore-nets.  I could use
some guidance on this to help track down what's happening and how to fix.

(Note:  I'd very much prefer using the hosted engine vs. another option for
my lab, so I'm willing to put in the time to figure this out.  Thanks for
any assistance!)

Re: [ovirt-users] set up of fibre channel storage problem

[Campbell McLeay]

Hi Nir,

I'd removed the partitions earlier with parted, but I guess it had
left a signature there, so I did as you suggested and that resolved
the issue.

Many thanks!

This usually means the devices has partitions table, and lvm would not overwrite
the device.

You can check this by inspecting the devices with fdisk.

If you are sure that the devices are not used, you can wipe the start
of the devices
like this:

dd if=/dev/zero of=/dev/mapper/36f01faf000e5fd6407d255820b3d bs=1M count=1

After that, you should be able to select the device for a storage domain.

[ovirt-users] set up of fibre channel storage problem

[Campbell McLeay]

Hi,

I've set up a node in a cluster which I would l like to use the
attached fibre channel disks as storage. The ovirt version is 3.6 and
both hosts (engine and node) are running Scientific 7.2. When I select
the fibre channel option in the ovirt manager GUI from the drop down
menu in the storage section, it shows the target disks on the node
host (actually symlinks named as 34 character IDs which I assume are
created by multipathd, which point to the actual device in /dev such
as /dev/dm-3). 'multipath -ll' shows the devices up and running:

When I select those IDs, it says 'The following LUNs are in use' (does

The storage is not mounted and is not being used by any other host.

The tool in this case is "import-to-ovirt", I guess (since they
already run on KVM it must be)?

import-to-ovirt can handle multiple disk images.  If the disk images
are part of a single guest, then you should specify them all in one
command line run, ie:

  sudo ./import-to-ovirt.pl disk1 disk2 disk3 mountpoint

If the disk images are independent guests then you must run
import-to-ovirt three times.

No, you need to specify it by running import-to-ovirt once per guest.

Re: [ovirt-users] Multi-node cluster with local storage

[Christophe TREFOIS]

Hi Pavel,

We setup an extra NFS on one of the hosts, and setup as hosted-engine.

That way, it works for us.

Using Gluster 3-way with CTDB was our initial plan, but we moved away from it 
as it seems unnecassiry complicated.

Kind reagrds,

Hi,

We have all nodes like you (5 currently), and have them setup as NFS instead of 
local storage.

You have slight overhead because it's NFS, but not so much, and it allows you 
to migrate VMs and disks, even if it's a manual disk, eg no HA will be possible.

So yeah, to me, it's a good option given your setup.

Best,

I haven't tried it, but here is a guide on how to add a hook to ovirt-node:

If you want to remove filtering for a single interface, then replace
steps 2 and 3 as outlined in the README.

Thank you very much. Reading the README it appears that there is a
series of commands to run on the engine to make the options to remove
filtering from the vNIC, or the whole VM available. What purpose is filled
by the two scripts that are included in the git, and where do I put them so
that they will be utilized if that's even necessary ?

Thank you very much. Reading the README it appears that there is a 
series of commands to run on the engine to make the options to remove 
filtering from the vNIC, or the whole VM available. What purpose is 
filled by the two scripts that are included in the git, and where do I 
put them so that they will be utilized if that's even necessary ?

[ovirt-users] Tracking asynchronous tasks results in Python SDK

[James Michels]

Greetings

How can I track asynchronous tasks with python sdk? For instance, I want to
copy a disk so I use:

   dcdisk = api.disks.get(id='...')
   act = params.Action(storage_domain=api.storagedomains.get(name='...'))
   action = dcdisk.copy(act)

I get a params.Action object. Now how can I know which ID has the new
copied disk?

Thank you

James

Right, actually we are already doing this after cold merge,
- 
https://github.com/oVirt/vdsm/blob/d87d031ea52eb76aab29cd0c55d7f3b5f0743ccd/vdsm/storage/blockVolume.py#L581
- 
https://github.com/oVirt/vdsm/blob/d87d031ea52eb76aab29cd0c55d7f3b5f0743ccd/vdsm/storage/image.py#L1262

We should start doing this after moving and copying thin disks, and after
live mege.

With live merge, we make sure that the base volume is large enough to
include all data from the top volume. This does overallocation and having
automatic shrinking after that can be nice.

Good idea, If you file a bug and send a patch it will be available in
the next release.

"qemu-img check" reports image end offset. Also it has --output=json option.

Yes. This is how I've moved my stuff from M$ NFS to iSCSI. Note this works well 
since 3.6.3 only, see https://bugzilla.redhat.com/1304405

Too long to wait :) Currently it's hardcoded. It would be great, if it was 
configurable via /etc/vdsm/vdsm.conf at least. It would allow early adopt 
compat=1.1 in el7 environments.
