[Qemu-devel] [Bug 723871] Re: qemu-kvm-0.14.0 Aborts with -vga qxl

[Boris Derzhavets <723871@bugs.launchpad.net>]

I commited  build in mentioned  PPA  via

Actually , disabling "-Werror" to build qemu-common_0.14.0+spicev35-0ubuntu1_all.deb.
"qemu-kvm", "qemu" amd64 packages may be built with "-Werror" with no problems.
Please , DON'T install packages from https://launchpad.net/~bderzhavets/+archive/git-spice in 32-bit  environment.

Title:
  qemu-kvm-0.14.0 Aborts with -vga qxl

Status in QEMU:
  Confirmed
Status in “libvirt” package in Ubuntu:
  Triaged
Status in “qemu-kvm” package in Ubuntu:
  Fix Released

Bug description:
  Host CPU is Core i7 Q820.  KVM is from 2.6.35-gentoo-r5 kernel (x86_64).
  Host has spice-0.7.2 and spice-protocol-0.7.0.
  Guest is Windows XP SP3 with qxl driver 0.6.1, virtio-serial 1.1.6 and vdagent 0.6.3.

  qemu-kvm is started like so:
  qemu-system-x86_64 -cpu host -enable-kvm -pidfile /home/rick/qemu/hds/wxp.pid -drive file=/home/rick/qemu/hds/wxp.raw,if=virtio,media=disk,aio=native,snapshot=on -m 768 -name WinXP -net nic,model=virtio -net user -localtime -usb -vga qxl -device virtio-serial -chardev spicevmc,name=vdagent,id=vdagent -device virtserialport,chardev=vdagent,name=com.redhat.spice.0 -spice port=1234,disable-ticketing -monitor stdio
  and crashes with:
  qemu-system-x86_64: /home/rick/qemu/src/qemu-kvm-0.14.0/qemu-kvm.c:1724: kvm_mutex_unlock: Assertion `!cpu_single_env' failed.
  Aborted

  If I use -no-kvm, it works fine.  If I use -vga std, it works fine.
  -enable-kvm and -vga qxl crashes.
