Use local ansible to talk to engineVM and other vm
by 03ce007＠gmail.com 22 May '18

22 May '18

I have a self-hosted-engine (4.2) running on a centos 7.4 server. I have downloaded ovirt ansible roles from ansible-galaxy and can run them from the server where the engineVM is running and able to deploy new vms, clusters, dc, etc. I have seen the use of ovirt4.py file to target and group hosts which you can target for specific plays. However, the box where self-hosted-engine is running is a physical server but I am looking to run ansible from my local machine instead to manage vms running on engineVM. Is there a way to achieve this? Thank you in advance.

While checking for some patches on one of my ovirt systems I found that the ovirt-4.1-dependencies.repo no longer has a 3.8 version available. I see newer versions but not sure if I just need to change the following to point to it or upgrade to 4.2. baseurl=http://mirror.centos.org/centos/7/storage/$basearch/gluster-3.8/ to baseurl=http://mirror.centos.org/centos/7/storage/$basearch/gluster-3.10/ or baseurl=http://mirror.centos.org/centos/7/storage/$basearch/gluster-3.12/ Does anyone have the correct procedure I should follow?

ovirt with multiple engines
by Michael Watters 21 May '18

21 May '18

Is it possible to have multiple engines with different versions of ovirt running in the same cluster? I am working on a plan to upgrade our ovirt cluster to the 4.2 release however we would like to have a rollback plan in case there are issues with the new engine.

gnome keyring and ssh passphrase?
by Gianluca Cecchi 21 May '18

21 May '18

Hello, I'm starting here in F28 to use gnome session again, after some Fedora versions... I was in Mate up to some days ago and the ssh passphrase was in need to be inserted only once in mater-terminal, because I had this in my .bashrc (I think) export SSH_ASKPASS="/usr/bin/ksshaskpass" Now I see that my gnome-terminal continues to ask my passhprase without giving chance to save it into its keyring. I read this https://wiki.gnome.org/Projects/GnomeKeyring/Ssh but I haven't completely understood it (if it is current) It seems gnome-keyring-daemon is running [g.cecchi@ope46 ~]$ ps -ef|grep keyr g.cecchi 1972 1 0 08:44 ? 00:00:13 /usr/bin/gnome-keyring-daemon --daemonize --login g.cecchi 16480 14954 0 15:11 pts/8 00:00:00 grep --color=auto keyr [g.cecchi@ope46 ~]$ but is there any other setting to do not to insert every time my passhrase? Thanks, Gianluca

vGPU VM not starting
by Callum Smith 21 May '18

21 May '18

Dear All, Our vGPU installation is progressing, though the VM is failing to start. 2018-05-16 22:57:34,328+0100 ERROR (vm/1bc9dae8) [virt.vm] (vmId='1bc9dae8-a0ea-44b3-9103-5805100648d0') The vm start process failed (vm:943) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/virt/vm.py", line 872, in _startUnderlyingVm self._run() File "/usr/lib/python2.7/site-packages/vdsm/virt/vm.py", line 2872, in _run dom.createWithFlags(flags) File "/usr/lib/python2.7/site-packages/vdsm/common/libvirtconnection.py", line 130, in wrapper ret = f(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/common/function.py", line 92, in wrapper return func(inst, *args, **kwargs) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 1099, in createWithFlags if ret == -1: raise libvirtError ('virDomainCreateWithFlags() failed', dom=self) libvirtError: Cannot get interface MTU on '': No such device That's the specific error, some other information. It seems the GPU 'allocation' of uuid against the nvidia-xx mdev type is proceeding correctly, and the device is being created by the VM instantiation but the VM does not succeed in going up with this error. Any other logs or information relevant to help diagnose?
