Doc Text:	Virtual machine connection options in the event of a non-responsive rhev-agent have changed. Previously the virtual machine showed an error and canceled the SPICE connection. Now, a confirmation dialog box appears, warning the user that the virtual machine will have reduced capabilities because the agent is non-responsive. The user may select to run the virtual machine anyway, or cancel. If the user continues, the SPICE console will be opened without SSO.	Story Points:	---

Description Idith Tal-Kohen 2012-12-13 15:58:59 UTC

+++ This bug was initially created as a clone of Bug #871083 +++

Description of problem:
Allow connection to the guest with non-responsive agent.

The current behaviour is a workaround for spicec limitation that when agent-related feature was requested from it, it stalled until it established communication with agent. Spice-gtk-based clients are more fault-tolerant in this respect so this hard limitation of User Portal could safely be turned to soft one ("Agent is not responsive. Some features may not work. [cancel] [connect anyway]").


Version-Release number of selected component (if applicable):
si19.1 / 3.1.0-18

How reproducible:
always

Steps to Reproduce:
1. have a Windows VM with tools (mainly virtio-serial, rhev-agent and spice-vdagent running)
2. stop rhev-agent service
3. wait a while
4. try to connect to the VM again
  
Actual results:
you get this message:
Error while executing action VmLogon: Guest agent non-responsive
[close]

Expected results:
you get either dismissable warning (as outlined above; preferable solution) or no warning at all.

warning dialog on spice connection to guest with non responsive agent

Simon - is the dialog in the attached picture seems ok? (if the user press cancel, the spice console connection is aborted, and if the user press ok the spice console is opened without logon)

What happens if the tools are not installed in the first place? does the pop-up shows or do we connect anyhow? If it is the same then please change the first line.

Could not connect to the agent on the guest, it may be unresponsive or not installed.  

You can drop the third line, it's clear that the action is proceed or abort. 


We also need the option ignore that message for good, but this is part of the persistent session issues or the VM configuration.
