Thanks in advance

1. I have dual 300GB SCSI disks (no RAID) on the Node. /sdb is being used for Virtuozzo / VPS while /sda has the OS installed.

How would I go about using the /sda with OS installed as a backup drive for each VPS?

2. Is it recommended to install APF on the NODE itself? If so, what are suggested settings (please attach your conf.apf file if possible)

3. What security measures should be taken on the NODE itself? Please provide every possible security measure that should be done by default.

4. Anyone possibly have webmin applicate template for centos / fedora 4 versions?

5. What is the main difference between OpenVZ and Virtuozzo itself other than OVZ being free, VZ being expensive Smile

It is not recommended. APF uses conntracks, which are not recommended to be enabled for node itself - it may lead to significant network performance looses.

Run as less services as possible on the node. Use it only for VEs administration.

Virtuozzo includes support, GUI and Web-based management tools and some advanced features.

Other fairly big differences are the vzfs file system (a very advanced COW type of file system) that conserves a great amount of disk space when it comes to templated OS distributions/applications, and also because of vzfs, file caching is much more efficient with regards to VEs running from the same OS template.

With Virtuozzo, you can get much more VE density from one hardware node. OpenVZ is just the beautiful core technology and tools that make virtualized environments possible in Virtuozzo. At least that is my take on it.
