Same problem I have,
Everything is latest version. No problem with dns settings.
No matter I do result is same.
during vmotion 90% stops then I see the "operation timed out"error in virtual center.
Vmotion result sometimes successfull although gives error.
Sometimes vm becomes orphaned.And powered off.
Sometimes its locks the vm and without killing the process(kill -9 pid no)
no way to release vm and re register it via SAN LUN browsing.
Sometimes I see following error in comatibility window
"Migration from esx.xx: No guest OS heartbeats are being received. Either the guest OS is not respondig or Vwmare tools is not configured properly"[/b]
