Re: where are the files ?

[Bob Power <b_power@xxxxxxxxx>]

Cheers Cole,

Turned out I hadn't got libvirt (et al) installed on the target. (discovered when I tried to use virsh)

Once I installed libvirt and restarted virt-manager they all showed up in the gui and seem to be working.

That was all under the default qemu:///system connection.

______

But now I try to add VMs that were under a qemu:///session connection ...

Try adding the connection and get:

------------------------

Unable to connect to libvirt qemu:///session.

Verify that the 'libvirtd' daemon is running.

Libvirt URI is: qemu:///session

I vaguely recall doing something relating to a user libvirt daemon but can't find it or see anything obvious on old machine (same libvirt daemons running on both)

Any ideas ?

virt-manager's connection list is stored in dconf. But it's probably not
worth trying to transfer that over, instead manually `File->Open
Connection` and recreate the list.

If once connected to local qemu:///system your VMs aren't showing up,
and you copied over /etc/libvirt/qemu files, you may need to restart
libvirtd or virtqemud (or reboot). The proper way to do this would have
been `sudo virsh dumpxml $VMNAME > $VMNAME.xml` on the source and then
`sudo virsh define $VMNAME.xml` on the dest.
