Hello, are the official CentOS 6 cloud images known to work in oVirt? I tried, but they seem not to work in oVirt [1], but on plain libvirt. Are there any pitfalls known during using them in oVirt? Thanks Dominik [1] https://gerrit.ovirt.org/#/c/101117/

VMs stuck at Migrating status in Dashboard- Trying to cancel migration will yield "cannot cancel migration for non-migrating vm"

by paul.christian.suba＠cevalogistics.com

Saw this problem initially on one host. Host was stuck in entering maintenance mode since it could not migrate a VM from itself. Manually shutdown that VM and also restarted the host. After restart, some VMs are stuck in a migrating status while trying to "migrate" to the rebooted host. oVirt Node 4.3.1

How do I make delta clones ? OVM (aka Xen) vs Ovirt

by Tim Tuck

Hi all, I'm new to Ovirt coming from a OVM ( aka Xen ) environment and I'm trying to work out how to do similar things. In my OVM environment I have VMs that are 100GB in size. These VMs are templates that are used for running customer workshops so we create and destroy them quite often. In OVM I can clone 10 x 100GB VM's in about 1 minute, the cloning process just creates a "delta" VM rather than copying the entire 100GB. Those VM's can then be run and the on-disk size of the delta VM grows as it runs and deviates from the master. The same goes for templates, creating a 100GB VM from a template takes only a few seconds. Creating a template from a VM only takes a few seconds. My problem is that I cant seem to do any of this using Ovirt. it appears that there is no way to tell the cloning process " I want 10" like I can in OVM - am I missing something here? In my tests I find that even if a "snapshot" is made, the entire VM is copied rather than creating a delta. Creating a VM from a template is no different in that it copies the entire VM. So... Is it possible for Ovirt to create multiple clones on request ? Can Ovirt do "delta" copies rather than copy the entire VM ? If Ovirt can do these things, how do I set it up to to do that ? Any help appreciated. thanks Tim --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

Re: VMs stuck at Migrating status in Dashboard- Trying to cancel migration will yield "cannot cancel migration for non-migrating vm"

Have you marked your host as 'recently rebooted' (or whatever was the name in the UI)?

Re: VMs inaccessible from Ubuntu/Debian-based OS

by Strahil

Hi, I have just tested ovirt VNC console (.vv file) with remote-viewer and it works. Ensure that you have acees to hosts' ports 5900-5999 , as this is the VNC port. Otherwise you can configure noVNC, but it requires port 6100 (based on memory).

In my understanding virt-viewer and remote-viewer are somewhat the same? (Remote-viewer usin virt-viewer) Should I access the VM's console from the ternimal? I have tried changing the VM's graphics type from spice to spice+vnc but still nothing. All I get is a blank window and a message stating that it cannot access the graphic server. > > Thanks again for your help. > > Maria Souvalioti > > > Sent from BlueMail > On 30 Aug 2019, at 7:48 pm, Strahil <hunter86_bg(a)yahoo.com> wrote: >> >> You need virt-viewer installed on your ubuntu or change console type to spice. >> >> >> Best Regards, >> Strahil NikolovOn Aug 30, 2019 15:35, souvaliotimaria(a)mail.com wrote: >>> >>> >>> Hello all, >>> >>> I'm having an issue the past couple of days.

Health Warning: Cinnamon toxic when adding EL7 nodes as oVirt hosts

by thomas＠hoberg.net

Of course a desktop on a virtualization host isn't really recommended, but actually, managing highly or even high-available supports services as VMs on a set of fat workstations under the control of oVirt can be rather useful... And I prefer Cinnamon so much over the other desktops, it gets installed almost first after setup... Which turns out to be a mistake with oVirt. Anyhow, to make a long journey of hair-pulling root-cause searching short: Installing Cinnamon from EPEL has Otopi not find rpmUtils for one reason or another, even if I can see it on both sides, the engine and the target host. Remove Cinnamon, it works again and you can re-install Cinnamon after. I didn't test re-deploys, but I'd expect them to fail. Don't know if this should be a bug report, since Cinnamon very unfortunately doesn't seem official just yet. This is what you may expect to see in the engine logs: 2019-08-22 09:49:24,152+0200 DEBUG otopi.context context._executeMethod:145 method exception Traceback (most recent call last): File "/tmp/ovirt-BAJG2FYLMu/pythonlib/otopi/context.py", line 132, in _executeMethod method['method']() File "/tmp/ovirt-BAJG2FYLMu/otopi-plugins/ovirt-host-deploy/kdump/packages.py", line 216, in _customization self._kexec_tools_version_supported() File "/tmp/ovirt-BAJG2FYLMu/otopi-plugins/ovirt-host-deploy/kdump/packages.py", line 143, in _kexec_tools_version_supported from rpmUtils.miscutils import compareEVR ModuleNotFoundError: No module named 'rpmUtils' 2019-08-22 09:49:24,152+0200 ERROR otopi.context context._executeMethod:154 Failed to execute stage 'Environment customization': No module named 'rpmUtils'
