[libvirt] [PATCH 0/1] Support huge pages in guests

This patch is an update of John Cooper's original work from last month http://www.redhat.com/archives/libvir-list/2009-July/msg00753.html Changes since that patch - We create a directory $MOUNTPOINT/libvirt/qemu inside the hugetlbfs mount point. This is neccessary because QEMU now runs as 'qemu:qemu' in Fedora and thus cannot create files in the root. libvirtd will automatically chown() this subdir to allow QEMU guests access - Don't automatically probe for hugetlbfs mount if runing as an unprivileged libvirtd, since user won't have access to the mount unless administrator has manually created them a subdir. - Change the XML to look like <memoryBacking> <hugepages/> </memoryBacking> This is because I fear we may have more config options for memory backing store in the future, such as whether KVM can use KSM for sharing on the guest. - Add a test case for it in the XML -> ARGV convetor - Document the new XML options - Add the new XML options to the RNG schema - Fix setup & auto-detection of hugetlbfs mount if no qemu.conf file exists at all - Add config parameter to the augeas schema - Move the code which finds a mount point into util.c since its not specific to QEMU
