Package: python-guestfs Version: 1:1.32.7-1+b2 Severity: important I've been developing scripts using python-guestfs to create a new image, with a single partition and ext2 filesystem, then adding files from a tar before unmounting. This has been working flawlessly until the update in unstable today:

The script just takes a .tar and unpacks it.) QEMU itself appears to continue working for running virtual machines (including machines created using this same script before the update). I've tried restarting the libvirtd-daemon and libvirt-guest services, no effect. The same process is being used in lava-dispatcher to run tests using QEMU - test jobs now fail when the current version of python-guestfs is combined with qemu 2.7 in the same place, creating a filesystem for the test, before the test files themselves are actually loaded. python-guestfs fails with: ii qemu-system-x86 1:2.7+dfsg-1 Downgrading qemu to the version in testing fixes the problems: ii qemu-system-x86 1:2.6+dfsg-3.1 -- System Information: Debian Release: stretch/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386, armhf, arm64 Kernel: Linux 4.7.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=en_GB.utf8, LC_CTYPE=en_GB.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages python-guestfs depends on: ii libc6 2.24-3 ii libguestfs0 1:1.32.7-1+b2 ii python 2.7.11-2 pn python:any <none> python-guestfs recommends no packages. python-guestfs suggests no packages. -- no debconf information -- Neil Williams ============= http://www.linux.codehelp.co.uk/
