Again a reminder for me.
Copy from HP-UX VM Host following file to the guest machine and install the HPVM-Guest bundle.
vmhost# scp /opt/hpvm/guest-images/hpux/11iv3/hpvm_guest_depot.11iv3.sd root@vmguest:/tmp vmguest# swinstall -s /tmp/hpvm_guest_depot.11iv3.sd
Mark HPVM-Guest
Go to Actions -> Install…
Reboot !
