No.

[Martin Maurer] 
So just move this 3-5 32-bit container to Proxmox VE, what is the problem here? 
You can run 32-bit containers without problems.

Maybe your existing hardware is not 64 bit capable? Ok, then I see the problem.

[Martin Maurer] 
As you know the resource settings are not so easy to understand, especially for beginners with OpenVZ. Therefore we decided to set most parameters automatically, based on your hardware. Additionally, we solved the issues when you run OpenVZ AND KVM virtual machines together on the same host, so PVE management also brings OpenVZ resource Management to KVM, i.e. you can limit CPU resources for KVM in an OpenVZ compatible way. So both systems can run parallel. (On all existing systems I know KVM can eat up all resources, which in effect disable reasonable resource control).

This is possible when you set ORIGIN_SAMPLE="pve.auto" to your existing config after you moved your container to Proxmox VE. you can test this, just add this and then change memory or disk space on the web interface - after you clicked save, the config file is updated. Now compare the new one with the old one and you will see what we did.

All these settings are set automatically in order do not conflict with other virtual machines on Proxmox VE, see above - but you can overwrite them if needed but not recommended.

[Martin Maurer] 
We try to bring a UBC monitoring to the web interface to see what´s going on.

Did you see my posting here about installing Zimbra?
http://www.zimbra.com/forums/installation/17683-running-zimbra-proxmox-virtualization-environment-based-openvz.html
see attached a screenshot of my Zimbra installation (on Debian etch 32).

Do you run Zimbra on OpenVZ/Proxmox VE? I am thinking of building a virtual appliance with Zimbra, personally I think Zimbra is one of the best Linux based Groupware systems.
