# prereqs:
# 1) a) this script b) the modules (vmmon, vmblock, vmnet) match the
#    installed vmware/player version (ensured by stage1 install)
# 2) the script is tailored to the vendor-os we are running
# 3) the script checks a configuration file to know which modes to
#    prepare
# 4) we use the dhcp-server for ALL internal interfaces we are running
# 5) stage3 produces a configfile /etc/vmware/slxvmconfig where the
#    settings of networking etc. are made

# read the configuration file generated in stage3 to configure the
# host internal interfaces
. /etc/vmware/slxvmconfig
