[libvirt] [PATCH RFC 0/2] conf: add net device prefix capability

[Joao Martins]

Hey,

Back in the pre 1.3.0 release [0] we had a regression when migrating
domains in libxl (introduced by the reverted commit d2e5538b1).
The chosen solution to address this problem was to introduce a
capability to be used by the virDomainNetDefFormat() and
virDomainNetDefParseXML() routines. This series implements this,
and I would ask if it's in line with what you had in mind by
exposing as a hypervisor capability?

For the purposes of RFC and compability with other drivers I left
the hardcoded checking of VIR_NET_GENERATED_PREFIX plus checking a
prefix registered by the driver.

Having this series and the reverted commit applied, I can
successfully migrate a domain without seeing the same interface
name on both source and destination node.

Thoughts?

Thanks!
Joao
