I have been following this link https://help.ubuntu.com/community/KVM/Installation to install KVM on Ubuntu 18.04.1 LTS. But I cannot start it properly and encounter the following errors.
$ virsh list --all
error: failed to connect to the hypervisor
error: Failed to connect socket to '/var/run/libvirt/libvirt-sock':
No such file or directory
The directory /var/run/libvirt/libvirt-sock
indeed does not contain libvirt-sock
$ ls /var/run/libvirt
network storage virtlockd-sock virtlogd-sock
What are the solutions to this issue? and how can I install KVM properly? Many Thanks
