Package: qemu-system-x86 Version: 1:2.1+dfsg-12+deb8u6 Severity: important Research indicates this has already been found by others, but there is no mention in Debian's bug DB. QEMU generates simulated USB hubs if one attempts to simulate plugging in enough devices, but apparently fails to remove the simulated hubs if the simulated devices are removed.
This makes it impossible to load VM snapshots which were saved with a simulated hub being present. I found two bugs on the QEMU bug DB (hosted by Launchpad/Ubuntu): https://bugs.launchpad.net/qemu/+bug/1586611 https://bugs.launchpad.net/qemu/+bug/1586613 Run `loadvm snapshot` in the monitor and get: Unknown savevm section or instance '0000:00:01.2/2/usb-ptr' 0 I'd rate these as pretty important since being unable to reload snapshots saved at crucial times is a pretty major problem. Ideally `qemu-img check` would be able to detect the presence of the unneeded emulated hubs and be able to remove them. I'm in rather urgent need of a tool to strip out the phantom USB hubs as that is likely the quickest way to resurrect these valuable snapshots. -- (\___(\___(\______ --=> 8-) EHM <=-- ______/)___/)___/) \BS ( | ehem+sig...@m5p.com PGP 87145445 | ) / \_CS\ | _____ -O #include <stddisclaimer.h> O- _____ | / _/ 8A19\___\_|_/58D2 7E3D DDF4 7BA6 <-PGP-> 41D1 B375 37D0 8714\_|_/___/5445
