I have just instaled virt-manager on Arch Linux, I've gone through all of the steps of creating a VM, but when I click on "Finish" on step 5/5 I get two pop-up dialogs:
Unable to complete install: 'Requested operation is not valid: network 'default' is not active'
Details:

I saw that is said "package not installed" after virbr0, so I tried:
$ sudo pacman -Syu virbr0 - not found
$ yay -Syu virbr0 - also not found
