Qubes/AppArmor
From Whonix
< Qubes
Qubes-Whonix ™ users require some extra instructions for setting up AppArmor.
If you are interested, click on Expand on the right.
The following steps should be completed in dom0 for both whonix-gw-14 and whonix-ws-14 TemplateVMs. After these settings have been applied to the Whonix templates, the sys-whonix (ProxyVM) and anon-whonix (AppVM) will inherit the AppArmor kernel settings.
It is unnecessary to recreate the sys-whonix and anon-whonix TemplateBasedVMs to benefit from the new kernel parameters.[1] It is also important for users to verify AppArmor is active in the sys-whonix and anon-whonix VMs after making these changes.
Whonix-Gateway ™[edit]
Open a dom0 terminal.
Qubes App Launcher (blue/grey "Q") → System Tools → Xfce Terminal
List the current kernel parameters.
qvm-prefs -g whonix-gw-14 kernelopts
Qubes R3.2 and later releases will show.
nopat
Keep the existing kernel parameters and add 'apparmor=1 security=apparmor'. For example.
qvm-prefs -s whonix-gw-14 kernelopts "nopat apparmor=1 security=apparmor"
qvm-prefs -s sys-whonix kernelopts "nopat apparmor=1 security=apparmor"
List the current kernel parameters again (hit the up arrow key twice; it is unnecessary to type the command again).
qvm-prefs -g whonix-gw-14 kernelopts
The output should show AppArmor is part of the new kernel parameters. For example.
nopat apparmor=1 security=apparmor
Start the sys-whonix ProxyVM and confirm AppArmor is now active.
sudo aa-status --enabled ; echo $?
The output should show.

Whonix-Workstation ™[edit]
Open a dom0 terminal.
Qubes App Launcher (blue/grey "Q") → System Tools → Xfce Terminal
List the current kernel parameters.
qvm-prefs -g whonix-ws-14 kernelopts
Qubes R3.2 and later releases will show.
nopat
Keep the existing kernel parameters and add 'apparmor=1 security=apparmor'. For example.
qvm-prefs -s whonix-ws-14 kernelopts "nopat apparmor=1 security=apparmor"
qvm-prefs -s anon-whonix kernelopts "nopat apparmor=1 security=apparmor"
List the current kernel parameters again (hit the up arrow key twice; it is unnecessary to type the command again).
qvm-prefs -g whonix-ws-14 kernelopts
The output should show AppArmor is part of the new kernel parameters. For example.
nopat apparmor=1 security=apparmor
Start the anon-whonix AppVM and confirm AppArmor is now active.
sudo aa-status --enabled ; echo $?
The output should show.
