How to allow trusted OpenVZ containers to access all resources?
I have a dedicated server with 16GB RAM, 2 x 3TB (RAID 0 - i know the risks). I have installed two OpenVZ containers - each with their own dedicated IP. Since these are used only by me for dev/test/compartmentalization purpose, I dont want to restrict each of them to RAM usage and hard disk usage.
- How do I configure each OpenVZ container to be able to use all CPUs, all available RAM and full disk space of 6 TB? Are there any other restrictions I am missing?
Also, is there a way to run 1 htop like app to monitor simultaneously host + 2 containers performance (like htop?)

Just assign them max vcpu, highest cpu count and io priority and max ram when you are creating them.
What zion said, if your using Proxmox you can also monitor the status of the node easily via the panel.
Have you considered LXC? I believe they can take all resources by not specifying any limits.
hadn't really known much about lxc. thx for pointing it out. I am installing lxc on centos 6.5 following instructions . During installation at the end of step
yum groupinstall core --installroot=/var/lib/libvirt/lxc/centos-6-x86_64/ --nogpgcheck -yI am getting error
