The following series improves kexec in a Xen PVonHVM guest. It is available via git: git://github.com/olafhering/linux.git xen-kexec-XS_RESET_WATCHES-3.0 A new xenstored command XS_RESET_WATCHES has been added in xen-unstable.hg changeset 23839:42a45baf037d. The command removes all watches and transactions for the guest. The following patches make use of the new command to wipe all existing

This patch series implements the Linux Xen guest in terms of the paravirt-ops interface. The features in implemented this patch series are: * domU only * UP only (most code is SMP-safe, but there's no way to create a new vcpu) * writable pagetables, with late pinning/early unpinning (no shadow pagetable support) * supports both PAE and non-PAE modes * xen console * virtual block

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 Andi, This series of patches implements the Xen paravirt-ops interface. It applies to 2.6.21-rc7 + your patches + the last batch of pv_ops patches I posted. This patch generally restricts itself to Xen-specific parts of the tree, though it does make a few small changes elsewhere. These patches include: - some helper routines for allocating address space and walking pagetables - Xen
