Moving to distribution

Comment 7 Allon Mureinik 2014-09-14 08:00:20 UTC
Note that these are 3.4 hosts (vdsm-4.14.13).
This issue has been resolved in 3.5.0, and should be backported to 3.4.z.

Comment 8 Nikolai Sednev 2014-09-14 14:21:12 UTC
Works for me on these components:
rhevm-3.5.0-0.11.beta.el6ev.noarch
sanlock-3.1.0-2.el7.x86_64
qemu-kvm-rhev-1.5.3-60.el7_0.2.x86_64
vdsm-4.16.4-0.el7.x86_64
libvirt-daemon-1.1.1-29.el7_0.1.x86_64
libvirt-daemon-driver-secret-1.1.1-29.el7_0.1.x86_64

libvirt-daemon-driver-qemu-1.1.1-29.el7_0.1.x86_64
libvirt-python-1.1.1-29.el7_0.1.x86_64
libvirt-lock-sanlock-1.1.1-29.el7_0.1.x86_64
libvirt-daemon-kvm-1.1.1-29.el7_0.1.x86_64
libvirt-client-1.1.1-29.el7_0.1.x86_64
libvirt-daemon-driver-interface-1.1.1-29.el7_0.1.x86_64
libvirt-daemon-driver-nodedev-1.1.1-29.el7_0.1.x86_64

libvirt-daemon-driver-nwfilter-1.1.1-29.el7_0.1.x86_64

I ran RHEL7.0 guest over RHEL7.0 host and performed live snapshot successfully, then powered off guest-VM and initiated snapshot deletion via engine's WEBUI successfully.

Comment 9 Allon Mureinik 2014-09-14 15:25:49 UTC
Workaround for 3.4.z machines until the fix is backported - manually run "yum install qemu-kvm-rhev qemu-img-rhev"

Comment 12 Gil Klein 2014-09-15 12:07:14 UTC
Moving back to ON_QA, please re-verify with a 3.4.3 build
