kgdb in crosvm

[Jeff Xu]

Hi, 

Is there a way to enable kgdb in crosvm ? 

For example: with betty image in chromeOS on cloudtop instance. 

Thanks

Jeff

Hi Jeff,

If you're looking for info about cros_vm (aka running ChromeOS in a
VM) rather than crosvm (the VMM that is used to run Crostini, ARCVM,
etc.), you might have better luck on the general chromium-os-dev@
list.

crosvm is not used in running betty aside from running another guest
VM like Crostini inside the ChromiumOS image. We don't currently have
a way to use kgdb to debug those guests as far as I know (CONFIG_KGDB
is not enabled at least in the Crostini kernel config, among other
things).

Thanks,
