Description Xiaodai Wang 2016-02-04 09:25:20 UTC

Description of problem:
Can't connect to any display if specifying nothing to monitor-mapping.

Version-Release number of selected component (if applicable):
virt-viewer-2.0-13.el6.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Set monitor-mapping to blank string.
# cat .config/virt-viewer/settings 

#rhel7.2-back-clone
[d622b6f8-fdee-ad9c-63fe-cac2e9b6200d]
monitor-mapping=
2. Wait for the guest startup and Login into the guest first.
3. lanuch virt-viewer with -f arguments.
# virt-viewer rhel7.2-back-clone -f


Actual results:

We already had this discussion, more than once, but why the tests are being done using root instead of a normal user? :-\

Hi, I tested this problem with root user and normal user. Both of them have same problem.

Comment 8 Xiaodai Wang 2016-03-07 07:23:52 UTC

Hi fidencio, 

For this bug, the empty value problem is resolved.

But if specify <CLIENT_MONITOR-ID> greater than the real monitor count, it still can't connect to any display. 

#rhel7.2-back-clone
[d622b6f8-fdee-ad9c-63fe-cac2e9b6200d]
monitor-mapping=1:5 

Should i file a new bug for it or just change the status of this bug? 

Thanks
