I've got openvz setup and operating nicely with three VEs (ubuntu7.10, centos4,
redhat9) - but shell job control does not work in any of them.
^Z should suspend the current command inside the VE when in a shell where you've
ssh'd into the VE - but instead it remains inside the current process. I've
checked stty settings and they appear equivalent in both the VE and host.
Have I missed enabling something which is mentioned in the documentation or is
this a known issue?
I'm using 2.6.20-ovz008-openvz1 (built from source) following instructions for
how to build when using Ubuntu as the host OS.
Any pointers to how to resolve this would be appreciated.
Thanks,
Tim.

I have just checked and it works for me (using kernel 2.6.18-028stab051).
Could you try using 2.6.18 (i.e. stable) kernels, or 2.6.24? Note that
2.6.20 (as well as 2.6.22) is frozen and unsupported.

Can you elaborate here?

It hasn't been tested much yet, and still in very active development. We
have an intention to make it stable though.

I starting from a fresh git checkout of 2.6.18 from the main repository and
rebuilt everything cleanly and didn't hit the problem I did with the pre-canned
setup I grabbed before. I can add in the modules I needed and have a nicely
working setup.
Thanks for the pointers to getting away from the non-supported 2.6.20 release
which resolved the original issue. It would be good to see some Wiki entry or
some note somewhere indicating not to use 2.6.20 (and I assume 2.6.22 from your
email) as "frozen" doesn't communicate do-not-use to me at least.
Tim.
