hello Roger. thanks for the quick reply. I think, after a careful read of the xl.cfg man page plus a careful reading of the xen-tools source code, I've figured out the issue. I'm sending the solution here so folks will have it in the future. If one is configuring an hvm guest, any vfb specifications in the domain configuration are ignored. Instead, the parameters that normally get placed in a vfb stanza must be placed as top level configuration items. For example: For a PV guest: vfb = [ 'vnc=1,vnclisten=10.14.200.200' ] Translates to, for an hvm guest: vnc = 1 vnclisten = "10.14.200.200" The xl.cfg man page doesn't say that in order for the vnc parameters to be picked up for hvm guests with emulated graphics cards, those parameters need to be specified as top level parameters in the config file. It took reading the source code of the xen-tools xl code to figure that out. -thanks -Brian
