Fedora 19 to 21 Upgrade

After performing the upgrade, the dhcp and dns server are not functional.

To verify if the service is functional do the following from a command line:

 sudo systemctl status dnsmasq.service

If its not working you will get a message similar to below with a failed status:

dnsmasq.service - DNS caching server.

Loaded: loaded (/usr/lib/systemd/system/dnsmasq.service; enabled)

Active: failed (Result: exit-code) since Tue 2015-09-08 10:38:40 MST; 6s ago

Process: 7798 ExecStart=/usr/sbin/dnsmasq -k (code=exited, status=2)

Main PID: 7798 (code=exited, status=2)

During the upgrade libvirtd was installed. libvirtd uses dnsmasq for virtual machines. This caused a conflict. To verify this is the issue do the following commands:

 sudo lsof -i :53

COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME

dnsmasq 1308 nobody 6u IPv4 20640 0t0 UDP localhost.localdomain:domain

dnsmasq 1308 nobody 7u IPv4 20641 0t0 TCP localhost.localdomain:domain (LISTEN)

 ps -ef| grep <number in bold above>

nobody 1308 1 0 10:04 ? 00:00:00 /sbin/dnsmasq --conf-file=/var/lib/libvirt/dnsmasq/default.conf --dhcp-script=/usr/libexec/libvirt_leaseshelper

root 1309 1308 0 10:04 ? 00:00:00 /sbin/dnsmasq --conf-file=/var/lib/libvirt/dnsmasq/default.conf --dhcp-script=/usr/libexec/libvirt_leaseshelper

if you see something like --conf-file=/var/lib/libvirt/dnsmasq/default.conf then you can fix the dnsmasq problem by issuing the following command and then rebooting.

 sudo systemctl disable libvirtd

 sudo reboot
