We using ovirt in production environment with each virtual machine with a vGpu。but
serveral days later, I find several phisical server has been crash and automatic
reboot。And I also found some vGpu exist with no virtual machine using. So it makes virtual
machine start fail because of lacking resource.I must enter the vgpu directory and
using "echo "1" >remove" to free this vGpu。With ceaselessly stop
and start, the probability of its occurrence is approximately 0.1%-1%
