Re: Xenstore filling information about Dom0

["Waseem, Amna" <a.waseem@campus.tu-berlin.de>]

Thanks a lot.

I assume I will use manual_node to add nodes before starting xenstore daemon completely.

If I understand, manual_node just adds nodes and children. It doesnot add values.

Is there any way to add value of nodes as well?

Thanks
Amna

see tools/helpers/xen-init-dom0.c

see tools/libxl/ (various source files)

I guess you want to create xenstore nodes for all guests? You could use
a Xenstore watch for "@introduceDomain" to be called whenever a new
guest is added to Xenstore.

How should that work? Without xenstored daemon there is no Xenstore.
You can, however, create nodes at xenstored startup. See function
setup_structure() in tools/xenstore/xenstored_core.c
