I would suspect that the devices aren't up. These directories come and go as
the devices are up'ed and down'ed.
Do you see these devices with IP numbers in the output of `ifconfig`

VIP's are independant of each other. If you setup lo:110 to carry
the VIP=192.168.1.110 by doing
ifconfig lo:110 192.168.1.110 netmask $NETMASK ...
then for VIP=192.168.1.111 you'll do
ifconfig lo:111 192.168.1.111 ...

lo is for LVS-DR, tunl0 is for LVS-Tun.
You can use ip to set them up, but for simple setups ifconfig/route
is simpler. Once you have it working, you can use ip.
