Comment 5 for bug 1801918

This is again a case of please read all characters carefully :-)

definition from xml:
(gdb) p def->source.devices[i].path
$4 = 0x7f5204008e30 "/dev/disk/by-path/virtio-pci-0000:00:07.0"

compared against the array it built with the lvm tools
(gdb) p thisSource->devices[0]
$7 = {nfreeExtent = 0, freeExtents = 0x0, path = 0x7f51fc012b20 "/dev/disk/by-path/pci-0000:00:07.0", format = 0, part_separator = 0, geometry = {cylinders = 0, heads = 0, sectors = 0}}

That is different:
/dev/disk/by-path/virtio-pci-0000:00:07.0
/dev/disk/by-path/pci-0000:00:07.0

Lets further improve the lvm config we have.
