After upgrading the host OS to Mac OS X Server to one of pre-release 10.6.5 beta builds (before 10H574) you may experience crashes of your Virtual Machines or the Parallels Server host itself.
Resolution
If you need to work on a pre-release 10.6.5 beta build, you can use the following workaround.
Go to the Virtual Machine menu and select Configuration --> Hardware --> Boot Order --> Boot Flags and set the following line to Zero:
vm.mem_anonymous=0
Save the changes and start the virtual machine.
Important: This workaround should be applied to all VMs running on Mac OS X 10.6.5.
