Windows 10 VM fails to start after upgrade to 6.2

[elmn8r]

I upgraded my UnRaid from 6.1.9 to 6.2 this morning and my Windows 10 VM won't start.  When I try to start the VM I get an execution error:

 

internal error: process exited while connecting to monitor: 2016-09-17T23:34:31.777743Z qemu-system-x86_64: -device vfio-pci,host=01:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on: vfio: error opening /dev/vfio/10: Operation not permitted

2016-09-17T23:34:31.777770Z qemu-system-x86_64: -device vfio-pci,host=01:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on: Device initialization failed

 

I'm not an expert with these systems.  I did try searching around some but didn't hit on anything that helped.  Anyone got any ideas?  Thx.

Have you tried recreating the VM in 6.2 pointing to your old disk image?

 

also, did you follow this in regards to the vm?:

I am encountering a very similar thing, I think my error is almost identical to yours. Previously I had issues getting VM's to work with the graphics card and had to use  vfio_iommu_type1.allow_unsafe_interrupts=1 in my syslinux.cfg - while that still appears to be present, that fix obviously isn't working now for me. There must be some updates/changes to the way Virtual Machines work which has caused it...? Hope a solution is found !

+1 rebuild the VM template. Just have it point manually to the vdisk you originally assigned. If there is concern just create a new one and use your original settings as a reference.
