Cc: Guest type: Linux
Host type: Windows

Description

Host: Windows 7, 64-bit, VBox 3.0.10, Core 2 Q6600, VT-x = on.

RHEL 3.9, 64-bit guest fails to load from CD. It has kernel panic right after the bootloader.

For testing you can use CentOS, which is free.

Tried in both UP and SMP variations; same result.

My other host: Intel Core i7 965, Windows XP 32-bit SP2, VBox 3.0.10.

OK, enabling PAE allows RHEL 3.9 64-bit to run. Basically VBox should enable PAE for all 64-bit guests, because all 64-bit hardware has PAE too... (so guest OSes may require it).

To resolve this issue, we need to enable PAE for all 64-bit VMs.

update: guest still fails 50% of the time - with kernel panic. Even with VT-x and PAE enabled.

update2: Moreover, PAE does not help the situation. The VM fails 50% of the time no matter if PAE is on/off or if EPT is on/off.

No, PAE is always on for 64 bits guests.

Are you sure ?!

Look at the attached log file. It clearly shows 64-bit VM without PAE. The VBox GUI shows the same.

415 00:00:02.090 Mnemonic - Description = guest (host)

422 00:00:02.090 PAE - Physical Address Extension = 0 (1)

I'm 100% sure. PAE is enabled dynamically as you can see below that part: CPUMSetGuestCpuIdFeature: Enabled PAE

comment:8 Changed 4 years ago by Technologov

Right.

comment:9 Changed 4 years ago by Technologov

Fixed in v3.1.0.

Host: Windows 7, 64-bit, Core 2 Q6600, VBox 3.1.0, VT-x = on.
