Current virtio-net drivers that support the failover feature match up
the virtio backup device with its corresponding hostdev device by
looking for an interface with a matching MAC address. Since libvirt
will assign a different random MAC address to each interface that
isn't given an explicit MAC address, this means that the configuration
for any failover pairs must include explicit matching MAC addresses.
To make life easier, we could have libvirt populate the XML config
with the same auto-generated MAC address for both interfaces when it
detects a failover pair that have no MAC addresses provided (a
failover pair can be detected by matching <alias name='blah'/> of the
virtio interface with <driver backupAlias='blah'/> of the hostdev
interface), but then we would be stuck with that behavior even if the
virtio guest driver later eliminated the requirement that mac
addresses match.
Additionally, some management software uses the MAC address as the
primary index for its list of network devices, and can't properly deal
with two interfaces having the same MAC address (oVirt). Even
libvirt's own virsh utility uses MAC address (combined with interface
type) to uniquely identify interfaces for the virsh detach-interface
command (in this case, fortunately the runtime interface type is used,
so one of the interfaces will always be of type='hostdev' and the
other type='something-else", so it doesn't currently cause any problem).
In order to remove the necessity of explicitly setting interface MAC
addresses, as well as permit the two interfaces of a failover pair to
each have a unique index while still fulfilling the current guest
driver requirement that the MAC addresses matchin the guest, this
patch adds a new attribute "useBackupMAC" that is set on the hostdev
interface of the pair. When useBackupMAC='yes', the setup for the
hostdev interface will find the virtio failover interface (using
backupAlias) and use that interface's MAC address to initialize the
MAC address of the hostdev interface; the MAC address in the hostdev
interface config remains unchanged, it just isnt used for device
initialization.
I made this patch to followup on
https://bugzilla.redhat.com/show_bug.cgi?id=1693587#c12 (where I
suggested this attribute as a possible remedy to oVirt's requirement
that each network device have a unique MAC address).
Truthfully, I'm not convinced that I want it though, as it seems
"a bit" hackish. In particular, I've thought for a long time that the
"hostdev manager" code in util/virhostdev.c should really live in the
node device driver and be called from the hypervisors via a public API
(so that there is one central place on the host that maintains the
list of in-use PCI devices and their status), but this patch adds an
obstacle to that goal by adding a virDomainDefPtr to more of the APIs in
that library - if this was turned into a public API, then entire
virDomainDef would need to be serialized and sent in the API call,
then parsed at the other end - yuck :-/. NB: there are already
functions in virhostdev.h that take a virDomainDefPtr, so maybe I'm
being too sensitive.
On the upside, it solves a problem, and default bevahior is unchanged.
So although we would have to live with the presence of this option
forever once added, at least it would never be used unknowingly - the
behavior it triggers would only occur if it was explicitly called out
in the config.
