Description Saori Fukuta 2007-10-29 20:12:16 EDT
Description of problem:
  To control the focus, I want to use keyboard shortcuts.
  But <Shift> + <Tab> is unusable for HVM guest domain on the viewer of 
  virt-manager, <Tab> is usable though.
  virt-viewer has the same result.
  This problem does not occur with PV domain.

Version-Release number of selected component (if applicable):
  from RPM (RHEL5.1 RC):
    kernel-xen (kernel-xen-2.6.18-52.el5)
    xen (xen-3.0.3-41.el5)
  from cvs:
    virt-manager (changeset 637)
    virt-viewr (changeset 16)

How reproducible:

Steps to Reproduce:
  1. Create a HVM guest domain
  2. Open the guest domain by using virt-manager or virt-viewer
Actual results:
  I cannot move the focus by <Shift> + <Tab>

Expected results:
  I can move the focus by <Shift> + <Tab>

Additional info:
  If there is other unusable keyboard shortcut, I will report it here.

This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release.  Product Management has requested
further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products.  This request is not yet committed for inclusion in an Update
Comment 3 Tatsuro Enokura 2007-11-02 03:03:46 EDT
I think that the cause of this problem is not virt-viewer or gtk-vnc,
occurred by another module.

Let me tell you why I thought.
I debugged how the value of "keyvalue" was set at gtk_vnc
(gdk_keymap_translate_keyboard_state() in key_event() at vncdisplay.c), 
and I compared the result of them:
   shortcut       Domain           keyvalue      
   <Shift><TAB>   HVM (unusable)   ISO_Left_Tab  
   <Shift><TAB>   PV  (usable)     ISO_Left_Tab  
But the setting value is same between HVM and PV.

Do you have any idea ?

Comment 4 RHEL Product and Program Management 2008-03-11 15:38:20 EDT
This request was previously evaluated by Red Hat Product Management
for inclusion in the current Red Hat Enterprise Linux release, but
Red Hat was unable to resolve it in time.  This request will be
reviewed for a future Red Hat Enterprise Linux release.

Comment 13 Mark Xie 2009-07-05 12:55:29 EDT
This issue still occur on X86-64 platform, <Shift> + <Tab> do not work in the application of the guest. Both virt-manager and virt-viewer have this issue, and it can be repoduced on all KVM, xen FV, xen PV base guest.

Package version:

1, Open a KVM, xen FV or Xen PV guest.
2, Connect to it by virt-manager or virt-viewer.
3, Open a application or system configure utility, try the <Shift><Tab>.

Actual Results:
<Shift><Tab> do not work.

Expect Results:
The focus move to previous place when <Shift> + <Tab> pressed.

Additional info:
<Shift><Tab> works when the physical machines connected by vncviewer.
