Bug reports, manual pages, etc. I feel like there is a lot of anecdotal evidence, but we shouldn't make our decisions just because somebody says KVM can't do this or Xen can do that. -- ubuntu-server mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam
