Apps and Virtualization

Hello, recently I’ve tried to install VM on 27.0.0-RC.1
No matter what options I do select , whether i try to install linux or windows I always get :
[EFAULT] internal error: cannot load AppArmor profile ‘libvirt-e3f3ad28-b55a-4f2e-bb52-6cdd3d77301c’

Full error is :

Error Name: EFAULT

Any help more than welcomed :slight_smile:

What is VM?

3

Virtual Machine

4

Actually, I think @shoulders was asking what settings you were using for the VM in question. In particular, was this a pre-25 VM that had been migrated into incus, or was this one built in the VM UI?

5

Fresh using native UI. Nothing significant :
Linux (Tried also setting it as windows with windows defaults) , 1 CPU , 2 Cores , 1 Thread PC, Ram Max 2GB Min 256MB , 20 GB drive (fresh) , connected through bridged NIC

Details of your hardware, please. Do you have VT-x enabled in your BIOS?

Problem seems to be solved by usual routine - I’ve restarted TrueNas and now everything works.
Thank you @Samuel_Tai for these questions. :slight_smile: Otherwise I probably would be stuck for longer not thinking about routine “have you tried to …”
