Xen project Mailing List

Hello,

First Problem:

>Which systemd services files from xen are enabled? See the systemd part
>of the INSTALL file:
>http://xenbits.xen.org/gitweb/?p=xen.git;a=blob_plain;f=INSTALL;hb=staging

When compiled from source, no options where given, my ubuntu is installed with systemd, so I guess the part of the installation file that states:
"
...

NOTE: if systemd development packages are installed the systemd support
will be the enabled per default.
...

Is somehow related to my situation.

>systemctl enable xen-qemu-dom0-disk-backend.service
>systemctl enable xen-init-dom0.service
>systemctl enable xenconsoled.service

These MAGIC lines did the trick! Thanks for the help, this solved the First Problem, BUT, if you know those lines, can't you submit a patch to fix this issue for the next "Lucky user"? How can I help to fix it?

Second Problem:

Should I ask the user list of the systemd?

After fixing the first problem, with those lines stated above here is the new output:
"

Third Problem: Already SOLVED.

Fourth Problem:

After fixing the Third problem the Fourth Problem solved itself by MAGIC... Probably it was somehow related to the language being used by the system... Anyway... Thanks for the help.

Which systemd services files from xen are enabled? See the systemd part
of the INSTALL file:
http://xenbits.xen.org/gitweb/?p=xen.git;a=blob_plain;f=INSTALL;hb=staging

systemctl enable xen-qemu-dom0-disk-backend.service
systemctl enable xen-init-dom0.service
systemctl enable xenconsoled.service

This is a bug in systemd. It assumes that all modules listed in
/usr/lib/modules-load.d/ are available in each and every runtime kernel.
Even grandma knows that this is not true. Just ignore errors from that
service.
