Hi Serge, I haven't experienced the same behavior as before 100% CPU with latest qemu-kvm. However, during installation of a natty VM, while doing IO, the CPU load is still a bit high sometimes ~70-80%. But, overall I can't seem to reproduce this problem. The kvm command used by libvirt now is:
/usr/bin/kvm -S -M pc-0.14 -enable-kvm -m 512 -smp 2,sockets=2,cores=1,threads=1 -name natty3 -uuid a1fc02e8-0002-f0fd-f292-a0afa52500b3 -nodefconfig -nodefaults -chardev socket,id=monitor,path=/var/lib/libvirt/qemu/natty3.monitor,server,nowait -mon chardev=monitor,mode=readline -rtc base=utc -no-reboot -boot dc -drive file=/var/lib/libvirt/images/natty3.img,if=none,id=drive-virtio- disk0,boot=on,format=raw -device virtio-blk-pci,bus=pci.0,addr=0x5,drive =drive-virtio-disk0,id=virtio-disk0 -drive file=/home/roaksoax/Desktop /ubuntu_natty-server-i386.iso,if=none,media=cdrom,id=drive- ide0-1-0,readonly=on,format=raw -device ide-drive,bus=ide.1,unit=0,drive =drive-ide0-1-0,id=ide0-1-0 -netdev tap,fd=43,id=hostnet0 -device virtio-net- pci,netdev=hostnet0,id=net0,mac=52:54:00:38:54:4d,bus=pci.0,addr=0x3 -chardev pty,id=serial0 -device isa-serial,chardev=serial0 -usb -vnc 127.0.0.1:1 -vga cirrus -device AC97,id=sound0,bus=pci.0,addr=0x4 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x6 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/716528 Title: kvm 100% when performing apparently IO operations -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
