The way our bash completion string is that is gets user's input
and lets virsh completion code do all the work by calling 'virsh
complete -- $INPUT". The 'complete' command is a "secret",
unlisted command that exists solely for this purpose. After it
has done it's part, it prints candidates onto stdout, each
candidate on its own line, e.g. like this:
# virsh complete -- "net-u"
net-undefine
net-update
net-uuid
These strings are then stored into a bash array $A like this:
A=($($1 ${CMDLINE} complete -- "${INPUT[@]}" 2>/dev/null))
This array is then thrown back at bash completion to produce
desired output. So far so good. Except, when there is an option
with space. For instance:
# virsh complete -- start --domain ""
uefi\ duplicate
uefi
Bash interprets that as another array item because by default,
Internal Field Separator (IFS) = set of characters that bash uses
to split words at, is: space, TAB, newline. We don't want space
nor TAB. Therefore, we have to set $IFS when storing 'virsh
complete' output into the array.
Thanks to Peter who suggested it.

Libvirt API for virtualization
==============================
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
For some of these hypervisors, it provides a stateful management
daemon which runs on the virtualization host allowing access to the
API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other
languages including Python, Perl, PHP, Go, Java, OCaml, as well as
mappings into object systems such as GObject, CIM and SNMP.
