I received this error while trying to create a vm (see attachment)?

 

vfio: failed to set iommu for container: Operation not permitted

Odds on, you've got another device in the same IOMMU group as the video card you're trying to pass.  Turning on ACS override or trying a different PCIe slot may alleviate the problem

 

Thank you for your quick reply.  I have done a little poking around and hoping you can see something in the attached lspci output.  I did see a bios setting that allows me to change the primary video card slot (the radeon is currently in slot 5 and the primary is slot 2), could a controller be blocking it? Please share any ideas you have.

Have u tried squids suggestion?

yes I tried the ACS override as well as moving to a new slot (attached lspci info)

also tried the nvidia card which is now device 42: same failure

Can you check what command

mount

shows ?

 

One line should looks like this

 

/boot/config/plugins/dynamix.kvm.manager/domain.img on /etc/libvirt type ext4 (rw)

 

I hade a simmular issue, my qemu.conf have been overwritten in domain.img

//Peter

looks like you suggested. am attaching the conf file also.

 

tmpfs on /var/log type tmpfs (rw,size=128m,mode=0755)

proc on /proc type proc (rw)

sysfs on /sys type sysfs (rw)

/dev/sdc1 on /boot type vfat (rw,noatime,nodiratime,umask=0,shortname=mixed)

/dev/md1 on /mnt/disk1 type xfs (rw,noatime,nodiratime)

shfs on /mnt/user type fuse.shfs (rw,nosuid,nodev,noatime,allow_other)

/boot/config/plugins/dynamix.kvm.manager/domain.img on /etc/libvirt type ext4 (rw)

qemu.conf

mount.txt

Thats looks OK, qemu.conf have all vfio enabled.

 

//Peter

If it helps my computer specs are a Z800 with a GT 720 as the main and a Radeon 6670 for the passthrough.

You need to add a new version of the qemu.conf file with all the needed vfio groups added.

Here is the needed info for it:

I would also suggest you pass through the audio device of your graphics card also, as there have been reports lately about instability problems when only passing through the video part.

I tried the new qemu and still got the same error. I have tried passing with and without the audio. Any other ideas? Should I install an older version of unraid?

Edit your syslinux (main > flash > syslinux configuration).  A few lines under the line "menu default" you'll see the word "append".  Add a space after that word and type the following:

 

vfio_iommu_type1.allow_unsafe_interrupts=1

 

Apply the changes and reboot your system.  Report back if that works.

 

I think we are closer, at least it didn't fail on creation... error : qemuAgentSend:898 : Guest agent is not responding: Guest agent not available for now.  I've included the diagnostics (wish I would've seen this option earlier).

rebooted and looks better. we have passthru. thank you for your help.
