==Installation and upgrade === Is it possible to run x86 container on a x86_64 arch? =====:Sure :) We actually did some work on that to enable migration of x86 container from x86 to x86_64 and back, and to enable using 32-bit iptables in 32bit container on an x86_64 system.
===== What filesystems should I choose for saving my containersHow to install OpenVZ? =====: The safest choice is ext2/3 to save your containers. Remember that ReiserFS is less stable than ext2/3.: If you choose to use XFS, there will be no support for disk quota inside containers.
