This is a new version of the unified lguest launcher that applies to the current tree. According to rusty's suggestion, I'm bothering less to be able to load 32 bit kernels on 64-bit machines: changing the launcher for such case would be the easy part! In the absence of further objections, I'll commit it. Signed-off-by: Glauber de Oliveira Costa <gcosta@redhat.com> -- =

The following dump-core patches changes its format into ELF, adds PFN-GMFN table, HVM support, and adds experimental IA64 support. - ELF format Program header and note section are adopted. - HVM domain support To know the memory area to dump, XENMEM_set_memory_map is added. XENMEM_memory_map hypercall is for current domain, so new one is created. and hvm domain builder tell xen its
