[libvirt] [PATCH V2 1/6] driver config: Introduce virFirmware object
Jim Fehlig

Wed Jun 8 23:42:53 UTC 2016
FYI, there seems to be a problem withint-mx.corp.redhat.com. It failed to post
0/6 and 3/6 with
550 5.1.1 <libvir-list at redhat.com>... User unknown (in reply to RCPT TO command)
I'm rather reluctant to spam the list by resending the series.
Regards,
Jim
