Okay, that works ! I have installed OpenVZ myself and applied the patches
locally. After renaming the readline in the openvz_conf.c to avoid overriding
the system one (and then crashing libvirt), it worked for me on x86_64.
There are slight differences in behaviour, for example shutdown looks
synchronous (but since it's very fast it's not that a big deal).
There is a lot of stuff I would like to change, for example make all
the module functions private, the readline renaming, etc ... What I would
suggest is the following:
- commit the new files to CVS
- apply the patch but make the openvz configure off by default
Then we can work out of CVS, which will make cooperative development easier.
If that's good for you tell me, I will arrange the commits etc,
thanks a lot !
