Hello,
I'm running libvirt 3.1.0 on a Debian 8 server. I installed apparmor and configured
libvirt to use apparmor as security driver.
After booting a VM, virsh dumpxml shows an apparmor seclabel.
As soon as I try to attach a second disk to the VM, apparmor blocks this.
virsh attach-device test-vps /tmp/virshXmlDefinition
error: Failed to attach device from /tmp/virshXmlDefinition
error: operation failed: Could not open '/mnt/images/disk2.raw': Permission
denied
Syslogs shows me the following:
Mar 22 17:45:20 vps0 kernel: [1136647.318314] audit: type=1400 audit(1490201120.577:30):

In the VM specific apparmor file
/etc/apparmor.d/libvirt/libvirt-5747e4db-a3b7-fd69-ca89-00007b0bf859.files I see:
"/mnt/images/disk1.raw" rw,
Which is my primary VM disk, I expected a virsh attach-device to append
/mnt/images/disk2.raw to this file and reload/refresh the apparmor profile?
I'm not able to attach a live disk to a running VM with apparmor. Am I missing
something? Or is this a bug/missing feature in libvirt?
Thanks,
Frank
