Please feel freel to re-assign as appropriate.

Comment 3 Alon Levy 2013-08-08 13:49:24 UTC

The command line contains both vnc and spice, and uses cirrus. I would like to know:
1. does this happen when using only vnc, without spice?
2. is there any difference when using qxl or cirrus?

There is no qxl driver for win8, and I suspect it has nothing to do with spice either.

hi Alon Levy

Now can not reproduce this bug:
kernel: 3.9.0-0.55.el7.x86_64
qemu-kvm: qemu-img-1.5.1-2.el7.x86_64

Comment 5 Alon Levy 2013-08-12 08:02:33 UTC

Thanks Yun Ping Zheng.

Based on your comment (comment 4) I'm closing as CURRENT_RELEASE (it was either that or INSUFFICIENT_DATA) with 'fixed in' of 1.5.1-2.el7 (btw you said qemu-kvm but copy pasted a qemu-img version string - but since they have the same version and release, it's good enough).
