Damian Murdoch over at the Australia and New Zealand's Premier Virtualization Community already reported about some enhancements in Virtual center 2.5 Update 2, but wasn’t sure of the release date.
It appears that the VirtualCentre 2.5 Update 2 release will be happening very soon. The current information suggests a tentative release date of July 10th, but it is only tentative. Detail on feature inclusions are sketchy, but there have been a number of resolutions to unreleased bugs like the DRS algorithm problem in VirtualCenter 2.5 Update 1 with debug logging. This problem causes the vpxd process to sit at 100 Percent CPU usage and dump huge numbers of debug logs to disk. Incidentally this is resolved by adding the DumpSpace = 0 parameter to the DRS settings at cluster level. This disables debug logging which actually has no impact on anything else than debugging information.
Among some other errors like the Vmomi.Fault.NoPermission, this issue is now resolved in Virtual Center 2.5 Update 2 due for GA release at the end of July 2008.
