Description Haim 2012-07-19 11:56:41 UTC 
Description of problem:

in several cases where migration fails, engine send destroy command to source host where vm is running and thus kill the vm. 

this looks as follows on the engine log:

repro steps:

- start migration - have it failed on some fatal error.
- wait for vm to change status to up 
- vm is killed
