Xen devel - Mar 2010 - [XCP] XCP project suggestions on the wiki

Hi,

I''ve collected together a bunch of XCP-related project suggestions and
stuck them on the xen wiki:

http://wiki.xensource.com/xenwiki/XAPI_project_suggestions

The main idea is that new people who want to work on XCP can use this list for
inspiration... each idea has a rough guesstimate of size/ knowledge required/
impact and an initial first contact (who either suggested the idea originally or
who is willing to help someone work on it)

I think a good next step would be to expand the list
* to include projects related to the items on the XCP roadmap; and 
* to describe prototypes which are actively being worked on.

As always, comments and suggestions are welcome!

Cheers,
Dave

Great, this is a good idea!

I''ve been planning on adding support for better iSCSI multipathing to
XCP,
but haven''t had time yet..

I guess I could write that down to the list and describe it in more detail,
as a first step :)

Two more ideas:

- Storage Live Migration, allow moving the guest from storage A to storage B
on-the-fly without reboot (VMware Storage Vmotion)
- Live Migration without shared storage (I think Qemu already has support for
this)

What do you think of these?

Sounds good! There might be prototype code lying around somewhere. Daniel, do
you guys have something relevant?

Does qemu remote the block I/O itself? This would also be quite interesting.

Cheers,
Dave

it copies the storage to the destination along with the memory.

For Xen/XCP this would have to be done with other methods than Qemu obviously.

Both the Live Migration without shared storage, and the storage live migration
should work for both PV and HVM guests.

I added "Better iSCSI multipathing" to the wiki page.
