We have intermittent issues which seem to only effect our VM's running SAP / Oracle.
If I VMotion one of these VM's, sometimes, it freezes after VMotion completes and upon opening the console, CTRL + ALT + DEL doesn't work and the mouse won't work either. The machine is also not pingable. The only way to fix this is to hard reset the VM.
I've noticed that this appears to happen only on VM's that are IO intensive. All other VM's are fine. VM's running Windows 2008 R2 with latest VMWare tools. ESX hosts are running 5.5.0,2068190. I'm currently patching to latest 5.5.0.
Has anybody experienced this before?
See the ESXi host resource like memory and CPU, might be HA admission control is not enabled.
