Re: [libvirt] [PATCH] qemu: Allow system pages to <memoryBacking/>

It occurred to me that OpenStack uses the following XML when not
using
regular huge pages:
<memoryBacking>
<hugepages>
<page size='4' unit='KiB'/>
</hugepages>
</memoryBacking>
However, since we are expecting to see huge pages only, we fail to
startup the domain with following error:
libvirtError: internal error: Unable to find any usable hugetlbfs
mount for 4 KiB
NB, if openstack is doing that, it is a bug - in the 4kb case we
shouldn't be using any of this new XML, because we want to be
targetting older libvirt.
ACK

Daniel
