[vfio-users] Permissions problem on Fedora 27

[Patrick O'Callaghan]

Since upgrading to F27 yesterday I keep getting a pop-up error on trying to
start my Win10 VM. The message says "unable to map backing store for guest
RAM: Permission denied". I assume this is related to hugepages, which I
use. The journal entry appears to be this:


libvirtd[8610]: 2017-11-17T17:11:41.105867Z qemu-system-x86_64: unable
to map backing store for guest RAM: Permission denied


There doesn't appear to be an AVC denial record, but if I turn off SElinux,
start the VM, then turn SElinux back on, it works.

Any ideas would be appreciated.
