Hi, I''ve been trying to use E5520 and X5650 together in an heterogeneous pool without success. I know the combination is not on the official XenServer supported list (http://hcl.xensource.com/CPUPoolsList.aspx), but I thought it would be possible to set the mask anyway and see for myself if the combination works… My problem is that the mask doesn''t "stick" after a

I was wondering why Ajax.Autocomleter didn''t support array-style parameters for the Ajax.Request and opened the following enhancement request: http://dev.rubyonrails.org/ticket/10612#preview Any comments?

TEST: ===== SAMBA STRESS OVER GIGABIT NETWORK: This is a simple Read/Write/Compare/Delete kind of test over the network via Samba. Multiple clients with multiple threads try to read/write/compare/delete(in a loop) a finite sized file (64K block size) over samba for a prolonged period of time in an effort to stress test the server.

Fairly straight code motion. Split non-virtualizable pieces of processor.h into default and VMI subarches. CPUID is non-virtualizable, since it doesn't trap, and very often the hypervisor will want to hide specific feature bits from the kernel. To provide a replacement for call sites that use CPUID as a serializing instruction, the sync_core() macro is still available. Signed-off-by: Zachary Amsden &lt...

Hi all, I've been looking at finding common ground between the VMI, Xen and other paravirtualization approaches, and after some discussion, we're getting somewhere. These first two patches are the fundamentals, stolen mainly from the VMI patches: removing assumptions about the kernel running in ring 0, and macro-izing all the obvious para-virtualize-needing insns. The third patch is

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

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
