Greetings:
I run Debian-5 (Lenny) as my OpenVZ host OS with 3 Ubuntu-8.04 LTS VE's
and a Debian-5 VE.
Question: I'd like to upgrade the production 8.04 VE's to 10.04.
Can this be done?
I tried searching but couldn't find a definitive (recommended) procedure
for performing a "distribution upgrade" to production VE's.
Is there such a procedure?
Thanks.
Michael

This stuff may be inconsequential... Did dpkg abort here or was this just
stderr output you noticed?

What does this machine's syslog say about klogd failing?
Read it through /var/lib/vz/root/1041/var/log/syslog or similar.

You removed udev, which controls /dev entries (wrongly in a VE, I guess),
but once you get rid of it, we're still not sure if the static /dev entries
got back in place, esp. if it's not working.
The linked bug report indicates that vzctl enter needs /dev/ptyp0. Can you
list the contents of the /var/lib/vz/root/1041/dev directory and see if it's
there now? If not, run "vzctl exec 1041 /sbin/MAKEDEV ptyp" and see if that
creates it?

2. That which causes joy or happiness.

No, this was stderr I noticed

Josip,
Thank you very much for your suggestions. I think the amount of
thrashing (detective work) done so far to problem-solve this seems to
indicate that there is no clean LTS distribution upgrade for this VE.
I think I'll spare my cycles and instead migrate the data on the 8.04
VE's to 10.04 VE's. Thank you.
