[vbox-dev] NMI watchdog on Linux guest

[Ricardo M. Correia]

Hi,

I'm trying to set up a virtual machine for Linux kernel development.

One thing that I'd like to do is to use something equivalent to the NMI
watchdog feature to trigger a crash dump when the (guest) kernel suffers
a hard lockup.

However, the NMI watchdog seems to be non-functional on a Linux guest.

Is there a way to enable them?

Alternatively, is there another way I can trigger a panic or crash dump
on a Linux guest when it has disabled interrupts?

Thanks in advance,
Ricardo
