[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Dan Walsh <dwalsh@xxxxxxxxxx>

Add similar support to virt-sandbox-service that is in virt-sandbox
to add guest-bind, host-bind and host-image mount points on the command
line.  Openshift needs feature.

+If B<TYPE> is B<host-bind>, then B<SRC> is interpreted as the path to a directory on the host filesystem.

The "--include" option is useful for populating these temporary directories with copies of host files.
