* Config
** =/etc/libvirt/libvirtd.conf=
sudo vim /etc/libvirt/libvirtd.conf

find each of these in the file, or add them if they are not there:

#unix_sock_group = "libvirt"
#unix_sock_rw_perms = "0770"


#log_filters="1:qemu"
#log_outputs="1:file:/var/log/libvirt/libvirtd.log"

change to:

unix_sock_group = "libvirt"
unix_sock_rw_perms = "0770"

log_filters="1:qemu"
log_outputs="1:file:/var/log/libvirt/libvirtd.log"

if it is not in the file, simply add it. If it is not commented out with #, then just leave it as it is and exit the file.

Now run the following commands:

sudo usermod -a -G libvirt $(whoami)
sudo systemctl start libvirtd
sudo systemctl enable libvirtd


** QEMU configuration
edit:

sudo nano /etc/libvirt/qemu.conf

find:

#user = "root"
#group = "root"

change to:

user = "YOUR USERNAME"
group = "YOUR USERNAME"

Restart Libvirt:

sudo systemctl restart libvirtd

sudo usermod -a -G kvm "YOUR USERNAME" 
sudo usermod -a -G libvirt "YOUR USERNAME"

** Network Default Switch
sudo virsh net-autostart default
sudo virsh net-start default

** 성능향상팁
drive는 raw, virtio, cache  모드는 writeback
network => virtio
