Hi, Are there any issues running two guest OSs at the same time? I started two Windows XP sessions yesterday, each with about 1.3GB allocated memory, and my Mac Pro halted. A big sign came on I had never seen from the OS telling me I had to restart. Steve Mac Pro OS X 10.4.8 Parallels RC2 Build 1922 6 gB RAM Application and disks on Startup RAID-0 (two 250gb drives) Using "Sleep" method to get VT-x support to work
The "big sign" was probably a kernel crash. I have no problems running 2 (or in one case 3) VM's at the same time on my MacBook. Given I have 2GB of RAM in it, and one of the three VMs was MS-Dos with 32MB of RAM. If my lowly MacBook can handle it then a MacPro shoud be able to do it with no trouble. You probably encountered yet another MacPro bug. See if you can get it to do it again, and then post the logs.
I do run multiple OS's on my Mac Book Pro. I never tried two Windows. Just Linux, Solaris and Windows XP. I have no stability problems. Just so you know. Maybe something specific to Mac Pro?
