Fix for this issue is the same as BZ#912926. Please, verify. I encountered the same problem: WinXP guest became so slowly after installing virtio netkvm driver.Almost can not install HCK client. How reproducible: 5 times Step to Reproduce: 1.usr/libexec/qemu-kvm -m 2G -smp 2 -cpu cpu64-rhel6,+x2apic -usb -device usb-tablet -drive file=winxp-0724.raw,if=none,id=drive-ide0-0-0,werror=stop,rerror=stop,cache=none -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 -netdev tap,sndbuf=0,id=hostnet0,vhost=on,script=/etc/qemu-ifup-private,downscript=no -device virtio-net-pci,netdev=hostnet0,mac=00:12:24:2a:3e:23,bus=pci.0,addr=0x4,id=virtio-net-pci0 -netdev tap,sndbuf=0,id=hostnet2,script=/etc/qemu-ifup,downscript=no -device rtl8139,netdev=hostnet2,mac=00:31:a3:33:e2:4a,bus=pci.0,addr=0x6 -uuid 5bd58aae-e261-4e41-8a96-8ad12901bbc5 -no-kvm-pit-reinjection -chardev socket,id=111a,path=/tmp/monitor-winxp-32-nic1,server,nowait -mon chardev=111a,mode=readline -spice port=5931,disable-ticketing -vga qxl -name winxp-32-s2-60-HCK -rtc base=localtime,clock=host,driftfix=slew -global PIIX4_PM.disable_s3=0 -global PIIX4_PM.disable_s4=0 2.install netkvm driver download from http://download.devel.redhat.com/brewroot/work/tasks/4727/5744727/virtio-win-prewhql-0.1.zip 3.Change computer name and add domain env. 4.restart and install HCK client Actual results: After restarting, can not use mouse. It took much more time than before. Expected results: mouse is ok. Don't take much time as usual. Packages:
