oVirt Engine UI error: changing Storage Domain mount options
by Jp 25 Jun '20

25 Jun '20

Hi, I want to change the mount options to a Storage Domain that is already in use, but got an error from the Ovirt Engine's UI, and the mount point option change isn't getting applied. What I tried: 1. Shutdown all VMs using Disks on Volume 2. Stopped storage Volume 3. Put storage Domain into Maintenance (so Storage -> Data Center -> select Domain -> Maintenance button) 4. Entered mount point options via Storage -> Domain -> select Domain -> Managed Domain -> "Mount Options" field 5. A pop-up in UI had same exact error as a Bug that had been fixed (https://bugzilla.redhat.com/show_bug.cgi?id=1273941) 6. Confirmed the "Mount Options" field had _actually_ kept my new mount point option! 6. Took Domain out of Maintenance 7. Started Volume 8. Checked oVirt Nodes mount point on CLI but my new option isn't listed Is there a way I can change the mount point options via CLI? To get around this UI Bug ...

vm_service.stop in python sdk
by Louis Bohm 24 Jun '20

24 Jun '20

One of the example scripts at https://github.com/oVirt/ovirt-engine-sdk/tree/master/sdk/examples is the stop_vm.py. I am trying to use that to stop a vm however, I am finding that what its doing is similar to pulling the power cord rather then running a shutdown -h now on the system. Is that correct? Is there a nicer way to shutdown the VM in the python sdk? Thanks, Louis -<<—->>- Louis Bohm louisbohm(a)gmail.com <https://www.youracclaim.com/badges/f11e0d65-21ad-4458-895b-2c5b5cb11134/pub…> <https://www.youracclaim.com/badges/f11e0d65-21ad-4458-895b-2c5b5cb11134/pub…>

import from qemu+tcp still working ?
by Nardus Geldenhuys 24 Jun '20

24 Jun '20

Hi oVirt Land Hope you are all well and that you can help me. I build a centos 8.2 vm on my local Fedora 32 qemu/kvm laptop. Then I ssh to my ovirt host in the following manner: ssh ovirthost -R 16666:localhost:16509. I can then view the vm's on my local laptop with the following configuration string: qemu+tcp://localhost:16666/system. Eveything goes according to plan until I hit the import button. It fails almost immediately. I even tried it on the command line and this is what I get, it also error immediately: virt-v2v -ic qemu+tcp://localhost:16666/system -o libvirt -os SOME_STORAGE centos8_ovirt virt-v2v: warning: no support for remote libvirt connections to '-ic qemu+tcp://localhost:16666/system'. The conversion may fail when it tries to read the source disks.
