I commented out the ovm_set_password and ovm_configure_network steps in /u01/scripts/db-reconfig.sh since I had manually set up a static IP on my guest. (Note: this script no longer bothers checking for or setting up oracleasm so you don't need to worry about that). I also uncommented the DEBUG_PSFT_OVM variable in the /opt/oracle/psft/vm/oraclevm-template-utils.sh script. Doing this bypasses the root password reset and networking configuration in the oraclevm-template.sh script.
/dev/sdb1 /u01 ext3 defaults 1 3 /dev/sdc1 /opt/oracle/psft/ptdb ext3 defaults 1 4 /dev/sdd1 /opt/oracle/psft/pt ext3 defaults 1 5
(Just a note on the beauty of VirtualBox: I didn't figure out all the above in a single step. But by taking some snapshots of my virtual machine I was able to go back and start over with a minimum of fuss.)
