Description Dan Kenigsberg 2014-07-23 16:24:25 UTC
+++ This bug was initially created as a clone of Bug #988070 +++

Description of problem:
A simple description of a emulated PPC64 in a domain XML doesn't create a virtual keyboard.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Use virsh to create a domain based on the attached vm.xml file
2. Wait until the Open Firmware command prompt opens up
3. You cannot interact with the prompt since there is no virtual keyboard

Actual results:
It is not possible to write anything in the Open Firmware prompt.

Expected results:
There should be a way to interact with the Open Firmware prompt or create a virtual keyboard in the domain XML.

Additional info:
I haven't found a way to create a virtual USB keyboard through the libvirt, instead i used the "qemu:commandline" tag to pass the "-usbdevice keyboard" parameter to QEMU.

this bug won't fit into 3.5 release and is being deferred to a later release. If you deeply care about this bug and deserves to be re-evaluated please let me know

Comment 2 Michal Skrivanek 2015-06-05 13:19:33 UTC
still want to consider this "soon"

Comment 6 Red Hat Bugzilla Rules Engine 2015-10-18 08:33:45 UTC
Bug tickets that are moved to testing must have target release set to make sure tester knows what to test. Please set the correct target release before moving to ON_QA.

Hi Can you please provide with clear steps to reproduce and verify?
I'm not sure what behaviour to look for here.

Comment 8 Martin Polednik 2015-12-10 12:59:36 UTC
This bug is about not adding specific hacks to the XML. If you create VM on VDSM without fix applied, you would see something like

    <qemu:arg value='-usbdevice'/>
    <qemu:arg value='keyboard'/>

whereas VDSM with the fix applied will omit this. Can be verified from libvirt via virsh (virsh -r dumpxmpl <domain_name or domain_id>).

Comment 9 sefi litmanovich 2015-12-10 13:18:59 UTC
Verified with rhevm-

OS Version:
RHEL - 7.2 - 9.el7_2.1
Kernel Version:
3.10.0 - 327.2.1.el7.ppc64le
KVM Version:
2.3.0 - 31.el7_2.4
LIBVIRT Version:
VDSM Version:

1. Created a Power guest vm from an existing tempalte.
2. started vm.
3. vm xml doesn't include the mouse/keyboard usb device under the qemu cmdline tag, but does include the expected tags:

    <input type='keyboard' bus='usb'>
      <alias name='input0'/>
    <input type='mouse' bus='usb'>
      <alias name='input1'/>

Comment 10 Sandro Bonazzola 2015-12-22 13:27:43 UTC
