Christian Ehrhardt 750e08443a virt-aa-helper: fix paths for usb hostdevs
If users only specified vendor&product (the common case) then parsing
the xml via virDomainHostdevSubsysUSBDefParseXML would only set these.
Bus and Device would much later be added when the devices are prepared
to be added.

Due to that a hot-add of a usb hostdev works as the device is prepared
and virt-aa-helper processes the new internal xml. But on an initial
guest start at the time virt-aa-helper renders the apparmor rules the
bus/device id's are not set yet:

p ctl->def->hostdevs[0]->source.subsys.u.usb
$12 = {autoAddress = false, bus = 0, device = 0, vendor = 1921, product
= 21888}

That causes rules to be wrong:
  "/dev/bus/usb/000/000" rw,

The fix calls virHostdevFindUSBDevice after reading the XML from
virt-aa-helper to only add apparmor rules for devices that could be found
and now are fully known to be able to write the rule correctly.

It uncondtionally sets virHostdevFindUSBDevice mandatory attribute as
adding an apparmor rule for a device not found makes no sense no matter
what startup policy it has set.

Build Status

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:

https://libvirt.org

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:
