Public bug reported:
CVE-2017-9375 fix cause qemu crash on Ubuntu 17.04 if USB 3 controller
is selected in virtual machine properties.
To reproduce this issue:
1. Install Ubuntu 17.04
2. Install package ubuntu-virt
3. Create virtual machine with USB 3 controller
4. Try to start this virtual machine
Error message from libvirt log:
qemu-system-x86_64: /build/qemu-g5EXBU/qemu-2.8+dfsg/hw/usb/hcd-xhci.c:2169:
xhci_kick_epctx: Assertion `!epctx->kick_active' failed.
Workaround:
Switch controller type to USB 2, but AFAIK this is not applicable if user need
to passthrough many USB devices to guest, or if user actually need USB 3 speed.
