Hello,
I have a VM that I'm passing a GPU through to. The passthrough itself
works great. The issue is that whenever this VM is powered on, the host
will reboot without any interaction from me. The reboot happens anywhere
from 3 - 15 minutes after the VM has been powered on. I have many other
VMs that don't cause this. The only difference between them and this one
is the passthrough GPU. Attached are some potentially helpful outputs.
The syslogs have been truncated from when the VM had been powered on to
the last entry right before the host rebooted.
Thanks,
Craig
one thing you could do is setup kernel crash logging (kdump) to see
if the kernel crashes and why
aside from that the only thing i see is that your gpu is not
in an isolated iommu group:
----8<----
/sys/kernel/iommu_groups/1/devices/0000:00:01.0
/sys/kernel/iommu_groups/1/devices/0000:00:01.1

/sys/kernel/iommu_groups/1/devices/0000:01:00.1
/sys/kernel/iommu_groups/1/devices/0000:02:00.0

it seems it is together in a group with your nic
this can be the cause for the crashes...
hope this helps
