Hi Simon, Thanks for your work on this. I tried to give it a whirl on an HP zx2000 system (UP, zx1, Madison). Probably user error, but I can't get kexec to accept the --append option when built as described in your instructions. It gives me this error: # kexec -l --append "dom0_mem=1G -- root=/dev/hda2" --vmm "/boot/xen.gz" "/boot/vmlinux.gz" Cannot open `dom0_mem=1G -- root=/dev/hda2': stream error So I went ahead and tried it w/o an append option... it nearly works! The log is below. Xen kexec'd, but dom0 panic'd. I wasn't able to boot my system with the phys_efi option, it hangs right after the vhpt_init line. I'll see if I can figure out what's going on there. Thanks, Alex PS - I'm using your patches based on current xen-ia64-unstable.hg tip, which changed a little bit since yesterday. That might have something to do w/ it. -- Alex Williamson HP Open Source & Linux Org. # kexec -l --vmm "/boot/xen.gz" "/boot/vmlinux.gz" # kexec -e ACPI: PCI interrupt for device 0000:a0:03.0 disabled GSI 42 (level, low) -> CPU 0 (0x0000) vector 50 unregistered Starting new kernel __ __ _____ ___ _ _ _ \ \/ /___ _ __ |___ / / _ \ _ _ _ __ ___| |_ __ _| |__ | | ___ \ // _ \ '_ \ |_ \| | | |__| | | | '_ \/ __| __/ _` | '_ \| |/ _ \ / \ __/ | | | ___) | |_| |__| |_| | | | \__ \ || (_| | |_) | | __/ /_/\_\___|_| |_| |____(_)___/ \__,_|_| |_|___/\__\__,_|_.__/|_|\___| http://www.cl.cam.ac.uk/netos/xen University of Cambridge Computer Laboratory Xen version 3.0-unstable (root@home) (gcc version 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)) Thu Feb 15 16:22:53 MST 2007 Latest ChangeSet: Thu Feb 15 16:21:52 2007 -0700 13977:37f404ca595b (XEN) Xen command line: (XEN) xen image pstart: 0x4000000, xenheap pend: 0x8000000 (XEN) Xen patching physical address access by offset: 0x0 (XEN) find_memory: efi_memmap_walk returns max_page=102fff2 (XEN) Before xen_heap_start: f0000000041b0880 (XEN) After xen_heap_start: f0000000043bc000 (XEN) warning: skipping physical page 0 (XEN) Init boot pages: 0x4000 -> 0x4000000.
