XenServer 5.6 - anyone upgraded from 5.5 yet?
I'm tempted by the dynamic memory allocation and better snapshot functionality. Time to spin up a test host.
Release notes are here: CTX124972 - XenServer 5.6 Release Notes - Citrix Knowledge Center the only note in there that'll affect me is:
"When installing an update to a host through XenCenter, the update may fail if any VMs are set to auto-start on server boot. The workaround is to turn off auto-start in the VMs' properties before applying the update. [CA-41304]"
which is easy to workaround.
