I'm trying to create a FC6 64 bit VE and not getting it to work. I did an install of FC6 and copied all the files over. Then I copied the /dev directory form a working VE and a few other tricks. But - I'm getting this error when I try to enter the VE.

Unable to open pty: Mo such file or directory

What does this mean?

Have you installed kernel from rpm or built it yourself?
In the second case post .config file please.
Also please post the output of the following comands
on HN after starting VE:

cat /proc/mounts
ls /vz/root/<veid>/dev

Thank you.

You forgot about `cat /proc/mounts` output after VE start, Rolling Eyes

Thanks

Hmmm... seems to be ok.
Then can you post also strace of `vzctl enter`?

I'm not shure but i think it should be this bug that i've already reported and there is also a fix for that:

Seems, that disaster is right! Smile

Do you use kernel older then 2.6.18-028test10?
If "yes", then move to the latest.

Thanks.

In my case the /proc directory is empty. Apparently it's not running something that it should at startup to activate it. What should be in fstab?

How are the scripts in the /etc/vz/dists linking to the VE. I'm a little confused about how those scripts are run?
