I am currently running LibVirt with Qemu on Debian Wheezy:

It's all working perfectly, including ACPI: virsh shutdown guest. However
when I issue "halt" from the guest, the guest stops but libvirt thinks it
is still running: (virsh list outputs state: running). virsh dominfo does
the same thing: State: running
This is how "halt" works, the machine is still powered on, but
processing is halted.
I believe this is due to the -no-shutdown flag passed to qemu, making
it
stop the CPUs rather than halt entirely.
AFAIU, this flag comes into play when you do a *shutdown* of the
guest. The guest will be shutdown, the virtual machine stops but Qemu
will not exit.
Is this however a bug that the status is not updated correctly?
I've
taken a glance at the source and it should SIGTERM qemu when it sees
the stop, but evidently it isn't.
I think this is normal behavior. As long as Qemu is emulating some
hardware, it is in the "running" state.
If you do a shutdown inside the guest, the domain should be regarded
as shut down in libvirt too.
