Ovirt system crash when starting VM with Quadro GPU
by Wesley Stewart 19 Jul '18

19 Jul '18

I have recently been using an old Radeon R9 270X lying around without issue, until this card seemed to have kicked the bucket. I had an Nvidia Quadro P2000 lying around I thought I would try. After installing it into my system, it showed up in the PCI device as anticipated. I based both devices to my Windows 10 guest. It shows up a a GP106GL and a separate audio component. The same thing that happened with the AMD Radeon Card. The events just shows the VM's being terminated without giving a reason, and I am hoping for some guidance. Currently using a single node setup, running ovirt 4.2.3. Any ideas or places to check would be much appreciated!

Python-SDK4: Check snapshot deletion result?
by nicolas＠devels.es 18 Jul '18

18 Jul '18

Hi, We're using ovirt-engine-sdk-python 4.1.6 on oVirt 4.1.9, currently we're trying to delete some snapshots via a script like this: sys_serv = conn.system_service() vms_service = sys_serv.vms_service() vm_service = vms_service.vm_service(vmid) snaps_service = vm_service.snapshots_service() snaps_service.service('SNAPSHOT-ID').remove() This works, mostly... however, sometimes the deletion fails: Failed to delete snapshot 'snapshot name' for VM 'vm'. Is it currently possible to know via Python-SDK that the deletion actually failed? I know I can check the state of a snapshot, but I'd like to check the result of the task. Is that possible somehow? Thanks.

Disk Statistics API in Ovirt

Hi Team, We are using the following API to collect the disk statistics, https://X.X.X.2/ovirt-engine/api/ *disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda/statistics* <https://X.X.X.2/ovirt-engine/api/disks/2331bad7-71ec-4fad-95bb-2b3449f3dbda…> I found one issue in the disk statistics.

Windows VMs won't boot in debug mode
by Andrew X 17 Jul '18

17 Jul '18

Hi Everyone, I've been having problems getting Windows 10 VMs to boot in debug mode after turning on debugging over network (steps below). Also, device manager in Windows is not showing the processors' node which might be related (same reason why Windows is refusing to boot in debug mode?). I don't have any of these problems when I use generic KVM or Proxmox KVM. To turn on debugging in Windows, I do the follwoing from an admin terminal window: bcdedit /debug on bcdedit /dbgsettings net hostip:a.b.c.d port:p key:1.2.3.4 Any help will be appreciated, Thanks, Andrew
