I'm setting up a xen environment for zimbra. I know I should probably go down the path of least resistance and use centos, but I'm way more comfortable in an ubuntu/debian world. Ubuntu isn't supported under Xen, but Debian is.
Should I just give up and use centos 4 or 5? I heard 5.1 has some issues, should I just use 4? I'm not using 64 bit, btw.
