So this really should work. The bug indicated by Francesco is specificaly against RHEL 6.6 In Red Hat Enterprise Linux 6.6, support was added for libvirt to report whether QEMU is capable of creating snapshots. However, libvirt did not probe for the snapshot capability properly. As a consequence, the snapshot capability of KVM Guest Image in VDSM was reported as unavailable even when it was available, and creating a disk snapshot in some cases failed. With this update, libvirt no longer reports QEMU snapshot capability, and therefore does not cause the described problem.

Hi, we are running the hyperv flags since months in our Win7 VMs without any issue. As we are still on OVirt 3.4 FC20 infrastructure we set them with hooks (and really depend on them). Maybe RHEL related?
