Package: qemu-kvm Version: 1.1.0+dfsg-3 Severity: grave When running libguestfs-test-tool (1:1.18.1-1), kvm hangs with 100% CPU utilization. Not being able to start a VM this makes libguestfs entirely useless.
Here are the last few lines that are printed to the terminal: libguestfs: accept_from_daemon: 0x7cda70 g->state = 1 [59760ms] /usr/bin/kvm \ -global virtio-blk-pci.scsi=off \ -nodefconfig \ -nodefaults \ -nographic \ -drive file=/tmp/libguestfs-test-tool-sda-vwjbCB,cache=off,format=raw,if=virtio \ -machine accel=kvm:tcg \ -m 500 \ -no-reboot \ -no-hpet \ -device virtio-serial \ -serial stdio \ -chardev socket,path=/tmp/libguestfsJJK8dE/guestfsd.sock,id=channel0 \ -device virtserialport,chardev=channel0,name=org.libguestfs.channel.0 \ -kernel /var/tmp/.guestfs-1000/kernel.13843 \ -initrd /var/tmp/.guestfs-1000/initrd.13843 \ -append 'panic=1 console=ttyS0 udevtimeout=300 no_timer_check acpi=off printk.time=1 cgroup_disable=memory selinux=0 guestfs_verbose=1 TERM=screen ' \ -drive file=/var/tmp/.guestfs-1000/root.13843,snapshot=on,if=virtio,cache=unsafe I have tried to reproduce this bug with several versions of qemu-kvm. Things work fine until 1.0+dfsg-11. It seems that the problem was introduced with the 1.1 prereleases. As the commandline contains the -nographic switch and options for setting up a virtio disk, this may be the same issue as reported with #680719. -Hilko -- Package-specific info:
