qemu-dm dom0 high CPU usage when usbdevice=tablet
Hey guys, It seems like the qemu-dm processes on the dom0 use quite a lot of CPU when usbdevice=tablet is used for a Windows a guest. Setting that to 'none' fixes the problem, however, the mouse pointer doesn't track correctly when connecting to VNC. This is what I found out from looking at other reports of this problem. A hypervisor running Xen 4.0.1 with a 2.6.32-5-xen-amd64 doesn't seem to exhibit the same high CPU usage. I've also tried it on different set ups: - Xen 4.1.5 and 3.2.0-61-generic - Xen 4.1.6.1 and 3.2.0-51-generic Just wondering if anyone would have a solution for this issue. I did some research and it looks like quite a few people have come across this problem. I'm also not sure if this is the right place to be asking that, however, since I couldn't find any bug reports so I'm wondering if perhaps there is a solution to the high CPU usage or the mouse tracking over VNC. Any help or pointers as to how this could be solved would be appreciated.
