Cannot automatically restart VM on another host in IBM BladeCenter
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?

This one seems like you may need to open a ticket. When you add the new blade, you entered the fencing information (my shop uses Dell (iDRAC)). Did you test an ssh connection from your RHEV-Virt Manager host out to the BLADE CMM? (or did you test from hypervisor itself)? Actually a simple PING from the Virt Manager host to the Blade CMM might indicate what is going on. Also - did you validate the Blade CMM has the correct network information?
I assume your Blade infrastructure has a separate management subnet. Perhaps the subnetting on the CMM itself is not correct? We use DHCP for ours (with DNS updates) to mitigate these types of issues.
