Laine Stump e62cb4a9b7 conf: move 'generated' member from virMacAddr to virDomainNetDef Commit `7e62c4cd26` (first appearing in libvirt-3.9.0 as a resolution to rhbz #1343919) added a "generated" attribute to virMacAddr that was set whenever a mac address was auto-generated by libvirt. This knowledge was used in a single place - when trying to match a NetDef from the Domain to Delete with user-provided XML. Since the XML parser always auto-generates a MAC address for NetDefs when none is provided, it was previously impossible to make a search where the MAC address isn't significant, but the addition of the "generated" attribute made it possible for the search function to ignore auto-generated MACs. This implementation had a problem though - it was adding a field to a "low level" struct - virMacAddr - which is used in other places with the assumption that it contains exactly a 6 byte MAC address and nothing else. In particular, virNWFilterSnoopEthHdr uses virMacAddr as part of the definition of an ethernet packet header, whose layout must of course match an actual ethernet packet. Adding the extra bools into virNWFilterSnoopEthHdr caused the nwfilter driver's "IP discovery via DHCP packet snooping" functionality to mysteriously stop working. In order to fix that behavior, and prevent potential future similar odd behavior, this patch moves the "generated" member out of virMacAddr (so that it is again really is just a MAC address) into virDomainNetDef, and sets it only when virDomainNetGenerateMAC() is called from virDomainNetDefParseXML() (which is the only time we care about it). Resolves: https://bugzilla.redhat.com/1529338 (It should also be applied to any maintenance branch that applies commit `7e62c4cd26` and friends to resolve https://bugzilla.redhat.com/1343919) Signed-off-by: Laine Stump <laine@laine.org>		2018-02-19 13:15:00 -05:00

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:

Contact

The libvirt project has two primary mailing lists:

libvirt-users@redhat.com (for user discussions)
