Yes, indeed it is. What distro is this ? Do you have SELinux or any other
security feature enabled ? Can you please verify that the file has a
appropriate label if SELinux is enabled ? (ls -lZ /dev/vfio/vfio)

Oh and one more thing! You already answered before but just wanted to confirm
that you don't have apparmor running, right ?

I think this should be enough to spit out the error, there's no need to actually
boot a guest image.

Just, try using a different slot number.

You may need to detach all VFs if they are in the same iommu group.
Also, check if dmesg has any relevant messages when this error
occurs.

What version is the kernel version on the host ? Can you try latest upstream -
4.1 maybe ?

runs L2,
you don’t have to worry about using —enable-kvm. Hyper-V should automatically
detect available
hardware features available to it and attempt to enable hardware virtualization.

p so far.
BTW you are mixing up cases by using/not using "-enable-kvm" in your command
line. What I mentioned is specific to kvm only, qemu probably will always
return a 0 for certain msrs (like this one).

I am assuming you are running a Windows L2. So, what might be happening is
that the L2 guest might be trying to access the enlightenment msrs which

I think this means that KVM gave you a list of msrs but
when you tried to set them, it could not set all of them and hence, the
assert triggers.
Are you using a modified kernel ? There could be something useful in the
host
