...SDL fastboot list. There are a number of Xen folks who''ll want to look at the code. For the fastboot folks, this is mostly intended as an announcement of the port. Please limit your replies to the list(s) that they applies to, thanks :-) A number of people have expressed interest in kexec support for Xen guests. In particular, it''s mainly useful for purposes of implementing an in-guest bootloader app and avoiding the need for dom0 to access the guest filesystem. It''s a largish patch, so I stuck it online: http://www.cl.cam.ac.uk/~maw48/xenguest_kexec.patch Tes...

While trying to port kexec cleanly to klibc, came across this syscall usage for reboot(2). Calling reboot directly simplifies the code.

Add guide to using the kexec and kdump facility in xen. Signed-off-by: Simon Horman <horms@verge.net.au> --- I the work on this document using an ia64 machine and qemu emulating x86_32. I am yet to verify it on x86_32 hardware or x86_64. Index: xen-unstable.hg/docs/misc/kexec_and_kdump.txt ============================...

Is it possible to kexec to the syslinux interface, thus bypassing the hw initialization? What would be the kexec command? kexec -l ??? --append=??? --initrd=??? TIA Jorge Almeida

Hi, This set of patches contains initial kexec/kdump implementation for Xen v2 (previous version were posted to few people by mistake; sorry for that). Currently only dom0 is supported, however, almost all infrustructure required for domU support is ready. Jan Beulich suggested to merge Xen x86 assembler code with baremetal x86 code. This coul...

Hi all, Here I am sending as attachments patches enabling kexec/kdump support in Xen PV domU. Only x84_64 architecture is supported. There is no support for i386 but some code could be easily reused. Here is a description of patches: - kexec-tools-2.0.3_20120522.patch: patch for kexec-tools which cleanly applies to version 2.0.3, - kexec-kernel-only_201...

Hi all, I was messing around with kexec and it seems to work just fine on KVM, but for Xen domU images, it doesn't work at all. Daniel, I saw some patches from you back in September 2012 for adding this support for Dom0, but they don't seem to have gone into the kernel (but other patches went into kexec-tools at that time.) You...
