Hi Don, Hi all, The key reason why I think that kexec/kdump does makes sense for xen, at least to some extent, is for the case where the hypervisor goes into a bad state, and you actually want to get rid of it and kdump into something else for forensics. There is also the advantage that by kexecing xen, you get access to the entire physical machine, either for crash-dump analysis, or because *gasp* you want to get out of xen for some other crazy reason :) And, on hardware that takes forever and a day to reboot, I believe that doing a kexec will be quite useful for hypervisor development. I would also like to note, that while my patch does involve moving parts of kexec/kdump into the hypervisor, and more similar parts need to be added in order to support other architectures, it is by no means all of kexec/kdump. -- Horms _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
