You'll need a function in tools/libxc/ that'll do the dump (I guess this is what you have already). Then you'll need to add a Python wrapper for this function in tools/python/xen/lowlevel/xc/xc.c. This shouldn't be too hard, using the other functions in there as a template... Finally you'll need to provide a means to dump using the xm tool. This touches quite a few files, I'm afraid, although none of them require complex changes... It looks like you'll need to edit: * tools/python/xen/xm/main.py to add a subprogram for doing a dump. * tools/python/xen/xend/XendClient.py to add a method for requesting a dump from the server * tools/python/xen/xend/server/SrvDomain.py to add an operation for dumping a domain (this will get activated when the client makes a request) * tools/python/xen/xend/XendDomain.py to add a domain_dump() method to be called by SrvDomain.py (this will pause the domain, call your Xc dump function and unpause it) You may find it helpful to compare the call paths triggered by a destroy or a save, which will be similar to what you want. For icing on the cake, you could also rig up some kind of dumping in the reap() function in XendDomain.py to autodump crashed domains before restarting / destroying them.
