I have got the next error information after try run a QEMU/KVM virtual machine on Virt-Manager:
Error al iniciar dominio: internal error: child reported: Kernel does not provide mount namespace: Permiso denegado 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 1080, in create if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) libvirtError: internal error: child reported: Kernel does not provide mount namespace: Permiso denegado
I have no problem 2 days ago. Maybe it is due a kernel upgrade?
