Xen users - Jun 2010 - XCP 0.5RC2, possible bug, strange error message

I''ve been testing the host-get-vms-which-prevent-evacuation command for
the upcoming 0.3.3 release of XCCS. I created a CentOS VM without the 
guest agent installed, which means that it can''t be live migrated and 
would prevent a host from being evacuated. I did get the correct result 
that the VM wouldn''t allow evacuation (in the right format, thanks 
Dave!) however I got a reason back that doesn''t make any sense to me.

I expected a reason to do with the missing guest agent, what I got was
HOST_NOT_ENOUGH_FREE_MEMORY. I think the error is in error :).

Well... ahem... it''s not ideal but in this context
"HOST_NOT_ENOUGH_FREE_MEMORY" actually means "something is
preventing this VM being migrated. I guess you better shut it down or suspend
it". I agree it''s not really the right error for your situation
:-)

I think we''ll have to fix this up in future.

Cheers,
Dave
