running with a much smaller disk which during a "df"
presents a problem, it shows the smaller disksize. If I
understand the arbiter correctly, then there is no need to
match the size of the "real" bricks, so is this by design?<br

Good point, I think for statfs i.e. syscall used by 'df' we need
to ignore the output from arbiter brick. Thanks for this input. We
will raise a bug and work on it. You shouldn't see any problems
because of this issue though.<br>

statfs in AFR picks the brick with the least available free space
for displaying the output. Assuming all 3 bricks are up, the statfs
never picks the arbiter brick, so this problem won't be hit?<br>

qemu libvirt did not work for me, it just hangs with high
cpuload on libvirtd. Should this work?<br data-mce-bogus="1">

Just to isolate the problem does it work if you try to use the VMs
through fuse mount?<br>

Could you give all the logs in /var/log/glusterfs and also the
libvirtd logs.<br>
