Peter Krempa 105bcdde76 qemu: hotplug: Fix detach of disk with managed persistent reservations
In commit 8bebb2b735d I've refactored how the detach of disk with a
managed persistent reservations object is handled. After the commit if
any disk with a managed PR object would be removed libvirt would also
attempt to remove the shared 'pr-manager-helper' object potentially used
by other disks.

Thankfully this should not have practical impact as qemu should reject
deletion of the object if it was still used and the rest of the code is
correct.

Fix this by removing the disk from the definition earlier and checking
if the shared/managed pr-manager-helper object is still needed.

This basically splits the detach code for the managed PR object from the
unmanaged ones. The same separation will follow for the attachment code
as well as it greatly simplifies -blockdev support for this.

Build Status CII Best Practices

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.

Further information about the libvirt project can be found on the website:

License

The libvirt C API is distributed under the terms of GNU Lesser General Public License, version 2.1 (or later). Some parts of the code that are not part of the C library may have the more restrictive GNU General Public License, version 2.1 (or later). See the files COPYING.LESSER and COPYING for full license terms & conditions.

Installation

Libvirt uses the GNU Autotools build system, so in general can be built and installed with the usual commands. For example, to build in a manner that is suitable for installing as root, use:

$ ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
$ make
$ sudo make install

While to build & install as an unprivileged user

$ ./configure --prefix=$HOME/usr
$ make
$ make install

The libvirt code relies on a large number of 3rd party libraries. These will be detected during execution of the configure script and a summary printed which lists any missing (optional) dependencies.

Contributing

The libvirt project welcomes contributions in many ways. For most components the best way to contribute is to send patches to the primary development mailing list. Further guidance on this can be found on the website:
