Pending commissioning (libvirt)

Hello,

i’ve installed maas 3.2 on Ubuntu 20.04, localhost. Now i am trying to finish this lesson from docs. I 've made everything in the same way like in the lesson, but after adding VM the commissioning process is pending for a long time.

I cannot understand, what i am doing wrong.

P.S. here is screenshot of adding new VM in maas.
