This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux major release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Major release. This request is not yet committed for inclusion. Also exist on qemu-kvm-0.12.1.2-2.68.el6.x86_64. Does it work w/o spice (although it looks it is a qxl issue) (In reply to comment #4) > Does it work w/o spice (although it looks it is a qxl issue) Yes, it works well without spice, as described in Comment 0. Does it also happen without '-pcidevice host=02:00.0'? (In reply to comment #6) > Does it also happen without '-pcidevice host=02:00.0'? It also happnens without "-pcidevice host=02:00.0", maybe the bug summary need to be modified. :-) Command line: /usr/libexec/qemu-kvm -no-hpet -usbdevice tablet -rtc-td-hack -no-kvm-pit-reinjection -startdate now -drive file=win2008-32.qcow2,media=disk,if=ide,cache=off,index=0 -net nic,vlan=0,macaddr=10:1a:4a:10:90:8f,model=e1000 -net tap,vlan=0,script=/etc/qemu-ifup -cpu qemu64,+sse2 -balloon none -uuid `uuidgen` -monitor stdio -m 2G -smp 2 -boot c -spice port=5930,disable-ticketing -vga qxl 16bpp vga mode (i.e. without guest drivers) is broken. Can probably be triggered with any windows version by switching to 16 bit color depth. Patches posted for review. Reproduced on qemu-kvm-0.12.1.2-2.82.el6, verified pass on qemu-kvm-0.12.1.2-2.90.el6 Steps: 1. boot a windows guest.(I tried win2k8-32 and win2k8-64) 2. change the display setting to 16 bit color depth by: Right-click mouse on guest's desktop -> Personalize -> Display Settings -> Then change the colour to 16bit -> Click OK. On qemu-kvm-0.12.1.2-2.82.el6, guest aborted. On qemu-kvm-0.12.1.2-2.90.el6, guest works well.

Description of problem: Win2k8-32 guest aborted when boot with physical NIC card assigned and with -spice. Using vnc to view the guest, have no problem. Also tried win7-64/32, win2k8-r2-64,winXP-32, also have no problem.
