I'm trying to bring up a VM through virsh define, virsh start. The command doesn't show any errors and virsh list shows the VM is running. However, I can't access to the console, so I checked the libvirt log.
There are a few errors reporting:
virStorageFileBackendFileRead Failed to open file '/dev/...': Permission denied
The /dev/s are the logical volumes that I created. I already use root as user so I'm not sure what caused the permission error.
I saw this thread and it says this is related to apparmor. I tried to disable apparmor with systemctl disable apparmor but the permission error still remains. Any help would be appreciated.
