Well, well, well… What a fuckup! As of this writing [2016-03-03] the current versions of the Archlinux Kernel and libvirtd are not working at all. Took me almost a week to figure this out.<\/p>\n

There are two issues:<\/p>\n

    \n
  1. The Kernel package 4.4.1-2-ARCH (which is actually 4.4.3 with patches) crashes silently if you try to start a VM from libvirtd (if you even get so far, but that’s covered below). Honestly, I have no idea why, because it doesn’t sputter an OOPS. What I know: Downgrading to 4.3.3-3-ARCH fixes that issue.<\/li>\n
  2. libvirt-1.3.2-1 is broken, or rather libvirtd.service is… It says that libvirtd is of type notify. That may be true, but it doesn’t work. Don’t even bother to fiddle around with polkit rules: It doesn’t work. IMHO polkit is over-engineered.<\/li>\n<\/ol>\n

    To fix (1.): Downgrade the Kernel to 4.3.3. If you don’t have a copy, download it here<\/a>. Install it with:<\/p>\n

    # pacman -U linux-4.3.3-3-x86_64.pkg.tar.xz\r\n# systemctl reboot<\/pre>\n
    When the older kernel is running (confirm it with uname -a), we can fix (2.) by turning libvirtd.service from Type=notify to Type=simple. Be warned<\/strong>: It may have serious side effects! You’re on your own when you do this!<\/p>\n
    # cp \/usr\/lib\/systemd\/system\/libvirtd.service \/etc\/systemd\/system<\/pre>\n
    Now edit \/etc\/systemd\/system\/libvirtd.service and comment out Type=notify. This turns\u00a0libvirtd into a “simple” service, not forking, no authentication, nothing. Then reload everything and start libvirtd, virtlockd and virtlogd:<\/p>\n
    # systemctl daemon-reload\r\n# systemctl start libvirtd virtlockd virtlogd<\/pre>\n
    Finally (re-)start your virtual machines. Share and enjoy!<\/p>\n","protected":false},"excerpt":{"rendered":"
