I have an interesting problem. I am runnnig ESXi 4.0 Update 1. Windows 2008 R2 runs fine with VMWare tools (without the SVGA driver). Once I start a second Windows 2008 R2 server, they randomly lockup for 30 seconds or more. Ping becomes unresponsive.
I cannot work out what this is. I've tried different network adapters (2, 3, e1000), all have the same issue. Same with GFX card driver.
I'm really at a loss. I have 2xWindows 2003 R2 servers running on this machine fine. Start up one 2008 R2 box, fine, second one, bam. VMs freezing.
HW is: HP DL360 G5, Xeon, 10GB memory, raid 5.
