I'd be reluctant to propose this as a tip as is, because it will almost
certainly break networking for some users.
We specifically set pci_e820 to address user problems. I don't know what
the intersection is between those for whom this is a fix and those for
whom shutdown is slow/doesn't happen.

Have you tried the solution suggested here before of shutting down other
vms first, then sys-usb and sys-net? Andrew, I think, posted a simple
script that he uses. I suspect that that will have more impact with
fewer consequences than this proposal, but user experience will be key
here: comments ?
