New subject: [libvirt] [PATCH v2 1/4] libvirt_private.syms: Expose virDomainNetTypeFromString
The enum converters are defined in the domain_conf.h (so
accessible widely across the code), but on the symbol layer, only
virDomainNetTypeToString was exposed. However, FromString variant
is going to be needed shortly.

New subject: [libvirt] [PATCH v2 2/4] virsh attach-interface: Use enum instead of arbitrary integers
The type of interface to attach is held in the variable 'typ'.
Depending on interface type selected by user, the variable is set
either to 1 (network), or 2 (bridge). Lets use already existing
enum from domain_conf.h instead: virDomainNetType.

New subject: [libvirt] [PATCH v2 4/4] virsh attach-interface: Allow macvtap hotplug
Our hotplug code supports macvtap insertion to guests. However, we
somehow forgot about 'attach-interface' (which tries to build XML from
passed arguments and use virDomainAttachDeviceFlags()).
New type is accessible under 'direct' type, to keep the same type as
used in domain XML.

If you want to merge 1-3 into just one patch that'd be fine too... At
the very least 1&3 are related since the From API isn't used until 3.

I had thought that during V1 of this patch series there had been enough
sentiment about not pulling in private parts of libvirt internals that
this V2 (posted 2 minutes before the last comment in V1, so very
literally crossing in the inter-tubes) would be discarded in favor of
something that only used public APIs - the last word on the subject was
this:
https://www.redhat.com/archives/libvir-list/2015-February/msg00284.html
(Yes, I know there are other places where it's already done, but it
seems like a better idea to clean those up than to compound the pollution.)

Yeah, I'd prefer that in general, but this particular patch is only using
the trivial VIR_ENUM string/int conversion, so I'm willing to overlook it
for this. If the internal API being used were non-trivial then I'd say
we should look at the public API support.

Daniel
