Description of problem: every single VM guest(different OSes) slows down to the level it becomes useless boot to 2.6.35.10-74.fc14.x86_64 and all goes back to normal is it only us? Version-Release number of selected component (if applicable): qemu 0.13.0-1 How reproducible: one of the VMs qemu-kvm -localtime -m 14336 -smp cores=4 -vga std -drive file=win7-64-70GB-A.img,index=0,media=disk -net tap,name=tap,vlan=0,ifname=tap0,script=no,downscript=no -net nic,macaddr=52:54:00:12:34:73,model=e1000 -vnc 192.168.0.141:8 -monitor tcp::5907,server,nowait,nodelay Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
Is it only happening with Windows 7? What kind of processor does that machine have? (Please attach the contents of /proc/cpuinfo from the host.)

I'm afraid can not do any time soon, but as soon as I get a chance I'll get back with any results.
I think default repository package does not have this problem, albeit -mtune=native might not necessary be the problem with my installation, I had it with vde2 libs/functionality recompiled. I'll try again -mtune but without vde2. regards
