SolusVM version 1.9.00 has now been released.
http://wiki.solusvm.com/index.php/Versions#1.9.01
This release is primarily a fix for the release of vzctl 3.0.30.1 that requires the UB swappages parameter to be set in the containers config before it will start (only VSwap containers have this setting). Todays release of vzctl 3.0.30.2 is supposed to fix this issue, however reports say otherwise.
Virtual servers created with SolusVM 1.9.01 and above will now have the swappages parameter set automatically on creation.
Virtual servers that already exist will need to have there config files patched via a script supplied on the master server. To run the patch you must do the following in ssh on the master:
/scripts/openvz-swappages
This script only needs to be run once to patch the existing configs.
