Export initrd in debugfs when retained. As a side effect, initrd_start and initrd_end are not cleared when the initrd is retained. After this patch, one can then copy the initrd space from debugfs and pass it to kexec as the initrd, or do something else with it (maybe it was an initrd not an initramfs).

...g statements into the gunzip function to see what was happening. The core of the problem is in the init/initramfs.c, the populate_rootfs and unpack_to_rootfs functions. I see a 512byte image at &__initramfs_start being uncompressed. Then I see my image during the dry-run inside the "if (initrd_start)" block, which gets checked correctly with gunzip(). The problem is that the same call to unpack_to_rootfs() finds another header, which is broken. I solved the problem with the following patch. I realize this isn't a really good patch (it doesn't even wait to check the status of th...

As promised to Andrew, and with much thanks to Andi Kleen for feedback, this is the new series of lguest patches. Main change is the move to drivers/lguest (for future non-i386 expansion), but lots of cleanups driven by Andi's feedback and the documentation effort (which made me examine every line of code). It's not perfect, but it's definitely useful. Cheers, Rusty. List of

Unlike full virtualization in which the virtual machine provides the same platform interface as running natively on the hardware, paravirtualization requires modification to the guest operating system to work with the platform interface provided by the hypervisor. Xen was designed with performance in mind. Calls to the hypervisor are minimized, batched if necessary, and non-critical codepaths

Hi. This patchset implements ia64/pv_ops support which is the framework for virtualization support. Now all the comments so far have been addressed, but only a few exceptions. On x86 various ways to support virtualization were proposed, and eventually pv_ops won. So on ia64 the pv_ops strategy is appropriate too. Later I'll post the patchset which implements xen domU based on ia64/pv_ops.
