Virt-Manager Configuration

Installation

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

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"

sudo virsh net-autostart default sudo virsh net-start default

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