Hi,

I found a strange thing with vzmigrate.
When I migrated a VE to an other node, the process destroyed the source,
even I specified to keep the original one.

I patched /usr/sbin/vzmigrate to avoid the legendary missing ']'.
I did not download the git version, because as I browsed the changelog,
I did not find this problem in the descriptions.
(Anyway, this commit should win the competition:
http://git.openvz.org/?p=vzctl;a=commitdiff;h=e0961ad15b8a6283f3a6dc1f2ef34ea6ef63905b 
It is really good ;)


Well, let's see the complete process (documentary):

My question, is this a new bug or I missed something?

Ok, now I know, the default behaviour is to destroy the source, if '-r
no' is not specified.
I looked into the vzmigrate script.

So, there is no strange things :)
