Recent rework of virshtest uncovered a subtle bug that was dormant in now vsh but before that even in monolithic virsh. In vsh.c there's this vshReadlineInit() function that's supposed to initialize readline library, i.e. set those global rl_* pointers. But it also initializes history library. Then, when virsh/virt-admin quits, vshReadlineDeinit() is called which writes history into a file (ensuring the parent directory exists). So far no problem. Problem arises when cmdComplete() is called (from a bash completer, for instance). It does not guard call to vshReadlineInit() with check for interactive shell (and it should not), but it sets ctl->historyfile which signals to vshReadlineDeinit() the history should be written. Now, no real history is written, because nothing was entered on the stdin, but the parent directory is created nevertheless. With recent movement in virshtest.c this means some test cases might create virsh history file which breaks our promise of not touching user's data in test suite.

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.
