The following script (for starting the seed VM) fails to execute completely. It terminates with the error message "libvirt.libvirtError: internal error: Unable to determine model for scsi controller".

HP_VM_MODE=y bash -x ~root/tripleo/tripleo-incubator/scripts/ --create seed

I am using the latest download available from the wesite.

  1. enable virtualization support in the bios
  2. Install cpu-checker sudo apt-get update sudo apt-get install cpu-checker
  3. checkity check sudo kvm-ok
  4. If enabled you'd get INFO: /dev/kvm exists KVM acceleration can be used
  5. If not enabled you'd get INFO: /dev/kvm does not exist INFO: blah blah

I saw this same error with Ubuntu 14.04 and

root@seednode:~# cat tripleo/HP_Helion_Version 
jenkins-installer-build-corvallis-ee-1.0-hlinux-ironic-13: Sun Sep 28 11:43:14 PDT 2014

Changing to Ubuntu 13.10 fixed it.

I heard there was a OpenvSwitch problem with 14.04. This could well be fixed in a more recent Helion version.
