Can some one help me with this test situation:
I have 2 hosts for hypervisors with power management via ipmilan in one cluster and I'm using NFS storage. On this cluster I've started 1 virtual machine. For example, now it is running on first hypervisor.
After that in testing purpose I've crushed first hypervisor like this:
cat /dev/zero > /dev/mem
(But his power management module is still working).
After ~3 minutes RHEV Manager sad, that "Invalid status on Data Center Default. Setting Data Center status to Non-Responcive (On host hypervisor1, Error: Network error during communication with the Host.)."
Then after additional ~6 minutes RHEV Manager sad "Host hypervisor1 is non-responcive" and at last started migration of my VM to another hypervisor.
So, it's about 10 minutes before my VM come back online!
My question is: Is there any possibility to change some config-files for faster reaction in this situation? Can I configure my RHEV Manager to migrate VM in 20-30 seconds in this situation?
P.S. Sorry for bad English :(
