I think this is a Fedora / systemd problem. apcupsd will detect the AC power failure and initiate a shutdown (shutdown -h -H now via apccontrol). But apccontrol killpower does not seem to be called. Also, during shutdown, systemd reports “A stop job is running for APC UPS Power Control Daemon for Linux”. Not sure if this is because the apcupsd service was what kicked off the shutdown command, so it wasn't able to be stopped.

Bug report filed: https://bugzilla.redhat.com/show_bug.cgi?id=1472062 Problem of not cutting UPS power seems to be due to /etc/apcupsd/powerfail file not getting created which might be because of SELinux. Other part of the problem (hanging on stopping the apcupsd service) still remains but is worked around by changing the service timeout to 10s.

• Install base F26 server.
• dnf update

• dnf install \
    vim \
    qemu-system-x86 \
    qemu-kvm \
    apcupsd \
    nfs-utils \
    libvirt-daemon-qemu \
    libvirt-client \
    ssmtp

• Edit /etc/default/grub:
  • Remove rhgb
  • Decrease timeout
• grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
• Add /etc/sysconfig/network-scripts/ifcfg-br0:

  DEVICE=br0
  TYPE=Bridge
  DELAY=0
  NM_CONTROLLED=no
  ONBOOT=yes
  BOOTPROTO=static
  IPADDR=192.168.16.20
  NETMASK=255.255.255.0
  GATEWAY=192.168.16.1

• In /etc/sysconfig/network-scripts/ifcfg-enp7s0, change BOOTPROTO to none, and add BRIDGE=br0 and NM_CONTROLLED=no
• chkconfig network on
• edit /etc/apcupsd/apcupsd.conf and /etc/apcupsd/apccontrol
• systemctl enable apcupsd.service
• systemctl enable libvirt-guests
• systemctl enable nfs-server.service
• systemctl enable rpcbind
• firewall-cmd –add-service=nfs –permanent
• Do fixes in https://bugzilla.redhat.com/show_bug.cgi?id=1472062 (disable SELinux and reduce stop timeout of apcupsd service to 10s) to allow apcupsd to work properly
• Configure ssmtp in /etc/ssmtp/ssmtp.conf
