After a lot of hassle moving my 028 kernel to a 042 kernel and the ext3 /vz to ext4 I've hit a brick wall. All the current containers work fine, but when i reinstall or create a new one it gives this error on startup:


2015-12-02T01:05:08+0100 vzctl : CT 214 : Error setting device permissions: Cannot allocate memory
2015-12-02T01:05:08+0100 vzctl : CT 214 : Container start failed (try to check kernel messages, e.g. "dmesg | tail")


When checking dmesg I see this:

Maybe a permissions problem.

Check that /vz/private and /vz/root folders have permission 0700 and are owned by user/group root.

Are you using Vzswap or the old beancounters memory management? Maybe something to do with that. Check what the new container config file looks like in /etc/vz/conf/xxx.conf. Compare it to existing functioning containers. Check whether it's ORIGIN_SAMPLE= is using vswap or the old style templates.

Also check the settings in /etc/vz/vz.conf. I think several of those settings have changed from the older version you were using.

Maybe try turn up the verbose/log level in /etc/vz/vz.conf and see what gets generated in /var/log/vzctl.log

Maybe you need to change the command you are using to create the container?
https://openvz.org/Man/vzctl.8

Maybe try set an existing container to use the new vswap way if you aren't already doing that.
vzctl set 777 --ram 512M --swap 512M --save

A lot of maybes for me.
