Re: [libvirt] qemu driver fails to load on Xen after be0782e1

Problem is the Xen kernel does not provide any huge page info in
/proc/meminfo
xendom0 # cat /proc/meminfo | grep -i huge
xendom0 #
BTW, I think this would be the case for any kernel with
CONFIG_HUGETLB_PAGE turned off.
Michal, short of always building with '--without-qemu' on a
Xen system,
is it possible to make detection of huge pages less fatal wrt loading
the qemu driver?
E.g. assume zero/default for entries not present?
