Xen and Kexec
Hi,
I understand that kexec can boot xen and a dom0 kernel with a
multiboot patch. Is it possible to reboot a dom0 kernel with kexec? I
suspect the answer is "no," since the dom0 kernel is actually running
under xen, but I do not understand the code well enough to answer. If
the answer is "yes," how can one get the kexec option to appear in the
kernel config file (for linux) of an arch=xen kernel.

Thanks,
Andy

No. kexec would need to be ported for XenLinux, and would reboot Xen
rathe rthan just DOM0.
