I will put it in the distribution. I will call it vserver-copy.
There is one issue. It did not work for me :-(
You are using ssh to check if the target dhost/vserver is running
but you are using rsync over rsh to perform the copy. On most machine
rsh is not enabled/installed. So the copy failed without much explanation.
I suggest it does the copy using ssh by default and have an option
to use rsh.
What do you think ?
Something I would like to see in this script is vfile. Copying a whole
vserver takes some time when in fact, potentially most of it is already
available. Using vfiles, you can get the list of all file different from a reference
vserver (potentially different) and copy just that. Then on the target, you can
The vcp script would accept a -r argument, which is the reference vserver.
The script would check that both the source and the target host have
such a vserver and would use vfile at one end and vunify at the other
Anyway, just give your tought about rsh/ssh issue and I will see if I can

vserver: run general purpose virtual servers on one box, full speed!
