[SOLVED] libvirtd 5.6.0 not listening on TCP socket

I just updated and pulled in libvirtd 5.6.0. I run libvirtd with a TCP listening socket. For some reason the tcp listening socket does not bind; however, if I run libvirtd in debug mode on the command-line it works fine. Anybody know what is going on?

Not working via systemd

Re: [SOLVED] libvirtd 5.6.0 not listening on TCP socket

Figured it out. libvirtd-tcp.socket is missing from the install.

/usr/lib/systemd/system/libvirtd-tcp.socket should exist

[Unit]
Description=Libvirt non-TLS IP socket
Before=libvirtd.service
BindsTo=libvirtd.socket
After=libvirtd.socket

[Socket]
# This must match the @sysconfdir@/libvirt/@service@.conf tcp_port setting
# when using systemd version < 227
ListenStream=16509
Service=libvirtd.service

[Install]
WantedBy=sockets.target

Re: [SOLVED] libvirtd 5.6.0 not listening on TCP socket

pacman -Fo /usr/lib/systemd/system/libvirtd-tcp.socket
usr/lib/systemd/system/libvirtd-tcp.socket is owned by community/libvirt 5.6.0-1

Filesystem corruption?
