Hello,
I'm using the current 3.0.0 final realease (PUEL version) on Windows Vista x64 SP2 und tried to install the current Gentoo Linux x86 release and the Windows 7 Ultimate RC x86. But both systems were unstable - on Linux the GCC often crashed with a segmentation fault and Windows had various problems during installtion (crashes, bluescreens) and on both systems i had from time to time the "Guru Meditation"-Crash of the whole VM.
Because of the fact that I could not found any other thread which describes similar problems I post it now here. Can anyone help me?

If you need a Log-File of a crashed VM, tell me please and I will post it.

Here is my system and the VM settings:

Host-System:
Intel Core i7-920 @default clock
6GB DDR3-1066 RAM
MSI EX58-UD4P
GF 8800GT 512MB
Windows Vista x64 SP2 / Arch Linux (I had Guru-Meditation errors on both host systems)
The stabilityon the host system was tested with Intel BurnIn Test software (more agressive test than prime tests)


VM-Settings for Gentoo Linux and Windows 7 Ultimate:
RAM: 3072MB
ACPI on
IO-ACPI on
6 Cores
PAE/NX on
VT-x on
Nested Paging on
16MB Graphics RAM
3D Accel on
IDE-Controller: (Linux guest - ICH6, Windows guest - PIIX4)
Audio and USB on (both system were also unstable with both settings set to off)

First thing that you should look at doing is upgrade to version 3.0.2 and see if this help.
Also never give more than 50% of the available RAM to the guest or you will see the guru mediation error.
Almost every virtual machine I have installed will operate at 1024 Meg or under in a virtual environment. You can tweak this as time goes by but a good place to start.
