For some reason, the qemu process currently gets trapped by kernel
4.12.5. (qemu-cmd: [1]) Last thing I did was installing the Win7 Realtek
AC97 driver to get guest sound working. I did this with a qxl
configuration, because the passed through USB keyboard was not working
for disabling certified driver enforcement. (qxl xml: [2])
message is:
Sep 7 16:58:52 -host- kernel: traps: qemu-system-x86[4863] trap int3
ip:7f0cbc078024 sp:7f0cab7fd500 \
error:0
Sep 7 16:58:52 -host- kernel: qemu-system-x86 (4857) used greatest stack
depth: 12824 bytes left
I’m also not able to get any Seabios debug output, although the chardev
is present. I tried to specify the Bios. bios-256k gets slightly earlier
output showing the loading files bar, but will result in the colored
stripes, I experienced on the Windows 10 Creator’s Update. bios.bin
seems to be the default and gets further, but will trap before any output is
shown.
Versions:
– Seabios 1.10.2
– qemu 2.9.0-r56
– kernel 4.12.5
Any suggestions?
Thanks,
Manuel
Note: I use the command line here, because libvirt does not allow access
to host alsa devices.
