Completely understood, _but_ (see answer below )

Yes, that the problem, my existing server is not 64 bit :(

Ok, i have done all that.

Cool, Ok this is fair enough to me.

Really appreciate it. So we know and could visualise on what happen under the hook :)

Ok, i miss this post, actually I rarely visit zimbra forum, My personal preference is mailling list discussion than the forum ( i do search the forum when i need the answer :)).

> Do you run Zimbra on OpenVZ/Proxmox VE? 

Yes, i do have a couple of Zimbra server running on OpenVZ containner ( Now have been migrate into PVE ). 

I don't know if it was a problem or not, on the containner view under virtualizations menu, i see a 100% CPU usages. When i check the HN CPU by click at Home link on PVE web, it just utilize between 9-20% CPU. So maybe i have miss something here ( The HN is Quad Core 2.66Mhz processor with 8GB RAM). It is a normal behavior that the containner is utilise all the CPU allocate to it all the time?

Don't think, just go for it :) 

Ok, seriuosly, i agree with you. Zimbra is the best and so easy to install Groupware that i have ever tried. If you could create the appliance that run out-of-the-box with PVE, that was fantastic ( I'm sure will give it a try ). From what i have do, it PITA to configure it to run properly with my enviroment on the OpenVZ ( about 1000 user ), need to monitor UBC all the time until it all satisfied the Zimbra need, or you will keep getting the complaint from the user for the slow loading of webmail or unresponsive email systems :(

Look forward for the appliance.

Thanks and Regards,
