Hi, Somehow I'd expect such a nice graphical tool as virt.manager, that, if I can install, (and start the installed machine directly after install), stop, restore, and do all the other nice things with a xen vm, I must also be able to simply start a vm for which I have a config lying around.
But I see nowhere any "start a vm" option. The only thing that is there is a "restore vm" option, but when I chose a normal vm config file, it always says "error restring domain - is the domain already running". I assume, this function is really only for domains that I saved (not the same as opposed to shut down, at leat in xen terminology).
Is that right? Am I right that virt.manager has no functionality to simply start a vm with it's config file, and I must do this manually?

Hi Henning,
currently virt-manager does not offer a 'Start' option for VMs . virt-manager will provide full life-cycle support over time , including 'start' of VMs in a future release of virt-manager .
Right now you'll have to start a VM manually using "xm create (-c) VMname" . The "restore" option in virt-manager is part of the save/restore capabilities in virt-manager/Xen . Save/Restore allows you to save/snapshot a VM's memory footprint onto disk and 'restore/restart' the VM from this snapshot in the future.
Hth,
- Jan

Oh, I feared it being so (the only other possibility was it expecting me to place the config in a special place). That's really sad - it makes virt-manager look really incomplete - it's a small and probably very easy to implement function (for those who wrote the program and know i inside out), and something one is really missing and that makes the experience very inconsistent.
I mean, a VM even get's started after install - so it is really frustrating when searching and searching through the GUI and trying the restore button, and only after a long while coming up with the idea "hey, maybe this function is simply not implemented because it's alpha software" - which is easier for me to come up with than for many other people, cause I'm a software developer.

It is open source. Feel free to start adding that functionality.

I heard of the principle...
No, really - sorry when I sounded like I want to make somebody else implementing that feature for me! Actually I am testing these things cause I want to write something about them - I myself am happy with the command line, and therefore won't get engaged in this project, but I'd like to recommend some GUI apps for people who want it.
And I'd be happy to be able to write that virt-manager is a complete tool that not only let's you install and stop a vm, but even start one :)

The problem is ultimately in XenD itself - the RPC protocol used for managing VMs has no spport for inactive guests - the 'xm' command line tool has this functionality hardcoded in itself so its not exposed to other tools via the API. The new Xen 3.0.4 released 2 weeks ago does now have inactive guest support, so Xen in Fedora 7 will likely support this.
For the Xen 3.0.3 in Fedora Core 6, we have had to write some extra code in libvirt to manage inactive domains by bypassing XenD. This was just pushed to Fedora updates in libvirt 0.1.10 a few days back. Thus I will now be able to enable support for inactive domains in the next release of virt-manager - hopefully within the next couple of weeks.
So, yes, you are right that there is no way to start an existing guest using virt-manager in Fedora today. We are actively implemnenting this so expect it to appear in the near future....
Regards, Dan.
