Fedora xen - Mar 2007 - Problem about creating virtual machine in FC6

Hi,

I installed FC6 and I was trying to create a new virtual machine with the
virtual machine manager. I selected to use FC6 again as the guesting OS of
the new virtual machine.

Everytime after I finishing install of the guest OS, It gave me a prompt
to reboot the guest system. But After I click the "reboot" button, the
vitual machine gone. It''s weird. I think the reboot shouldn''t
make the
guest OS crash.

I use the /var/lib/xen/images/box1 as the storage space of the guest OS. I
found that the file box1 is still there. So I was trying to use the
"restore saved machine" of virtual machine manager to reload it,
However
it said that "Error restoring domain
''/var/lib/xen/images/box1''. Is the
domain already running?"

SO I use the "xm list" to show all domains, only domain0 is there.

Anybody knows how to fix the above problem? Why did the newly created
virtual machine disappeared whenever I rebooted it? How to make it
won''t
disapper? Or how to load it into system again?

Regards,
Angel

"restore saved machine" is to restore machine which is saved using 
Virtual Machine -> save, not to start vms which are shut down.
As of now, virt-manager is only capable of managing active/running vms. 
Managing inactive domains using virt-manager is something for future... 
You sould use "xm crate <config file name>" to boot a
machine.

libvirt in FC6 does now have support for starting & listing inactive
domains. You can list them with

    virsh  list --all      or  virsh list --inactive

Start them with

    virsh start  <name|uuid>

Delete an inactive config with

    virsh undefine <name|uuid>

And finally create a new inactive domain from an XML description

    virsh define <xml file>

Once its had more tsting I''ll push out an update virt-manager which can
managed them too - this is already in F7 rawhide.

Dan.
