I am debugging a problem with a libvirt VM starting, and I want to see the exact command line that it is going to use to start qemu. Is this possible using virsh or some other utility?

You can consult the libvirt logs in:

/var/log/libvirt/qemu/$vmname.log

Just saw this question. In the hope it helps others, the easiest way to see the qemu command that was used, while the VM is running, is:

ps -ef | grep qemu-system-x86

  • Thanks but this doesn't help. Like I said in the question, I was trying to debug a VM that wouldn't start. The qemu process exited immediately, so looking at the running process list doesn't show what I was looking for.

It is also possible using virsh with the domxml-to-native subcommand:

virsh domxml-to-native qemu-argv --domain mydomain
