zimbra as VM-guest : vbox vs. vmware

[gruad23]

I just want to share my experience. I have zimbra run as VM on a potent host with loads of RAM and unfortunately rather weak I/O-performance (driver-issues with my sas)

The first year I had it run as vmware-server-machine and it was a mess. Especially after upgrading from zimbra5 to zimbra6 system-load on the host went up to dangerous levels. Since then zimbra was getting slower and slower and the hostload bigger and bigger.

A week ago I moved the whole system from vmware-server to vbox and ... voila ... sysload down and zimbra responsive again.

Not sure if its a zimbra-issue with vmware (like some people suspected after 6.x was released) or if its just something on my machine.

Host ist Ubuntu 8.04-64 on a dell R300
Guest ist Ubuntu 8.04-64 as well.

I don't think vbox (virtualbox) is a server virtualization solution.
However, if you're getting good results with it, it's nice for you 8)

About VMWare-Server, it mainly depends on the version.
1.0 works quite nicely while 2.0 is a pain to manage (search this forum).
However, in both cases, "good" performances can only be achieved with vwmare-tools installed (and the VMI kernel is a plus).
