Yes, I had an open shell at the time.  Hitting return didn't get me
back to the prompt.  It looks like the VM / qemu is genuinely locked up.

I'm a bit confused about this.  It appears that sending the shutdown
ACPI signal is causing the VM to suspend *AND* resume (is that right?)
But nothing I'm doing should be causing it to resume, since I'm only
clicking on the SPICE console and hitting the keyboard after the
resume has happened.

I verified that the resume happens 'spontaneously' by using
virt-dmesg, which uses a non-invasive kernel memory scan.

Rich.
