<div>I've been running some test containers on OVZ7 beta, and,
while I realize not all functionality is in place yet, they
have been so dependable that I'm starting to depend on them. </div>
<div><br>
</div>
<div>So, understandably, I was looking at backups, and my first
tries with vzctl snapshot failed. I don't want to spend a lot
of time troubleshooting something that's not yet known to be
working, but in case it is, has anyone else had better luck?</div>

<div>Here is the result of my attempt to make a backup:</div>
<div><br>
</div>
<div>
<div>[root@hachi vz]# vzctl snapshot 1001</div>
<div>Creating snapshot {57c8aa0d-1c04-4469-9d1e-c95fab04bd01}</div>

<div>[root@hachi vz]# </div>
</div>
<div><br>
</div>
<div><br>
</div>
<div>The last few lines of the dump log contain these clues:</div>
<div><br>

<div>
<div>(00.570576) Error (proc_parse.c:404): Can't handle

<div>There is no pid 8366 in the CT but on the host that pid
corresponds to the mysql instance running in the container
that I'm trying to snapshot: </div>

<div>
<div>[root@hachi vz]# ps -ef|grep 8366</div>

<div>So, is this something that ought to work?</div>
