What will happen when the input tag of the xml has the following format ? <input type != 'mouse/tablet' bus != 'xen/usb/ps2'/> For ein on Xen_PointingDevice Should the caption be "Unknown bus Unknown device type" ?? Though I tried creating a guest with invalid values in the input tags using the xml file, the guest was always created with the <input type='mouse' bus='xen'/> tag when I saw the dumpxml of the guest. Is there a way to supply invalid values to the input tag ?

So setting the caption to > "Unknown bus Unknown device type" is a fall back in that case. Does the <input type='mouse' bus='xen'/> get assigned by default ? Because, for Xen PV the values are getting assigned by default even though the tc did not supply them . Ex: check the vsxml output from the tc 41_cs_to_settingdefinestate.py. The default values are not getting assigned for KVM though.

Thanks and Regards, Deepti.

So setting the caption to > "Unknown bus Unknown device type" is a fall back in that case. What should be the values for Xen, XenFV, KVM and LXC for input type and bus tags ? Should we supply input type='mouse' bus='xen' for XenPV by default? when to supply type=tablet and bus=ps2/usb ?

KR> LXC: type: mouse bus: usb Eh? Does libvirt put a mouse device into the LXC config? If it does, it's a bug.
