Hi Leonelli,
Your error message looks like you've switched to using xapi on XCP - is that
right? (though xend may well raise the same sort of error...)
I'm not sure whether this is correct for xend, but for xapi, the message names
are 'VM.start_on and 'VM.pool_migrate' - with both V and M capitalised.
