Try to reproduce this bug by qemu-kvm&&spice-server&&kernel:
qemu-kvm-0.12.1.2-2.312.el6.x86_64
spice-server-0.10.1-2.el6.x86_64
2.6.32-303.el6.x86_64

qemu-kvm runs well, can't got the error.
Could please tell me your spice-sever version or detail record of this issue.

I meant it the other way around, exactly as Gerd understood. The problem is that seamless-migration=on requires newer spice-server so if older spice-server is used, qemu _should_ exit with error instead of quiet proceeding.

I can not reproduce as well but checked the build log of qemu-kvm-0.12.1.2-2.320.el6 in brewweb, it does require spice-server 0.12+ to build qemu-kvm for 6.4.

In unfixed qemu-kvm-0.12.1.2-2.318.el6:
In the build log:
'spice-server-devel >= 0.10.1-2.el6' 
DEBUG util.py:256:  0:spice-server-devel-0.10.1-10.el6.x86_64

In qemu-kvm-0.12.1.2-2.320.el6:
'spice-server-devel >= 0.12.0'
DEBUG util.py:256:    spice-server-devel.x86_64 0:0.12.0-1.el6          

So, I will set this bug to verified. Please correct me if I am wrong.
