[Pkg-xen-devel] Bug#862493: xen-utils-common: xendomains fails to restore saved domU

[Mike Edwards]

Package: xen-utils-common
Version: 4.8.1-1+deb9u1
Severity: important

I've noticed since upgrading to stretch that xendomains is failing to restore my
saved domUs from a previous shutdown.

Running the save/restore manually gives me more info:

# xl save 2 /var/lib/xen/save/dl

xendomains config from /etc/default/xendomains:
