NetBSD domU on ubuntu 16.04 / Xen 4.6.5

[Jukka Marin <jukka.marin%embedtronics.fi@localhost>]

Dear List,

I "accidentally" upgraded my dom0 to Xen 4.6.5 and my NetBSD domU's
(NetBSD 6.0) no longer started up.  All other domU's were still
working as expected.  I also tried a 7.1 XEN-DOMU kernel, with the
same results.

If I created the NetBSD guest as paused, it showed up in xl list,
but when I unpaused it, it immediately crashed (it seemed).

The NetBSD guests are my routers and I had to downgrade Xen to
4.6.0 to get my network up - so debugging this is not too simple.

Does anyone have any ideas - is NetBSD supposed to work under
Xen 4.6.5?

My domU config files are like this:

kernel = "/gw/images/netbsd-XEN3_DOMU-altq.gz"
memory = 512
name = "gw1"
vif = [ 'mac=00:0d:10:80:03:11, bridge=xenbr1', 'mac=00:0d:10:80:03:12, bridge=xenbr3', 'mac=00:0d:10:80:03:13, bridge=xenbr5' ]
disk = [ 'file:/gw/images/gw1.img,xvda,w' ]

Please Cc: to me.. thanks!
