There are currently broken use cases, e.g. snapshotting more than one disk at once like: $ virsh snapshot-create-as --domain eoan --disk-only --atomic --diskspec vda,snapshot=no --diskspec vdb,snapshot=no --diskspec vdc,file=/test/disk1.snapshot1.qcow,snapshot=external --diskspec vdd,file=/test/disk2.snapshot1.qcow,snapshot=external The command above will iterate from qemuDomainSnapshotCreateDiskActive and eventually add /test/disk1.snapshot1.qcow first (appears in the rules) to then later add /test/disk2.snapshot1.qcow and while doing so throwing away the former rule causing it to fail. All other calls to (re)load_profile already use append=true when adding rules append=false is only used when restoring rules [1]. Fix this by letting AppArmorSetSecurityImageLabel use append=true as well. Since this is removing a (unintentional) trigger to revoke all rules appended so far we agreed on review to do some tests, but in the tests no rules came back on: - hot-plug - hot-unplug - snapshotting Bugs: https://bugs.launchpad.net/libvirt/+bug/1845506 https://bugzilla.redhat.com/show_bug.cgi?id=1746684 [1]: https://bugs.launchpad.net/libvirt/+bug/1845506/comments/13 Reviewed-by: Cole Robinson <crobinso@redhat.com> Acked-by: Jamie Strandboge <jamie@canonical.com> Signed-off-by: Christian Ehrhardt <christian.ehrhardt@canonical.com>
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

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, however, we mandate to have the build directory different than the source directory. For example, to build in a manner that is suitable for installing as root, use:
$ mkdir build && cd build
$ ../configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
$ make
$ sudo make install
While to build & install as an unprivileged user
$ mkdir build && cd build
$ ../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:
