I just set up a new Dell PowerEdge 2900 (dual Xeon 1.6GHz 5110, 2Gb RAM, PERC5 RAID array etc). Very nice server with plenty of spare capacity so I stuck Virtual Server 2005 R2 on it and imported an XP SP2 virtual machine. For a while the XP VM worked fine (faster than some PCs in the school), but then for no apparent reason, every time I started it, the server lost network connectivity. Only symptons (appart from loss of connectivity) where some Info messages from Virtual Server with could not be displayed properly (missing DLL type message). Has anyone had this?
