Kvm Host configuration
Let's
start Installing the necessary packages on the host:
yum
install fence-virt fence-virtd
fence-virtd-libvirt fence-virtd-multicast
Then create the key needed for the host to
authenticate all the fencing requests from the guest cluster:
dd if=/dev/urandom of=/etc/cluster/fence_xvm.key bs=4096 count=1
The key
should then be copied to
/etc/cluster/fence_xvm.key of every guest.
Now run the configuration tool:
fence_virtd –c
service fence_virtd start
check your fence is working or not:
fence_xvm -o reboot –H node2
