pixel garbage when using qxl
Reproduce this bug using the following version: host kernel: kernel-3.10.0-63.el7.x86_64 qemu-kvm-1.5.3-24.el7.x86_64 1. Boot a guest with "-vga qxl -vnc :1" # ionice -c 3 /usr/libexec/qemu-kvm -M q35 -nodefaults -cpu SandyBridge -enable-kvm -m 2048 -smp 8,sockets=2,cores=2,threads=2 -name rhel7 -uuid 6afa5f93-2d4f-420f-81c6-e5fdddbd1c83 -drive file=/home/RHEL-7.0-20131127.1.qcow2_v3-bak,if=none,id=drive-virtio-disk0,format=qcow2,serial=40c061dd-5d60-4fc5-865f-55db700407f0,werror=stop,rerror=stop,aio=threads -device virtio-blk-pci,scsi=off,drive=drive-virtio-disk0,id=virtio-disk0 -vga qxl -vnc :1 -monitor stdio -spice port=5900,disable-ticketing -qmp tcp:0:4445,server,nowait -netdev tap,id=hostnet0,ifname=guest14,script=/etc/ovs-ifup,downscript=/etc/ovs-ifdown,vhost=on -device virtio-net,netdev=hostnet0,mac=54:52:1b:35:3c:16,id=test Actual results: The screen has no pixel garbage. Additional info: Start guest with "-vga std -vnc :1" and "-vga cirrus -vnc: 1" and the screen has no pixel garbage. Based on the above result, I think this bug is fixed.
