Citrix Xenserver 4.1 Beta

Duncan Epping · Jan 31, 2008 ·

Thincomputing.net just posted about a new Xenserver Beta. Looking at the new features list it seems things are finally getting up to speed, especially “bonding of NIC’s” is a must have in a enterprise environment. Hope you can also pin the live migration on a specific NIC in this release, but looking at the specs I don’t think it’s possible.
