Linux guest and host, guest can't boot with IO-APIC after update to 3.0.12

Reported by: Brian Prodoehl Owned by:

Guest type: Linux Host type: Linux

Description (last modified by Frank Mehnert)

I've been running a CentOS 5.4 64-bit guest (kernel 2.6.18-164.6.1.el5) under a Fedora 11 64-bit host (kernel, with VirtualBox 3.0.10 and ACPI, IO-APIC and AMD-V enabled. After the update to 3.0.12, the guest would no longer boot (it got a kernel panic immediately). I disabled IO-APIC in the configuration, and the guest boots again.

Sorry, I failed to set the guest and host types, both are Linux.

Please add the kernel parameter nmi_watchdog=0 to the guest kernel command line.

Adding nmi_watchdog=0 to the guest kernel command line lets it boot. So, thank you, but the regression was a surprise and it isn't obvious to me why that's necessary.

We are aware of this problem and there will be an FAQ entry for this. Some more explanations will follow soon.

Very glad to hear it, and keep up the phenomenal work!

Actually adding this parameter isn't necessary anymore as of VBox 3.1.2.
