<div>Are you sure that's the right list? I don't see any users
there, it's all hard core dev, posting patches.</div>

Definitely. Unlike with OpenVZ, where we have users@ and devel@,
there's only<br>
one mailing list for CRIU, and among the other things it is also
used to get support.<br>

<div>Before I take the plunge and raise my hand there, I was
curious to know if any OVZ 7 user had actually gotten vzctl
snapshot to work.</div>

<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

<div>The last few lines of the dump log contain
these clues:</div>

<div>There is no pid 8366 in the CT but on the host
that pid corresponds to the mysql instance running

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

You might want to try writing to criu list with this
question, they might have a clue.<br>
