The xm/xend toolstack has long been removed from Xen and replaced
|
||
|
|
with xl/libxl. The legacy xmdomain.cfg(5) configuration format is
|
||
|
|
still supported for backward compatibility, but xl.cfg(5) format
|
||
|
|
is preferred. Update the script documenation to reflect this.
|
||
|
|
|
||
|
|
When the legacy format is used, libxl places the entire target
|
||
|
|
string in $XENBUS_PATH/params, e.g. 'drbd:myresource'. To ensure
|
||
|
|
the script continues to work with the legacy configuration format,
|
||
|
|
strip any 'drbd:' prefix from the resource identifier read from
|
||
|
|
xenstore.
