Running Zimbra on CentOS 4.5 under Xen (Gentoo Host)

[deckard]

I'm getting ready to do a big migration from iPlanet to Zimbra at work in the next few weeks. We're getting the Network Edition. But, here at home I decided to get familiar with Zimbra a bit more. So I set up a CentOS 4.5 virtual machine on my AMD64 system using HVM support in Xen. I then ran the RHEL version of Zimbra. Although it complained that CentOS isn't RHEL, it installed and worked perfectly. I'm now testing migration of mail with imapsync from my current DBMail install here at home to the Zimbra on a VM (2 gigs of RAM allocated to the VM!). Looks very VERY nice. And this is coming from a happy DBMail/Postfix on Gentoo user. As a sidenote, the Xen host is running Gentoo. My only question is... since I only have four users that I host here at home, do I REALLY need to allocate 2 gigs of RAM?

You can probably get away with less RAM than that but I'd suggest 1GB as the minimum.

Yeah 1 Gb could work ... My idle memory use is 1,3 Gb (running zimbra in unbuntu chroot together with some other services (tomcat,apache,postgresql)).
Succes,

I run under VMware Server from a Gentoo Host and a Ubuntu Client. I initially allocated 256 MB, and things ran okay (4 users). I've upped it to 512 MB, and things are better.
