I'm trying to use the ESX driver to extract metadata from ESX in an easily digestible form for driving V2V. I've noticed the domain XML seems to be missing a few bits:
<features/>
This is currently not implemented, but could be by parsing the CPUIDs. This is on my todo list.
This would be extremely useful.
<graphics/>
VMware seems to use a certain type of VNC for this, but they use a custom authentication mechanism. There is a Firefox plugin for that (vmware-mks.xpi), but IIRC its Windows only. I think this could be implemented but there is more research necessary what to expose as graphics element.
<input/>
A ESX virtual machine has a PS2 mouse and keyboard by default and AFAIK that's not changeable. So the ESX driver could output input elements for them, but the user won't be able to change it when defining a new virtual machine. Currently input elements are ignored by the ESX driver.
To explain my use case, I'm using the domain XML provided by the ESX driver to form the basis of domain XML for the QEMU driver. I don't need to be able to modify or even access the underlying guest, I just need to know that the devices exist and what drivers they are using. I believe there is more than 1 available graphics device in ESX, so that would be most important.
<serial/> and <console/> are also missing, but that could well be because they aren't present.
By default a virtual machine doesn't have serial/parallel ports, but you can add them and the ESX driver will output the serial/parallel elements for them. The console element is automatically deduced by libvirt from the first serial port in the domain XML config, the ESX driver has not influence here.
Ok. I can add these in explicitly. Thanks, Matt -- Matthew Booth, RHCA, RHCSS Red Hat Engineering, Virtualisation Team M: +44 (0)7977 267231 GPG ID: D33C3490 GPG FPR: 3733 612D 2D05 5458 8A8A 1600 3441 EA19 D33C 3490
