Description CongDong 2013-09-13 03:46:48 UTC

Description of problem:
Connect a guest with virt-viewer, and check on "Automatically resize"
item, but the effect is same with check off the item.
Whether the guest is spice or vnc, I tried both win7-64 and rhel6.4.

Version-Release number of selected component (if applicable):
# rpm -qa libvirt virt-viewer spice-gtk
virt-viewer-0.5.6-7.el6.x86_64
libvirt-0.10.2-24.el6.x86_64
spice-gtk-0.20-8.el6.x86_64

How reproducible:
100%

Steps to Reproduce:
1.Prepare a guest(spice or vnc are both ok), if use spice guest, stop service spice-vdagentd in guest.
2.# virt-viewer $guest, and check on the "Automatically resize" item.
3.Try to resize the virt-viewer window, and check the guest resolution.
4.Check off the "Automatically resize" item, and repeat step 3.

Actual results:
The result for step3 and step4 are the same, the display will match the current window*zoom size.

Expected results:
If check off the "Automatically resize" Item, the display should not match the current window*zoom size.

I don't really understand why you're stopping the vdagent service (step 1 in steps to reproduce).  If you stop the vdagent, it will not be possible to resize the guest display automatically.  Does it work properly when vdagent is running?

Hi:

That's what I'm not sure, what's the function of the auto-resize? 
It will change the resolution or the zoom level. So I stop the vdagent to check the zoom level.

1. If it reacts on the resolution for the guest, the spice guest is ok, but it doesn't work for the vnc guest.If it only for spice guest to auto-resize the resolution like you said, it's better to disabled the item for vnc guest.

2. If it reacts on the zoom level, I didn't find the difference wether I checked it on or off.

Comment 4 Jonathon Jongsma 2013-10-15 16:46:12 UTC

auto-resize only works for spice guests that have a vdagent.  When the client window is resized, it will attempt to update the resolution of the guest to match the resolution of the client window.  It does this by sending a message to the vdagent.

So the 'Automatically resize' menu item should probably be disabled for VNC and non-vdagent spice guests.

Comment 5 David Blechter 2013-10-15 18:58:59 UTC

running vd-agent is MUST for auto-resize feature to work, and it is for the spice only.
Closing as NOTABUG

Comment 6 Cui Lei 2013-10-16 03:10:39 UTC

Please consider the issue in comment3 descriptive:
"If it only for spice guest to auto-resize the resolution like you said, it's better to disabled the item for vnc guest."

As there is no related doc explain that, we should disable the item(make the item gray like 'USB device selection' in menu) in menu if it is useless in VNC display mode.

Comment 12 zhoujunqin 2014-06-05 09:37:39 UTC

I can reproduce this issue with:
virt-viewer-0.5.6-10.el6.x86_64

Verify this issue with virt-viewer-0.6.0-4.el6

step:
1.Prepare a guest(spice or vnc are both ok).
2.# virt-viewer $guest, then click menu "View", check "Automatically resize" item has been removed.

so change the status from 'ON_QA' to 'VERIFIED'.
