libvirt users - Dec 2015 - libvirt list --all shows empty list after restart

Hi all,
   I think I might have a small configuration issue: after restarting my
machine, all the VMs previously installed are not available.

virsh list --all shows an empty list.
The .img files where the VMs were intalled are present in the folder I put
them in. Furthermore if I import the VMs (virt-install -import) it all
seems to work. It's just that I don't want to have to do this after
every
restart and can't find where libvirt picks up information about any
existing VMs on the system.

Thanks,
Andrei

1) Are you running virsh as root?

2) How did you create the guests? Did you use virt-install or virsh 
define? Or maybe you're using "virsh create"? (the latter would
create a
transient guest, whose configuration would exist only until the guest 
was terminated).

It all depends on whether or not you were running as root when you 
created the guests. If you were running as root, virsh/virt-install 
would have connected to qemu:///system, and the config for the guest is 
stored in /etc/libvirt/qemu. If you were running as an unprivileged 
user, virsh/virt-install would connect to qemu:///session (an instance 
of libvirtd specific to the current user), and the configuration for the 
guests would be in ~/.config/libvirt/qemu.

Note that you should *never* directly examine or modify these files, as 
their existence is not a part of the official libvirt API; you should 
instead use virsh, virt-manager, or some other management application 
that uses the libvirt API. I am only telling you this information so 
that you can do a sanity check on the files' existence/location.
