I have just migrated 4 VMs from windows server 2003 R2 to windows server 2008 R3. 3 of the machines are working perfectly, but the fourth is running incredibly slow.
Interactivity is mostly OK, but menu drawing is slow - several seconds to draw, when a program sleeps for about 5 seconds, it actually takes over a minute to wake up, and if I show the task manager performance window, the graph appears to be getting updated about once a minute, rather than every second.
To do the migration, I simply copied the hard drive images, and created new machines with the same configuration as on the source machine. I have checked that they are similar (apart from VB version changes).
Has anyone seen this issue?
I've tried recreating the VM, but there was no change in the behaviour. – Simon Callan – 2010-11-16T10:55:41.170
