Hi Thanks for the detailed info given in the wiki http://sourceforge.net/apps/mediawiki/embeddedxen/index.php?title=GettingStarted . I am running in to a panic issue (panic at hypervisor.c) when trying to get the system up and running (as given in the wiki), which prevents xen from booting. This is what I have done. 1. I have a virtual machine having ubuntu-9.10 where I followed and installed the packages as given in the wiki. 2. In addition to that, I did install the following packages, brctl, uml-utilities (for 'tunctl') and uboot-mkimage as they were not there in my ubuntu-9.10 VM. 3. Also I changed the /etc/wemu-ifup script as follows (added two more lines to what is givien in the wiki for adding the bridge being linking it with the tap0 interface.) /etc/qemu-ifup #!/bin/sh BRIDGE=br0 #setup in promiscuous mode qemu's device echo ifconfig $1 0.0.0.0 promisc up ifconfig $1 0.0.0.0 promisc up echo brctl addbr $BRIDGE brctl addbr $BRIDGE #add it to the bridge echo brctl addif $BRIDGE $1 brctl addif $BRIDGE $1 4. After that I created two dummy flash files 'flash1' and 'flash2' of sixe 32 MB as follows $> sudo dd if=/dev/zero of=./flash2 bs=32000000 count=1 5. Then I ran 'qemu' and got the panic at 'hypervisor.c' which I am giving below. It would be great if you could let me know how to fix it and get it running. ------------------------------------------------------------------------------------------------------------------------------------------ user@ubuntu:~/embeddedxen# sudo qemu-system-arm -localtime -M mainstone -kernel ./xen/arch/arm/boot/uImage.mainstone -s -m 256 -pflash ./flash1 -pflash ./flash2 -net nic -net tap,ifname=tap0,script=/etc/qemu-ifup ifconfig tap0 0.0.0.0 promisc up brctl addbr br0 device br0 already exists; can't create bridge with the same name brctl addif br0 tap0 map addr 0x82200a0 root@ubuntu:~/embeddedxen# sudo qemu-system-arm -localtime -M mainstone -kernel ./xen/arch/arm/boot/uImage.mainstone -s -m 256 -pflash ./flash1 -pflash ./flash2 -net nic -net tap,ifname=tap0,script=/etc/qemu-ifup -serial stdio ifconfig tap0 0.0.0.0 promisc up brctl addbr br0 device br0 already exists; can't create bridge with the same name brctl addif br0 tap0 map addr 0x82200a0 Uncompressing Xen................................... done, booting the kernel. __ __ _____ _ _____ _ _ _ _ \ \/ /___ _ __ |___ / / | |___ / ___ ___ | (_) |__ _ __(_) \ // _ \ '_ \ |_ \ | | |_ \ __ / __/ _ \| | | '_ \| '__| | / \ __/ | | | ___) || |_ ___) |__| (_| (_) | | | |_) | | | | /_/\_\___|_| |_| |____(_)_(_)____/ \___\___/|_|_|_.__/|_| |_| http://www.cl.cam.ac.uk/netos/xen University of Cambridge Computer Laboratory Xen version 3.1.3-colibri (root@) (gcc version 4.1.2) Wed Feb 11 11:24:14 CET 2009 EmbeddedXEN/PENAR Project - Reconfigurable Embedded Digital System (REDS) Institute from HEIG-VD/Switzerland http://reds.heig-vd.ch Latest ChangeSet: unavailable (XEN) Hypervisor area start at: 0xff000000 (virt) (XEN) Physical RAM map: (XEN) 00000000a0000000: 0000000004000000 (XEN) End of multi-kernel area (XEN+dom0/U) -> min_page: 0xa0100 (XEN) End of Xen Area: 2561MiB (2622464KiB) (XEN) End of RAM: 0xa3f00000 (XEN) Boot allocator @ a0100000 - a0115000 (XEN) NUMA turned off (XEN) Faking a node at 0000000000000000-00000000a3f00000 (XEN) xenheap: 00000000a0115000 - 00000000a0314fff (XEN) xenheap(virt): ff115000 - ff314fff (XEN) ### frametable: ff315000 (XEN) ### min_page: a0100 (XEN) ### ps = a0115000 maddr_to_virt(ps)=ff115000 maddr_to_page(ps)=ff3151f8 (XEN) Xen heap: 2MiB (2048kiB) (XEN) ### first_valid_mfn = a0315 (XEN) ### max_page = a3f00 (XEN) Domain heap initialised: DMA width 32 bits (XEN) Dom Heap: 15230 pages (XEN) CPU: XScale-PXA270 [69054117] revision 7 (ARMv5TE) (XEN) (GCD) xen/arch/arm/hypervisor/mm.c:2070:vector_pt_init(): alloc_xenheap_page (XEN) Mapping I/O on mainstone...
