Hello, We are in the process migrating vpses from Vituozzo node to OpenVZ node. We tried many methods but none of the worked. If anybody could send a good procedure to do this migration that would be very helpful. Thanks in advance for the help. Regards, BobHi, Please someone help me I am facing below problem Installed OpenVz in one of our server. 1. Downloaded rpm for kernel, vzpkg, vzquota etc all are working fine. But when installing rpm -ivh vztmpl-fedora-core-4-2.0-2.i386.rpm Says it is already installed But when we are giving rpm -ql or rpm -qa it shows it is not installed. 2. Giving vzpkgcache command
What is your kernel version? Any messages in dmesg?
Hi, anything in dmesg? did you try to increase loglevel (LOG_LEVEL variable in /etc/vz/vz.conf file)? Set it to 10, please. You can also use --verbose option with vzctl utility. How much RAM do you have? What kernel are you using now (uname -a)? Thank You!

Try to not load conntrack iptables module(s) on startup and see if it helps (after a clean reboot).
i might be wrong but do i not need conntrack for my APF (advanced policy firewall)? i understand RAB (Reactive Address Blocking) does not work in OpenVZ, does that mean i can also simply drop conntrack?
