[Qemu-devel] qemu-kvm-1.0 regression with usb tablet after live migration

[Peter Lieven]

Hi,

i recently started updating our VMs to qemu-kvm 1.0. Since that I see 
that the usb tablet device (used for as pointer device for accurate
mouse positioning) becomes unavailable after live migrating.
If I migrate a few times a Windows 7 VM reliable stops using
the USB tablet and fails back to PS/2 mouse.
If I do the same with qemu-kvm-0.12.5 with the very same VM its working 
fine.

Can anyone imagine what introduced this flaw?

Thanks,
Peter
