qemu-kvm 0.15 usb problem

qemu-kvm 0.15 usb problem

[Michael]

Hi All,
After installed 0.15 ( and 0.15rc1) guest VM failed at some point with
USB attached with error:
qemu-system-x86_64: /tmp/qemu-kvm-0.15.0/hw/usb.c:336:
usb_packet_complete: Assertion `p->owner != ((void *)0)' failed.


host intel,linux-3.0 ( debian squeeze x64 )
start with "qemu-system-x86_64 -m 512 -smp 2 /BIG/Virtual/debian6.base
-usb -usbdevice host:067b:2303"

kvm 0.12.5 works without problem.
Do I missing something?

Looks like a bug.

What kind of device is this?

cheers,

I experienced the exact same problem, a formerly working USB usage
by the virtual machine suddenly caused this assertion to abort
qemu-kvm 0.15.

Looking only briefly at this assertion and the surrounding code,
I found that I did not understand what it's good for, so I removed
the assertion, re-compiled, and - voila! - qemu-kvm 0.15 now works
with the USB device as good as before.

I can say that in my case, a dive computer (a primitive serial device,
I think) caused the assertion.

I am experiencing the same problem with version 0.15 while 0.14 works flawless.
We're using it for an USB ISDN card which freezes the windows host with qemu-kvm 0.15 when "plugged in" while the system is already running or it completely prevents the start of the VM.
We experience the same problem with two completely different USB ISDN adapters.

I can further debug this problem if necessary.

Cheers,

Thomas

Try http://www.kraxel.org/cgit/qemu/log/?h=usb.25.stable

Hi Gerd,

I tried with the branch you suggested but it didn't work either.

The whole WinXP VM crashed once I virtually "plugged in" the USB ISDN card.

I also tried the qemu-kvm-15.1 release but that also didn't work.

Do you have any further suggestions? How can I assist in debugging that problem?

Cheers

Thomas
