[Klug-general] QEMU and Ubuntu 18.04 apparmor error

[Paul Littlefield]

Hello Folks,

I cannot create or start any QEMU virtual machines on my laptop. It was fine up until a week or so ago.

The error is:-


"Error starting domain: internal error: cannot load AppArmor profile 'libvirt-a5d9e3c8-6557-4efc-b7e1-836216e22ed7'

Traceback (most recent call last):
   File "/usr/share/virt-manager/virtManager/asyncjob.py", line 89, in cb_wrapper
     callback(asyncjob, *args, **kwargs)
   File "/usr/share/virt-manager/virtManager/asyncjob.py", line 125, in tmpcb
     callback(*args, **kwargs)
   File "/usr/share/virt-manager/virtManager/libvirtobject.py", line 82, in newfn
     ret = fn(self, *args, **kwargs)
   File "/usr/share/virt-manager/virtManager/domain.py", line 1508, in startup
     self._backend.create()
   File "/usr/lib/python2.7/dist-packages/libvirt.py", line 1062, in create
     if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)
libvirtError: internal error: cannot load AppArmor profile 'libvirt-a5d9e3c8-6557-4efc-b7e1-836216e22ed7'"


Web searching reveals it points to 'apparmor' and a missing configuration file placed in the directory /etc/apparmor.d/libvirt/ but I cannot find any mention of setting this up.

I am right up to date with my Ubuntu system and have reinstalled the software again and rebooted.

$ sudo apt-get install --reinstall apparmor qemu-kvm libvirt-bin bridge-utils virtinst

I am still searching but any help would be appreciated.

Ubuntu 18.04 LTS
QEMU 2.11+dfsg-1ubuntu7.4
Python 2.7.15rc1
AppArmor 2.12-4ubuntu5

Cheers,

:-)
