Unlike GPU assignment, mdev doesn't need the IOMMU to be enabled within kernel,
since the physical parent device takes care of the isolation, i.e. there's an
IOMMU group entry for each mdev created under sysfs, thus a VM can start
successfully.
Since v1:
- adjusted the error msg in patch 1 according to reviewer
- rephrased the commit message for patch 2 to make it less confusing
Erik Skultety (2):
util: mdev: Improve the error msg on non-existent mdev prior to VM
start
qemu: hostdev: Fix the error on VM start with an mdev when IOMMU is
off
