Description Ulrich Drepper 2006-11-14 15:18:51 UTC

Description of problem:
I installed a domain using the command line tools.  When I want to use that
domain now with virt-manager I cannot use the graphical console/framebuffer
since the 'use_graphics' xenstore variableis set to "0" and there is no obvious
way to change this.

Version-Release number of selected component (if applicable):
virt-manager-0.2.3-2.fc6.x86_64

How reproducible:
always

Steps to Reproduce:
1.install doman with virt-install
2.start domain with virt-managet
3.
  
Actual results:
no graphical console

Expected results:
graphical can be enabled

Additional info:
virt-manager should allow we to select the graphical console.  It should change
the xenstore setting before starting the domain.

This bug should probably be duplicated for FC7 and RHEL and made a blocker for
RHEL5.

Comment 1 Ulrich Drepper 2006-11-14 15:38:57 UTC

I should clarify this a bit.  A more fundamantal problem is that I cannot start
a domain which exists as a config file in /etc/xen in virt-manager.  If this
could be added, maybe virt-manager would set the variable.

But so far I have to create the domain with xm create and then it seems already
to be too late for virt-manager to do its magic.

So, maybe the solution is to add a way to virt-manager to start a domain like xm
create but also set the magic configuration options to create the graphical console.

Yes, virt-manager is unable to manage inactive domains - since XenD provides no
API for enumerating them at this time. We are tracking work to add support for
inactive domains in bug 210648

To get the graphical console working it needs to be enabled at the time you
start the guest domain. For virt-install either use the '--vnc'  command line
arg, or say 'yes' when asked to enable graphics. For an existing domain, edit
the config file in /etc/xen  and add

vnc=1
vncunused=1

and then re-start the guest - graphics should now be possible.


virt-manager itself is unable to manage inactive domains - since XenD provides
no API for enumerating them at this time, thus it has no way to enable graphics
- this hsa to be done when the domain is started. We are tracking work to add
support for inactive domains in bug 210648

This capability is now available in upstream source repo. Will make its way into
Fedora next time we sync up for an update.
