My Ubuntu is : 20.04 LTS, and I using libvirtd on it to manage KVM vm, but now I can not open listener function of the libvirtd.
SYSTEM SOCKET ACTIVATION
The libvirtd daemon is capable of starting in two modes.
In the traditional mode, it will create and listen on UNIX sockets itself. If the --listen parameter is given, it will also listen on TCP/IP socket(s),
according to the listen_tcp and listen_tls options in /etc/libvirt/libvirtd.conf
In socket activation mode, it will rely on systemd to create and listen on the UNIX, and optionally TCP/IP, sockets and pass them as pre-opened file de�\
scriptors. In this mode, it is not permitted to pass the --listen parameter, and most of the socket related config options in /etc/libvirt/libvirtd.conf
will no longer have any effect. To enable TCP or TLS sockets use either
$ systemctl start libvirtd-tls.socket
$ systemctl start libvirtd-tcp.socket
But, on my system, there are no such service like libvirtd-tls.socket or libvirtd-tcp.socket.
root ubts1:~# systemctl | grep libvirt
libvirt-guests.service loaded active exited Suspend/Resume Running libvirt Guests
libvirtd.service loaded active running Virtualization daemon
libvirtd-admin.socket loaded active running Libvirt admin socket
libvirtd-ro.socket loaded active running Libvirt local read-only socket
libvirtd.socket loaded active running Libvirt local socket
How can I open the listener ?
