The memory relating guest domain should be allocated from NUMA node on which the guest runs. Because the latency of the same NUMA node is faster than that of a different one. This patch fixes memory allocation for Address Translation Structure of VT-d. VT-d uses two types of Structures for DMA address translation. The one is Device Assignment Structure. The other is Address Translation

...default Rails behavior should be to NOT log the POST parameters when in production mode. Is this something that needs to be addressed? If so, what''s the correct way to escalate it? At the very least, I think there should be clear warnings and documentation about this fact.

Hi, Keir, These patches are rebased version of Yunhong''s original patches, which were sent out before XEN 3.2 was released. These patches enable MSI support and limited MSI-X support in XEN. Here is the original description of the patches from Yunhong''s mail. The basic idea including: 1) Keep vector global resource owned by xen, while split pirq into per-domain

Fixes made in version 2: 1) Use PML4[257] for ioremap of PCI mmcfg. As full 16-bit segment support would require 44-bits. Since each slot only has 39-bits, we support 2048 PCI segments for now. This can be easily expanded if deemed necessary in the future. 2) Integrated PCI mmcfg access with existing PCI config interface for x86_64. Use MMCFG interface if offset is greater than 256.

Hi, I''ve added some preliminary support for VT-d for paravirtualized guests. This must be enabled using an ''iommu_pv'' boot parameter (disabled by default). I''ve added some python bindigs to allow xend to assign PCI devices to IOMMU for PV guests. For HVM guests this is handled in ioemu. Not sure if it makes sense to handle both cases in one place. The

Hi, Keir, This patch will move reading and writing of PCI configuration spaces from dom0 to Xen. It also changes VTD code, so that they can touch the PCI configuration spaces with proper lock. This will also benefit MSI support in Xen. Can you give some comments? Thanks! <<pci_conf_xen.patch>> Best Regards Haitao Shan _______________________________________________ Xen-devel

...e_method()" It seems to me you could also have cron execute a wget to a page like: wget http://www.domain.com/controller/action/id And I vaguely remember someone saying they were working on a better solution (as a plugin?). What are people actually using? What works best? Thanks, Kevin Skoglund

Hi, I''m struggling with this and I''m not sure if it is obvious or dumb (or both). I have a basic create method like so: def creatematerial @material = Material.new(params[:material]) if @material.save flash[:notice] = "Material successfully created." end Ok so far, but now I want to retrieve that object that was just saved so that it can be used in the

i''ve got several methods in my models i use to find based on certain criteria...i''ve done this so the controller code is less cluttered, plus the DRY factor. example: class Foo < ActiveRecord::Base def find_by_something(something) find :all, :joins => ..., :conditions => ... end def find_by_something_else(something_else) find :all, :joins => ...,

Hi everyone, I''m at the end of my rope on this. I can''t get pagination to work with anything but a standard find on a model. If I try to do a search and customize the pagination, I get lots of different variations. My thought was to have the list action do what it does, but to pass it a list of search conditions from the search action. So, if search determines that we need

On Xen-3.3.0, domain0 Megaraid SAS (SAS 1068 controller) driver is not loading correctly if vtd support in Xen is enabled. It fails at the point of initializing firmware. I wasn''t seeing this error with Xen-3.2.2-rc3 (Unstable version), though with vtd disabled in Xen-3.3.0, it is working. Looks like a degrade problem. Any clues? Thx, Venkat

How do i pass the link text as a parameter to a controller i want to pass the string rather than the id??? Is there any way how can I do that? -- Posted via http://www.ruby-forum.com/.

When I started Rails Development, I needed to use ''killall -g dispatch.fcgi'' whenever I made a change to a Model to see the change on my website. Now it seems I need to do this to see any change to the Controller as well. Any ideas of what I am doing wrong??? -- Posted via http://www.ruby-forum.com/.

.... The disadvantage of sessions is that they take up space on your server. You''ll want to decide how to manage them depending on the needs of your application--periodically deleting old sessions (using cron) or storing sessions in a database are two frequent techniques.

Is there a way to update attributes in a HABTM join table? Right now I am deleting the join and then recreating it with new attributes. I have a table "categories" and another table "items". They are both HABTM with the join table "categories_items" between them. If an item is joined to a category once, no problem, we create the join. But if an item is
