hum ...
I tried the next case; shutdown one HV ..
I shared DS 0 using HA NAS.
I got now:
Wed Aug 14 15:09:12 2013 [TM][D]: Message received: LOG I 77 Command

This is logical, because disk.1.iso was created on hostA, then, retrying
to restart VM 77 to hostB encounters an error, because file already
exists ...
The log was generated because I activated the hook to restart VMs on
other HV ...
Then, my VMs was deleted ...
Best regards,
Nicolas
