We plan to improve and release our template building system soon. Then
is to have (apt like) appliance repositories (and debian like control
So you will be able to build your own appliance repository soon.

But I will discuss that on the openvz list as soon as I have time to do

Yes, it is still unreliable. Unfortunately the openvz team does not fix
those bugs in kernel 2.6.24. I guess if more people report errors they
increase priority on that (hint).

No, backups should be fully functional. When you create a new job you
select the Node - please can you test that again.

We use the stock VNC client, only some minor fixes (signed applet to
cut and paste)

many thanks for this report.
