Description of problem: Yesterday through APT system I updated qemu-kvm package to version: 1.1.0+dfsg-3 Since then, with KVM module loaded, the GuestFS launch routine hangs indefinitely. Running libguestfs-test-tool doen not prodce any relevant output, it just hangs until the timeout expires with the CPU 100% loaded on kvm process. Unloading the KVM kernel module solves it. Reverting to old qemu-kvm package solves it. With prior qemu-kvm version everything worked fine. Here's libguestfs-test-tool output: ===== Test starts here ===== TMPDIR=(not set) library version: 1.18.1 guestfs_get_append: (null) guestfs_get_attach_method: appliance guestfs_get_autosync: 1 guestfs_get_direct: 0 guestfs_get_memsize: 500 guestfs_get_network: 0 guestfs_get_path: /usr/lib/guestfs guestfs_get_pgroup: 0 guestfs_get_qemu: /usr/bin/kvm guestfs_get_recovery_proc: 1 guestfs_get_selinux: 0 guestfs_get_smp: 1 guestfs_get_trace: 0 guestfs_get_verbose: 1 host_cpu: x86_64 Launching appliance, timeout set to 300 seconds. libguestfs: [00000ms] febootstrap-supermin-helper --verbose -f checksum '/usr/lib/guestfs/supermin.d' x86_64 supermin helper [00000ms] whitelist = (not specified), host_cpu = x86_64, kernel = (null), initrd = (null), appliance = (null) supermin helper [00000ms] inputs[0] = /usr/lib/guestfs/supermin.d checking modpath /lib/modules/3.2.0-3-amd64 is a directory picked vmlinuz-3.2.0-3-amd64 because modpath /lib/modules/3.2.0-3-amd64 exists checking modpath /lib/modules/3.2.0-2-amd64 is a directory picked vmlinuz-3.2.0-2-amd64 because modpath /lib/modules/3.2.0-2-amd64 exists supermin helper [00000ms] finished creating kernel supermin helper [00000ms] visiting /usr/lib/guestfs/supermin.d supermin helper [00000ms] visiting /usr/lib/guestfs/supermin.d/base.img supermin helper [00000ms] visiting /usr/lib/guestfs/supermin.d/daemon.img supermin helper [00000ms] visiting /usr/lib/guestfs/supermin.d/hostfiles supermin helper [00019ms] visiting /usr/lib/guestfs/supermin.d/init.img supermin helper [00019ms] adding kernel modules supermin helper [00120ms] finished creating appliance libguestfs: [00122ms] begin building supermin appliance libguestfs: [00122ms] run febootstrap-supermin-helper libguestfs: [00122ms] febootstrap-supermin-helper --verbose -f ext2 /usr/lib/guestfs/supermin.d x86_64 /var/tmp/guestfs.EypUUV/kernel /var/tmp/guestfs.EypUUV/initrd /var/tmp/guestfs.EypUUV/root supermin helper [00000ms] whitelist = (not specified), host_cpu = x86_64, kernel = /var/tmp/guestfs.EypUUV/kernel, initrd = /var/tmp/guestfs.EypUUV/initrd, appliance = /var/tmp/guestfs.EypUUV/root supermin helper [00000ms] inputs[0] = /usr/lib/guestfs/supermin.d checking modpath /lib/modules/3.2.0-3-amd64 is a directory picked vmlinuz-3.2.0-3-amd64 because modpath /lib/modules/3.2.0-3-amd64 exists checking modpath /lib/modules/3.2.0-2-amd64 is a directory picked vmlinuz-3.2.0-2-amd64 because modpath /lib/modules/3.2.0-2-amd64 exists supermin helper [00000ms] finished creating kernel supermin helper [01208ms] finished mke2fs supermin helper [01209ms] visiting /usr/lib/guestfs/supermin.d supermin helper [01209ms] visiting /usr/lib/guestfs/supermin.d/base.img supermin helper [01268ms] visiting /usr/lib/guestfs/supermin.d/daemon.img supermin helper [01272ms] visiting /usr/lib/guestfs/supermin.d/hostfiles supermin helper [03614ms] visiting /usr/lib/guestfs/supermin.d/init.img supermin helper [03615ms] adding kernel modules supermin helper [08757ms] closing ext2 filesystem supermin helper [08758ms] finished creating appliance libguestfs: [08882ms] finished building supermin appliance libguestfs: [08883ms] begin testing qemu features libguestfs: [08905ms] finished testing qemu features libguestfs: accept_from_daemon: 0x97e3e0 g->state = 1 [08906ms] /usr/bin/kvm \ -global virtio-blk-pci.scsi=off \ -nodefconfig \ -nodefaults \ -nographic \ -drive file=/tmp/libguestfs-test-tool-sda-qtS2hu,format=raw,if=virtio \ -machine accel=kvm:tcg \ -m 500 \ -no-reboot \ -no-hpet \ -device virtio-serial \ -serial stdio \ -chardev socket,path=/tmp/libguestfsIGmBWH/guestfsd.sock,id=channel0 \ -device virtserialport,chardev=channel0,name=org.libguestfs.channel.0 \ -kernel /var/tmp/.guestfs-1000/kernel.8202 \ -initrd /var/tmp/.guestfs-1000/initrd.8202 \ -append 'panic=1 console=ttyS0 udevtimeout=300 no_timer_check acpi=off printk.time=1 cgroup_disable=memory selinux=0 guestfs_verbose=1 TERM=xterm ' \ -drive file=/var/tmp/.guestfs-1000/root.8202,snapshot=on,if=virtio,cache=unsafeAlarm clock Version-Release number of selected component (if applicable): 1.18.1-1 How reproducible: Install latest Debian Wheezy version of qemu-kvm Make sure that both kvm and kvm_intel modules are loaded into the kernel Run libguestfs-test-tool or guestfs_launch() routine.
I'd suspect the problem is qemu. In Fedora we add fixes to whatever qemu upstream spits out (which is usually broken). See our git repo here: http://pkgs.fedoraproject.org/cgit/qemu.git/
I have libguestfs working on Wheezy now. However you need to apply some patches, and there are other bugs. See: https://www.redhat.com/archives/libguestfs/2012-November/msg00024.html
Problem seems to be fixed with newer version of qemu (now in Debian Experimental 1.4.0). Libguestfs 1.20 from Sid seems to be broken with both qemu versions (Wheezy qemu 1.1.2 Experimental qemu 1.4.0) Here the libguestfs-test-tools output: ************************************************************ * IMPORTANT NOTICE * * When reporting bugs, include the COMPLETE, UNEDITED * output below in your bug report. * ************************************************************ ===== Test starts here ===== PATH=/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games library version: 1.20.1 guestfs_get_append: (null) guestfs_get_attach_method: appliance guestfs_get_autosync: 1 guestfs_get_cachedir: /var/tmp guestfs_get_direct: 0 guestfs_get_memsize: 500 guestfs_get_network: 0 guestfs_get_path: /usr/lib/guestfs guestfs_get_pgroup: 0 guestfs_get_qemu: /usr/bin/kvm guestfs_get_recovery_proc: 1 guestfs_get_selinux: 0 guestfs_get_smp: 1 guestfs_get_tmpdir: /tmp guestfs_get_trace: 0 guestfs_get_verbose: 1 host_cpu: x86_64 Launching appliance, timeout set to 600 seconds. libguestfs: command: run: febootstrap-supermin-helper libguestfs: command: run: \ --verbose libguestfs: command: run: \ -f checksum libguestfs: command: run: \ /usr/lib/guestfs/supermin.d libguestfs: command: run: \ x86_64 supermin helper [00000ms] whitelist = (not specified), host_cpu = x86_64, kernel = (null), initrd = (null), appliance = (null) supermin helper [00000ms] inputs[0] = /usr/lib/guestfs/supermin.d checking modpath /lib/modules/3.2.0-4-amd64 is a directory picked vmlinuz-3.2.0-4-amd64 because modpath /lib/modules/3.2.0-4-amd64 exists checking modpath /lib/modules/3.2.0-3-amd64 is a directory picked vmlinuz-3.2.0-3-amd64 because modpath /lib/modules/3.2.0-3-amd64 exists supermin helper [00000ms] finished creating kernel supermin helper [00001ms] visiting /usr/lib/guestfs/supermin.d supermin helper [00001ms] visiting /usr/lib/guestfs/supermin.d/base.img supermin helper [00001ms] visiting /usr/lib/guestfs/supermin.d/daemon.img supermin helper [00001ms] visiting /usr/lib/guestfs/supermin.d/hostfiles supermin helper [00088ms] visiting /usr/lib/guestfs/supermin.d/init.img supermin helper [00089ms] adding kernel modules supermin helper [00318ms] finished creating appliance libguestfs: checksum of existing appliance: 01b9595383c436b3904827c906396be2abd5b73a7e7c8a9957703e752fa1f5c6 libguestfs: [00324ms] begin building supermin appliance libguestfs: [00325ms] run febootstrap-supermin-helper libguestfs: command: run: febootstrap-supermin-helper libguestfs: command: run: \ --verbose libguestfs: command: run: \ --copy-kernel libguestfs: command: run: \ -f ext2 libguestfs: command: run: \ /usr/lib/guestfs/supermin.d libguestfs: command: run: \ x86_64 libguestfs: command: run: \ /var/tmp/guestfs.IBkG3L/kernel libguestfs: command: run: \ /var/tmp/guestfs.IBkG3L/initrd libguestfs: command: run: \ /var/tmp/guestfs.IBkG3L/root febootstrap-supermin-helper: unrecognized option '--copy-kernel' febootstrap-supermin-helper: build the supermin appliance on the fly Usage: febootstrap-supermin-helper [-options] inputs [...] host_cpu kernel initrd febootstrap-supermin-helper -f ext2 inputs [...] host_cpu kernel initrd appliance febootstrap-supermin-helper -f checksum inputs [...] host_cpu febootstrap-supermin-helper --help febootstrap-supermin-helper --version This script is used by febootstrap to build the supermin appliance (kernel and initrd output files).

Forgot to mention: KVM is not enabled as I'm running qemu with Debian inside Virtualbox, shouldn't be relevant but just to be more complete :)
Comments 3 & 4 aren't related to the original bug. (In reply to comment #3) > febootstrap-supermin-helper: unrecognized option '--copy-kernel' This means that febootstrap is too old. Version 3.21 is required, 3.20 won't work.
shall I close this bug and open a new one? I've updated febootstrap fron Debian Sid, the result is that it hangs: ************************************************************ * IMPORTANT NOTICE * * When reporting bugs, include the COMPLETE, UNEDITED * output below in your bug report. * ************************************************************ ===== Test starts here ===== PATH=/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games library version: 1.20.1 guestfs_get_append: (null) guestfs_get_attach_method: appliance guestfs_get_autosync: 1 guestfs_get_cachedir: /var/tmp guestfs_get_direct: 0 guestfs_get_memsize: 500 guestfs_get_network: 0 guestfs_get_path: /usr/lib/guestfs guestfs_get_pgroup: 0 guestfs_get_qemu: /usr/bin/kvm guestfs_get_recovery_proc: 1 guestfs_get_selinux: 0 guestfs_get_smp: 1 guestfs_get_tmpdir: /tmp guestfs_get_trace: 0 guestfs_get_verbose: 1 host_cpu: x86_64 Launching appliance, timeout set to 600 seconds. libguestfs: command: run: febootstrap-supermin-helper libguestfs: command: run: \ --verbose libguestfs: command: run: \ -f checksum libguestfs: command: run: \ /usr/lib/guestfs/supermin.d libguestfs: command: run: \ x86_64 supermin helper [00000ms] whitelist = (not specified), host_cpu = x86_64, kernel = (null), initrd = (null), appliance = (null) supermin helper [00000ms] inputs[0] = /usr/lib/guestfs/supermin.d checking modpath /lib/modules/3.2.0-4-amd64 is a directory picked vmlinuz-3.2.0-4-amd64 because modpath /lib/modules/3.2.0-4-amd64 exists checking modpath /lib/modules/3.2.0-3-amd64 is a directory picked vmlinuz-3.2.0-3-amd64 because modpath /lib/modules/3.2.0-3-amd64 exists supermin helper [00000ms] finished creating kernel supermin helper [00001ms] visiting /usr/lib/guestfs/supermin.d supermin helper [00001ms] visiting /usr/lib/guestfs/supermin.d/base.img supermin helper [00002ms] visiting /usr/lib/guestfs/supermin.d/daemon.img supermin helper [00002ms] visiting /usr/lib/guestfs/supermin.d/hostfiles supermin helper [00173ms] visiting /usr/lib/guestfs/supermin.d/init.img supermin helper [00174ms] adding kernel modules supermin helper [00294ms] finished creating appliance libguestfs: checksum of existing appliance: 5865a5198d5acc0cfb09e5d71f71d4767e5e081b5cbc936e47180d8dab2c90f8 libguestfs: [00302ms] begin testing qemu features libguestfs: command: run: /usr/bin/kvm libguestfs: command: run: \ -nographic libguestfs: command: run: \ -help W: kvm binary is deprecated, please use qemu-system-x86_64 instead libguestfs: command: run: /usr/bin/kvm libguestfs: command: run: \ -nographic libguestfs: command: run: \ -version W: kvm binary is deprecated, please use qemu-system-x86_64 instead libguestfs: qemu version 1.4 libguestfs: command: run: /usr/bin/kvm libguestfs: command: run: \ -nographic libguestfs: command: run: \ -machine accel=kvm:tcg libguestfs: command: run: \ -device ? libguestfs: [00643ms] finished testing qemu features libguestfs: accept_from_daemon: 0x1bd24d0 g->state = 1 [00646ms] /usr/bin/kvm \ -global virtio-blk-pci.scsi=off \ -nodefconfig \ -nodefaults \ -nographic \ -device virtio-scsi-pci,id=scsi \ -drive file=/tmp/libguestfs-test-tool-sda-u3EL1u,cache=none,format=raw,id=hd0,if=none \ -device scsi-hd,drive=hd0 \ -drive file=/var/tmp/.guestfs-1000/root.9953,snapshot=on,id=appliance,if=none,cache=unsafe \ -device scsi-hd,drive=appliance \ -machine accel=kvm:tcg \ -m 500 \ -no-reboot \ -no-hpet \ -device virtio-serial \ -serial stdio \ -device sga \ -chardev socket,path=/tmp/libguestfsLD0ec6/guestfsd.sock,id=channel0 \ -device virtserialport,chardev=channel0,name=org.libguestfs.channel.0 \ -kernel /var/tmp/.guestfs-1000/kernel.9953 \ -initrd /var/tmp/.guestfs-1000/initrd.9953 \ -append 'panic=1 console=ttyS0 udevtimeout=600 no_timer_check acpi=off printk.time=1 cgroup_disable=memory root=/dev/sdb selinux=0 guestfs_verbose=1 TERM=xterm'W: kvm binary is deprecated, please use qemu-system-x86_64 instead Could not access KVM kernel module: No such file or directory failed to initialize KVM: No such file or directory Back to tcg accelerator.

Please open new bugs for new issues. If they are duplicate we will mark them as such.
Closing, since all the issues are fixed if you follow the instructions here: https://www.redhat.com/archives/libguestfs/2012-November/msg00024.html This can't be fixed in libguestfs -- it needs Debian packaging fixes.
