Red Hat Bugzilla – Bug 357491
[5.2] <Shift> + <Tab> is unusable keyboard shortcut for HVM guest domain
Last modified: 2009-09-02 05:48:49 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):
virt-manager (changeset 637)
virt-viewr (changeset 16)
Steps to Reproduce:
1. Create a HVM guest domain
2. Open the guest domain by using virt-manager or virt-viewer
I cannot move the focus by <Shift> + <Tab>
I can move the focus by <Shift> + <Tab>
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
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 ?

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.
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>.
<Shift><Tab> do not work.
The focus move to previous place when <Shift> + <Tab> pressed.
<Shift><Tab> works when the physical machines connected by vncviewer.
There was a regression in the fix upstream. Fixed it again with
