I've been looking back at the history of why this code was added in the
first place to make sure we're not inadvertently breaking something else.
It looks like originally that code did check that ipaddr hadn't changed
(when there was a single IP address), which wasn't needed but also
didn't hurt anything (since ipaddr would always be 0 for type='ethernet'
in the qemu driver. Then recently (commit aa2cc7) support for multiple
IP addresses with type='ethernet' was added (apparently for LXC, but
also added for openvz), any code that had touched ethernet.ipaddr was
changed to look at nips and the ip array instead, but the code that
replaced the unnecessary but innocuous check in qemu_hotplug.c was done
incorrectly. So the correct thing *is* to simply remove the check.
All of that is a long winded way of saying ACK. I'll push it in awhile.
Thanks!
I don't see this change in current master. Does it goes to 1.2.19 or to 1.2.20?
It was pushed on on Monday, commit id
bbc705d1309b8ec2eb4cdae011dc702802c96d11. It will be in 1.2.19. I took
the liberty of expanding the commit log message, so you may not have
recognized it:

Eliminate incorrect and unnecessary check for changed IP address
Commit aa2cc7 modified a previously unnecessary but innocuous check
for interface IP address during interface update incorrectly, causing
all attempted updates (e.g. changing link state) to interfaces of
type='ethernet' for QEMU to fail.
This patch fixes the issue by completely removing the check for IP
address, which is pointless since QEMU doesn't support setting
interface IP addresses from the domain interface XML anyway.
