Configuration_Virt-Manager

Edit the following configurations:

sudo nano /etc/libvirt/libvirtd.conf

...
unix_sock_group = 'libvirt'
...
unix_sock_rw_perms = '0770'
...

sudo usermod -a -G libvirt $(whoami)

newgrp libvirt

sudo systemctl restart libvirtd.service

Edit the following configurations:

Add your user to /etc/libvirt/qemu.conf. Otherwise, QEMU will give a permission denied error when trying to access local drives.

Search for user = "libvirt-qemu" or group = "libvirt-qemu", uncomment both entries and change libvirt-qemu to your user name or ID. Once edited it should look something like below.

You can get your user by this command echo $USER or whoami, if you want to get user ID use this command id -u.

sudo nano /etc/libvirt/qemu.conf

# Some examples of valid values are:
#
#       user = "qemu"   # A user named "qemu"
#       user = "+0"     # Super user (uid=0)
#       user = "100"    # A user named "100" or a user with uid=100
#
user = "username"

# The group for QEMU processes run by the system instance. It can be
# specified in a similar way to user.
group = "username"
