I actually ended up going from Debian-packaged 4.4.x to Mark Pryor's
Debian packages because I needed to upgrade version and patch some
XSAs during embargo. At the time there wasn't much going on with the
Debian packaging and I didn't feel confident to do it myself, so I
based things off of Mark's work.

I used that as a basis for 4.8.x and now 4.10.x packages. Now that
you are helping with Debian packaging I would like to come back to
Debian's packages, probably along with an upgrade to buster.

The systemd stuff from those packages of Mark's did solve this
problem though. I assume this is upstream content. I think in 4.4 it
was generating a systemd service from an init script, whereas now
it's a native systemd service. Here's /lib/systemd/system/xendomains.service:

[Unit]
Description=Xendomains - start and stop guests on boot and shutdown
Requires=proc-xen.mount xenstored.service
After=proc-xen.mount xenstored.service xenconsoled.service
xen-init-dom0.service
After=network-online.target
After=remote-fs.target
ConditionPathExists=/proc/xen/capabilities
Conflicts=libvirtd.service

[Service]
Type=oneshot
RemainAfterExit=true
ExecStartPre=/bin/grep -q control_d /proc/xen/capabilities
ExecStart=-/usr/lib/xen-4.10/bin/xendomains start
ExecStop=/usr/lib/xen-4.10/bin/xendomains stop
ExecReload=/usr/lib/xen-4.10/bin/xendomains restart

[Install]
WantedBy=multi-user.target

Those packages came from:

http://107.185.106.30/xen/debian/stretch-nmu/4ax/

(plus the XSAs published since then)

Would it be helpful if I installed buster and
xen-hypervisor-4.11-amd64 and checked how the systemd unit files
cope with trying to start 75 or so domains? If so I will try to find
some time to try that,

Cheers,
Andy
