I have a KVM guest running on CentOS 5.5 that is in a bad state. I would like to dump the kernel information using magic-sysrq commands, but I cannot figure out how to send a break on the virtaul serial port provided by "virsh console".

The guest is a standard install that will respond if I can send a break on the virtual serial port.

Is it possible to send a break on the virtual serial port?

Thanks, David
