How to disable AppArmor using Libvirt in Ubuntu

Libvirt is blocked by Apparmor when doing something. Therefore, to ensure that Libvirt always has the required permissions, you must disable apparmor. The method is as follows:

1. Select the -- without-apparmor option when compiling libvirt;

2. Run the following command to disable apparmor for libvirt:

$ Ln-s/etc/apparmor. d/usr. sbin. lib+d/etc/apparmor. d/disable/

$ Ln-s/etc/apparmor. d/usr. lib. libvirt. virt-aa-helper/etc/apparmor. d/disable/

$ Apparmor_parser-R/etc/apparmor. d/usr. sbin. lib1_d

$ Apparmor_parser-R/etc/apparmor. d/usr. lib. libvirt. virt-aa-helper

Then restart the machine.
