Hi Daniel,

This is my first appearance in this list, so please excuse me if I'm
messing things.

According to your logs, the problem is related with unmounting.  But why it
cannot unmount?  Is the system a SMTP server or is IO intensive? If not,
check you have not opened sessions (vzctl enter) on the guest neither on
the host that are inside the VPS directory (a su command, i.e), and no
other process is using it as basedir.  Use fuse command to check processes
running on that directory.

Did you check this post in the openvz forum?

Hope it helps
Jorge
