The following dump-core patches changes its format into ELF, adds PFN-GMFN table, HVM support, and adds experimental IA64 support. - ELF format Program header and note section are adopted. - HVM domain support To know the memory area to dump, XENMEM_set_memory_map is added. XENMEM_memory_map hypercall is for current domain, so new one is created. and hvm domain builder tell xen its

We found machines with >32 E820 memory map entries, where Xen fails to boot (but Linux does boot fine). The native Linux (both x86 and x86_86) already has: #define E820MAX 128 /* number of entries in E820MAP */ Signed-off-by: Jun Nakajima <jun.nakajima@intel.com> Jun --- Intel Open Source Technology Center -- diff -r 3bb1857981e6 -r 51e9c0c806b2 xen/include/asm-x86/e820.h ---

I just built 4.3.0 in order to get > 2GB of RAM in domU with GPU passthrough without crashes. Unfortunately, the same crashes still happen. Massive frame buffer corruption on domU before it locks up solid. It seems the PCI memory stomp is still happening. I am using qemu-dm, as I did on Xen 4.2.x. So whatever fix for this went into 4.3.0 didn''t fix it for me. Passing less than 2GB

The following patches introduce the core infrastructure needed to paravirtualize the 32-bit x86 Linux kernel. This is done by moving virtualization sensitive insn's or code paths to a function table, paravirt_ops. This structure can be populated with hypervisor specific calls or native stubs and currently support running on bare metal, VMI, Xen, or Lhype. These patches apply to

This patch series is a reworking of a series developed by Mukesh Rathor at Oracle. The entirety of the design and development was done by him; I have only reworked, reorganized, and simplified things in a way that I think makes more sense. The vast majority of the credit for this effort therefore goes to him. This version is labelled v13 because it is based on his most recent series, v11.

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, V6: The only change from V5 is in patch #6: - changed comment to reflect autoxlate - removed a redundant ASSERT - reworked logic a bit so that get_page_from_gfn() is called with NULL for p2m type as before. arm has ASSERT wanting it to be NULL. Tim: patch 4 needs your approval. Daniel: patch 5 needs your approval. These patches implement PVH dom0. Patches 1 and 2

Hi all, These are the patches I'm planning to submit for 2.6.24. Comments gratefully accepted. Along with the usual cleanups and improvements are Jes' de-i386-ification patches, and a new "virtio" mechanism designed to be shared with KVM (and hopefully other hypervisors). Cheers, Rusty.
