[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH] add xl init scripts
Hi all,
this patch adds an init script for xl, so that it can be used without
xend installed on the system.
In cases in which both toolstacks are present, only one init script
will be run, dependening on the value of xen_toolstack in
/etc/sysconfig/xen_toolstack.
Please note that a correct value of xen_toolstack (either xl or xend),
is required now.
The network script and the vif script to be used with xl can be
specified in /etc/sysconfig/xenlightdaemons.
Xl sets the vif script to xl-vif-script by default, that reads
/etc/sysconfig/xenlightdaemons and calls the vif script set there.
A port to a debian system should be straightforward, just replacing
/etc/sysconfig with /etc/default everywhere.
