I am observing RHEV environment closely and found out that after several fixes, it runs like a charm. But, There is a certain activity that I have to perform every month to keep it stable. That activity is below command:
MAKE SURE OF NO VM is running on that host before running below command:
service vdsmd restart; sleep 90; service vdsmd restart
This command has some constraints; like:
1) There should be no VMs on this Host. VMs should not be migrating on or from this host
2) VMs should not be in a "?" state (if it's ? state VMs will reboot)
3) Run this command only if host shows inconsistent behavior
Please use this information to make it bug free.
