unable to start Windows 2000 installation with IO-APIC enabled -> fixed in SVN/3.0.2

[fuUser]

I tried to install Windows 2k and it fails after loading all drivers and before you can select the drive/partition. It shows something like "starting Windows 2000" and dies with 100% CPU-load on one emulated core. The problem can be tracked back to IO-APIC support, which is needed for SMP support. Setting it to 1 CPU and deactivating V-tx but leaving IO-APIC on doesn't solve the problem.

Host: Windows Vista x64 SP2, Intel Xeon X3220 (Quad-Core), 8GB RAM Guest: Windows 2k (Installer) with integrated SP4

Same problem on Linux x86_64 host.

If you open IO APIC function in installed Windows system, you start a network transmitted, and the system will hung. When I change computer type from ACPI MultiProcessor PC to ACPI Uniprocessor PC, the system will run stable. BTW, if you used multi CPUs in installed Windows system, you cannot change it to one core beacuse it will hung on booting system.

Replying to Nephom:

We're talking about the Win2k installation CD. It should always detect the right HAL and boot, but instead it hangs, no matter whether 1 CPU or 2. No matter with VT-x or without. Only disabling IO-APIC helps which also disables SMP support.

Confirmed. Looks like an old problem, which is now relevant because of SMP. I'll look into it.
