[Qemu-devel] [PATCH v2] vl: exit qemu on guest panic if -no-shutdown is not set

[Christian Borntraeger <borntraeger@de.ibm.com>]

For automated testing purposes it can be helpful to exit qemu
(poweroff) when the guest panics. Make this the default unless
-no-shutdown is specified.

For internal-errors like errors from KVM_RUN the behaviour is
not changed, in other words QEMU does not exit to allow debugging
in the QEMU monitor.
