[AusNOG] Virtualization Technology

[Sam Wilson]

I'll bite, as the sys admin in the room I am particularly interested in
what the discussion points were. For example I'll be the first to admit KVM
and Xen bridged mode can quickly become painful with LACP, VLAN's and
Bridging all needing their on config. On the other hand the VMWare teaming
has never been a highlight for me (No active-active?).

I wonder if this is more a question of "which vswitch / SDN" versus "which
hypervisor"

Cheers,

Sam
