I see this error since today. Even stopping apparmor, then tearing down all profiles, trying to start a kvm host gives:
root@vh01:~# service apparmor stop * Clearing AppArmor profiles cache [ OK ] All profile caches have been cleared, but no profiles have been unloaded. Unloading profiles will leave already running processes permanently unconfined, which can lead to unexpected situations. To set a process to complain mode, use the command line tool 'aa-complain'. To really tear down all profiles, run the init script with the 'teardown' option." root@vh01:~# service apparmor teardown * Unloading AppArmor profiles [ OK ] root@vh01:~# virsh start ns1 error: Failed to start domain ns1 error: internal error Process exited while reading console log output: chardev: opening backend "pty" failed Looks like this is related to latest apparmor updates, but these do not fix the error. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libvirt in ubuntu. https://bugs.launchpad.net/bugs/632696 Title: libvirt won't start a VM with serial or console when apparmor is enabled -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
