govc vm.create \
  -on=false \
  -m 16384 \
  -c 8 \
  -net 'VM Network' \
  -disk 120GB \
  -ds ose3-vmware \
  -folder /Boston/vm/rbohne \
  -g rhel9_64Guest \
  cp-{1,2}
..

for i in cp-{0,1,2} wp-{0,1}; do govc vm.change -vm /Boston/vm/rbohne/${i} -e disk.enableUUID=TRUE ;done

# Just for information
#for i in cp-{0,1,2} wp-{0,1}; do govc vm.power -off -force /Boston/vm/rbohne/${i} ;done
#for i in cp-{0,1,2} wp-{0,1}; do govc vm.power -on  /Boston/vm/rbohne/${i} ;done

openshift-install --dir vmw1/ agent create image

Start installation

Attach the agent iso to all VM's and boot it.

Watch the output of cp-0 as rendezvous host and the others.
