Could you be a little more specific about that. I am pretty interested in getting this working. As far as I understand Xen is now running on 2.6.16-rc4 which does have kexec. I'm happy to put some cycles into updating the patch, though I must confess I am quite interested in Gerd's approach which is closer to what I was originally thinking. > The patch wouldn't allow kexec for dom0 anyhow.

I was only talking of DomU with regards to the assisted kexec patch that you sent earlier. I am also intersted in getting kexec working in Dom0, however I agree with Gerd's statements elsewhere in this thread that it can be acchived by porting kexec to Xen (or as I understand it given the current state of kexec, teaching kexec a few things about Xen in the prevailing architecture). I'm actually quite interested in getting both kexec and kdump working on both DomU and Dom0. I understand that for the most port there are really four different problems there. I'd really like to help out with existing efforts to help get all or any of them working. For now I'm going to poke around with Gerd's idea of asking xend to do system dumps for crash analysis of DomU, as that seems to be an area of little activity at this time. -- Horms _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
