qemu: RDMA migration support
This patch adds support for RDMA protocol in migration URIs.
USAGE: $ virsh migrate --live --migrateuri rdma://hostname domain qemu+ssh://hostname/system
Since libvirt runs QEMU in a pretty restricted environment, several
files needs to be added to cgroup_device_acl (in qemu.conf) for QEMU to
be able to access the host's infiniband hardware. Full documenation of
the feature can be found on QEMU wiki:
