Re: [Xen-users] patch to fix xendomains non-fatal error (4.5-unstable)

[Mark Pryor <tlviewer@xxxxxxxxx>]

Its solved, sort of. Your patch works if I do this:
http://pastebin.com/f8b0qW9X

So I fake a json config in /var/lib/xen for dom0, set it to
chmod 600 userdata-d.0*.libxl-json

reboot and all the warnings go away and 

systemctl status xendomains

sudo systemctl status xendomains

BTW, leaving out the contents of
%LIBEXEC/xen-init-dom0

doesn't help. AKAIK, it was never defined. What will it look like?

Did the roundtrip, with patching, compiling, building, reinstalling and testing
results are here

the libxl messages are still there about no dom0 config.
At least I learned how to modify ./tools/configure, but the problem remains.

its building now
