[opensuse] (OT) which virtual machine that better.

Hi all, Maybe its slightly ot, what virtual machine that better, I'm trying to build entry level vm, only with dual core with 2GB memory, no SAN, only have 2-3 virtual servers. I thought Xen that comes with opensuse or SLES is good enough, but then I see vmware esx-i come with free and well known vendor, also with very small requirement (cmiiw). Have anyone of this list members have run vm (anykind) for real live servers? Would you share about performance, managebility, etc ? Regards, -ARZ™- Sent from my BlackBerry®
