Introduction[edit]
Qubes-Whonix ™ users require some extra instructions for setting up AppArmor.
AppArmor[edit]
The following steps should be completed in dom0 for both whonix-gw-15 and whonix-ws-15 TemplateVMs. [1] After these settings are 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.[2] It is also important to verify AppArmor is active in the sys-whonix and anon-whonix VMs after making these changes.
Whonix-Gateway ™[edit]
1. Open a dom0 terminal.
Qubes App Launcher (blue/grey "Q") → System Tools → Xfce Terminal
2. List the current kernel parameters.
qvm-prefs -g whonix-gw-15 kernelopts
Qubes R4 and later releases will show.
nopat
3. Keep the existing kernel parameters and add apparmor=1 security=apparmor.
For example.
qvm-prefs -s whonix-gw-15 kernelopts "nopat apparmor=1 security=apparmor"
qvm-prefs -s sys-whonix kernelopts "nopat apparmor=1 security=apparmor"
4. 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-15 kernelopts
The output should show AppArmor is part of the new kernel parameters. For example.
nopat apparmor=1 security=apparmor
5. Start the sys-whonix ProxyVM and confirm AppArmor is now active.
sudo aa-status --enabled ; echo $?
The output should show.

Whonix-Workstation ™[edit]
1. Open a dom0 terminal.
Qubes App Launcher (blue/grey "Q") → System Tools → Xfce Terminal
2. List the current kernel parameters.
qvm-prefs -g whonix-ws-15 kernelopts
Qubes R4 and later releases will show.
nopat
3. Keep the existing kernel parameters and add apparmor=1 security=apparmor.
For example.
qvm-prefs -s whonix-ws-15 kernelopts "nopat apparmor=1 security=apparmor"
qvm-prefs -s anon-whonix kernelopts "nopat apparmor=1 security=apparmor"
4. 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-15 kernelopts
The output should show AppArmor is part of the new kernel parameters. For example.
nopat apparmor=1 security=apparmor
5. Start the anon-whonix AppVM and confirm AppArmor is now active.
sudo aa-status --enabled ; echo $?
The output should show.

Debugging[edit]
If you see any of the following messages that means the instructions above have not been applied.
sudo systemctl status apparmor

Footnotes[edit]
- ↑
While Debian has enabled AppArmor by default since the
busterrelease, Fedora has not. This matters since Qubes, which is Fedora based, by default uses thedom0(not VM) kernel. Therefore this is still required even though Whonix ™ is based on a recent enough Debian version. - ↑ Since Qubes R3.0, TemplateBasedVMs inherit the kernelopts setting of their TemplateVM [archive].
