create ! title it xl lacks support for xm create -F (sxp config file syntax) On Mon, 2013-09-02 at 13:32 -0700, Matt Wilson wrote: > > Live migration between a system running xend to a system that doesn't > support xend would be a nice-to-have.

Matt mentioned elsewhere that they use "xm create -F" which takes a configuration file in the xend sxp format (I had no idea this option existed). I don't think we really want to be adding SXP code to xm but perhaps we can produce a conversion tool? Matt, can you provide some examples of the actual SXP you care about, we obviously don't want to be worrying about the bits which aren't actually used.

Indeed, also mentioned elsewhere it's probably not in the best interest of the project to go adding SXP support when we already have more well adopted options like json. > Matt, can you provide some examples of the actual SXP you care about, we > obviously don't want to be worrying about the bits which aren't actually > used. Honestly I think it'd be less total work to avoid SXP altogether. There are some other differences that need to be carefully considered, and shifting config file formats is a forcing function for looking closely for those differences. --msw _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel

I suppose I should close this bug. If anyone else has a requirement for this stuff now would be a good time to say so. I'll also add it to http://wiki.xen.org/wiki/XL#Anti-Features.
