how do I start libvirtd on community-gtk?
Your question is vague so i assume you've met the error where virt-manager doesn't connect after starting the service. Try to run it as root: sudo virt-manager
To check the status of the libvirtd service you have for instance on OpenRC: rc-service libvirtd status
when i do "rc-service libvirtd status" it says "*rc-service: service 'libvirtd' does not exist" while, libvirtd is downloaded, also, i didn't start libvirtd because i don't know how to start it, as it just fails when i try to do the start command.
Please confirm that you have package 'libvirt-openrc' installed.
libvirt-openrc was not installed that's why it didn't work, thanks alot for the help.
