Hello there,
I just mess with qemu/kvm using virtual manager. During set up a VM I have following error.

Also as can you see on the last screenshot my NAT is inactive.
Anybody can help?

Ok guys problem solved....almost.
Let's see all the procedure.

First of all I create a group named kvm
Code:
sudo groupadd kvm
and then I installed all the below packages
Code:
sudo apt install bridge-utils libvirt-bin qemu-kvm qemu-system

Next, make the root user and the kvm group the owner of the /var/lib/libvirt/images directory
Code:
sudo chown root:kvm /var/lib/libvirt/images
and also change the permition of the above file
Code:
sudo chmod g+rw /var/lib/libvirt/images
and I add my account to kvm group
Code:
sudo usermod -aG kvm charis
After all that I start the service
Code:
sudo systemctl start libvirtd
and check it's status
Code:
sudo systemctl status libvirtd
Once service is active and running I install some additional packages
Code:
sudo apt install ssh-askpass virt-manager
Last but no least I made some changes to the /etc/libvirt/libvirtd.conf file
Firstly I copy the original
Code:
sudo cp /etc/libvirt/libvirtd.conf /etc/libvirt/libvirtd.conf.orig
and then I change below lines
#unix_sock_group = "libvirtd"
to the following
#unix_sock_group = "kvm"
and this line
#unix_sock_ro_perms = "0777"
changed it to this:
#unix_sock_ro_perms = "0770"
and restart the serive
Code:
sudo systemctl restart libvirtd
Here I have to say that all the above are as per Jay LaCroix guide.

So once I tried to set up my first VM I had the above error as I mentioned on the first post.

Googling around I realised that the above packages were not enough for run qemu/kvm
So I also installed
Code:
sudo apt install uml-utilities
but didn't work for me, then I install
Code:
sudo apt install qemu-utils
But still the issue exist.

Next step I installed
Code:
sudo apt install ebtables && sudo apt install dnsmasqd
...and Miraculous issue solved but a new one came up

Code:
Error connecting to graphical console:
Error opening Spice console, SpiceClientGtk missing
Still googling I found that I have to download the below package
Code:
gir1.2-spiceclientgtk-3.0
This solve my last problem and finally I can set up my first VM
Now my VM can not connect to the internet, I am still searching for a solution, if anybody can help is welcome.
I hope the above guide to be helpful to anybody.
