4.6 VNC Console Fails on Oracle VM Server

The VNC console works for hardware virtualized (HVM) machines. For all other types (paravirtualized (PV), and hardware virtualized with paravirtualized drivers (PVHVM)), the VNC console fails to correctly display for virtual machines on Oracle VM Server. The console is blank (black). The serial console is not affected.

Workaround: Set the virtual machine image to be of type HVM, then boot a virtual machine from the amended image. You can use either Glance or Nova to change the image property. For example, using Nova:

$ nova image-meta img-uuid set vm_mode=hvm 

Or using Glance:

$ glance image-update img-uuid --property vm_mode=hvm
