A dedicated Xen driver domain init service starts "xl devd" in domU. But currently, it is only supplied in the form of a SysV init script, which systemd users run through a backward compatiblity wrapper automatically generated by systemd-sysv-generator. This patch adds a (naturally more lightweight) native systemd unit to be used instead. The xendriverdomain service is only relevant to domU, but should not run in dom0. Therefore, the systemd unit uses "ConditionVirtualization=xen", which evaluates to true in domU and (since systemd version 214, released on 2014-06-11) to false in dom0. Users or distributors who need to be compatible with even older systemd versions, but still want to prevent "xl devd" startup in dom0, could add the following line in [Service]: ExecStartPre=/bin/sh -c "! grep -q control_d /proc/xen/capabilities" (Please rerun autogen.sh after applying this patch) Signed-off-by: Rusty Bird <rustybird@openmailbox.org> Cc: Ian Jackson <ian.jackson@eu.citrix.com> Cc: Wei Liu <wei.liu2@citrix.com> Acked-by: Wei Liu <wei.liu2@citrix.com> [ wei: rerun autogen.sh ]
