Some of my virtual machines (using MS Virtual PC) recently started to show a very annoying behavior: from time to time (at random intervals) the virtual machine pauses/freezes for one minute. During these pauses, I can't do anything in the virtual PC.
- The host system is Windows 7 Enterprise (64 bit). The machine is quite powerful, and the problem ocurrs even when nothing is running on the host.
- The guest system is Windows XP. It has 1500 MB of memory assigned to it.
Any ideas how to diagnose this problem and find the reason for it?
