This error probably is something in /etc/vz/conf
Normally there is a symlink like: 74eb4c58-1325-484c-950c-a4084d6f51ff.conf ->
/vz/private/74eb4c58-1325-484c-950c-a4084d6f51ff/ve.conf
You might have have 2108.conf as a file in /etc/vz/conf and need to symlink
74eb4c58-1325-484c-950c-a4084d6f51
I know of no one who has done an inplace upgrade. You are better off setting up
a new server and copying the containers from the old system to the new system.
Since there are changes in ploop you can do vzmigrate, or something like
manually create the ploop systems on the new server and manually
I don't see any way to automatically mount with discard. On a test server I can

tried it on a Hardware node or within a VE? Within a VE all I got was a

Same here. I have had no issue with mail servers running under o

the problem is the virtual nic is down before the nfsmount tries to
stop and nfsmount waits forever to close the connection to the
server..

I guess it depends on your usage. I used openvz-2.6.27 on gentoo for

This was true (without modifications to the makefile) before Zaptel
1.2.x, but x86_64 builds are very possible with x86_64 arch on current
versions.
Gary,
Have you modified your container conf file in /etc/vz/conf/ to enable
the device passthrough for the zaptel interface?
John
Hi Gary,
Are your containers 64-bit as well? It sounds like you might be trying
to load a 64 bit kernel module / timing device using a 32bit container.
The same behavior happens with dahdi when mixing 64 and 32 bit software
at the kernel level.
