Hey All - I am attempting to run a container from a backup...

I am backing up via rsync and trying to run it within a vm. The vm is the
same host, kernel version and just about everything is the same. Whatever I
try, I can't enter the VE; Unable to open pty: No such file or directory

It is indeed there though, I have tried everything I can find. Although
previously I have ran the same VE from a different days backup on this
setup.

All I want to do is be able to take an rsync of a running container and
throw it into the vm for development purposes.

What should I look into first? I have modified the private location but I
have a feeling it is a permissions issue. The host is Debian 5 and the
guest is Ubuntu 10.

Thanks

Hello,
I think it may have something to do with udev. Device files are created
at boot time (you can see a message "waiting for /dev to be fully
populated" when a phisical computer starts) but this is useless in a VE
context.
Check that udev is not being started at boot (does not hurt, but it's
useless) and add /sbin/MAKEDEV tty
/sbin/MAKEDEV pty

in the rc.sysinit file of the VE.
This was explained here: http://forum.openvz.org/index.php?t=msg&goto=34305

Thanks for the info - I have visited that thread previously. I do not know
of such a file for ubuntu, so I did add the commands to /etc/rc.local and
waited a few minutes, I also tried etc/init/rc-sysinit.conf

Again I get the same error. Could there be something conflicting in the
/var/lib/vz/private/VZID/ folder? I did try many things to populate device
files. Also the previous attempt that worked was using udev, and I only had
to run one command and change some perms to get it going.

Thanks
