Can’t find the network manager, sys-net doesn’t work

qvm-pci give me :
Failed to list 'pci devices, this device type either does not existor you do not have acces to it.

both in user and root

lspci can replace qvm-pci ?

and i got unregonize arguments when i change sys-usb in sys-net… I think i misspelled the command

Try:
qvm-pci list

same message

I suggest you file a github issue for this.

thank you… i appreciate @Quser59

For the first time in my life I’ve seen Devices tab greyed out. Is it greyed out in any other qube? Something is very bad here.

It’s probably greyed out for a running qube. You can’t attach or detach devices to/from a running qube.
