[Pkg-xen-devel] Bug#805508: xen: Unable to create HVM domUs

[Thomas Jepp]

Source: xen
Version: 4.6.0-1
Severity: important

Dear Maintainer,

I attempted to create a HVM domU - using a config that previously worked 
on xen 4.4 (on Jessie).

When I execute "xl create <vm config>", I get:

Parsing config from router.internal.tomjepp.uk

An example config that triggers this issue:
