Cannot automatically restart VM on another host in IBM BladeCenter

Latest response

Hello!

I'm testing RHEV-M 3.1 on IBM BladeCenter-E. There are two HS23 (Type 7875) and one HS22 (Type 7870) blades.

RedHat hypervisor installed on blades, and RHEV-M installed on separate machine running RedHat Enterprise Linux 6.4. Data Center is  configured to use external  iSCSI storage.

Everything works fine - power management tests (bladecenter type fencing) successful for all blades, VM live migration goes with no problem from any blade to any (I use VM running Windows 2008 R2 server).

Now I am trying to test HA by pulling out of chassis blade server with VM running on it, expecting VM will restart automatically on another blade. But it doesn't happen.

VM goes into "status unknown" state, and blade host goes into "non-responsive" state.  Nothing happens next.

VM is made high available with high priority to migrate. Migration allowed for all VM's from any host to any.

What I do wrong?

How to fix this?
