Public bug reported:
Enabling the USB 3.0 controller apparently breaks "live" snapshotting.
To reproduce:
$ qemu-system-x86_64 -device nec-usb-xhci vm.qcow2
then, at the Monitor:
(qemu) savevm
Error -22 while writing VM
(qemu)
Instead, if I remove -device nec-usb-xhci from the cmdline, everything
works fine.
Some QEMU and OS info:
$ qemu-system-x86_64 -version
QEMU emulator version 1.5.0, Copyright (c) 2003-2008 Fabrice Bellard
$ uname -a
Linux localhost 3.2.0-4-amd64 #1 SMP Debian 3.2.41-2 x86_64 GNU/Linux
The same also happens with 1.4.2. All compiled from source, not Debiabn
package (btw, this *also* happens with distro packages/older versions).
