similar to: PCI device export

Hello, I''m trying to get working infiniband device in Xen. I have Xen v3 with 2.6.18 kernel. I export PCI device from Dom0 into DomU. I''ve enabled permisive device in Dom0. However, inserting infiniband module results in the following messages (with little more verbosity which I have added): pcifront pci-0: Installing PCI frontend pcifront pci-0: Creating PCI Frontend Bus

Hello, is there any reason why even permissive devices cannot write some areas in the PCI config space? The PCI_COMMAND is handled in special way so that the device is enabled/disabled properly, am I right? Why is PCI_INTERRUPT_LINE read from dev->irq and not from the config space? Why the PCI address bars are handled in very different way? And it seems that writing these bars is never

This issue was brought up about a year and a half ago. So I''ll bring it up again and see if anything happens. I''ve got an infiniband network and am attempting to pass the infiniband card through the host and give it to the guest. I''m working with standard CentOS 5.2 on both guest and host with their provided xen (3.0.3 ish). I''ve also attempted to install the

Hi, I found a link: http://xenbits.xensource.com/ext/xen-smartio.hg for Xen-IB source codes, but it did''t exist anymore. Are there other ways to get the Xen-IB source codes? Thanks.

When attempting to boot a system using Infiniband interfaces, ipconfig does not recognize Infiniband NICs as having valid MAC addresses, so they are silently ignored. As I would like to be able to netboot using Infiniband, I have patched ipconfig to support Infiniband interfaces. Fortunately, it's a pretty simple and straightforward patch. Below is the patch for your consideration. ---

I am running XCP 0.5. I have an InfiniBand network in place that I would like to use to connect to my NFS server for VM image storage. Has anybody tried getting IB to work with XCP? Is there a document that outlines the steps for getting IB to work with XCP? Also, I don''t need to expose the IB network to any of the domU. I only want to use the IB network to connecting to NFS based

Hello folks, I am running Xen 2.6 under Centos 5.2 installation, and am trying to port Xen migration abilities to Infiniband. But, the InfiniBand drivers do not work under Xen kernel, only under non-Xen kernels. It looks like I need to install some patches to rectify the situation. Has anyone ever worked with Infiniband and Xen and would be able to give me inputs about the same? I would really

Hi, all, Is the Xen currently compatible with the InfiniBand? I found some information about the Smart I/O module, but it was posted in 2006. Is the module still maintained? Or, are there any up-to-date alternatives for that?

Hi all, I''m getting my feet wet in the infiniband lake and of course I run into some problems. It would seem I got the compilation part of sles11 kernel 2.6.27 + Lustre 1.8.3 + ofed 1.4.2 right, because it allows me to see and use the infiniband fabric, and because ko2iblnd loads without any complaints. In /etc/modprobe.d/lustre (this is a Debian system, hence this subdir of

Hi, All, I used Infiniband to connect all GlusterFS nodes and the clients. Previously I run IP over IB and everything was OK. Now I used rdma transport mode instead. And then I ran the traffic. After I while, the glusterfs process exited because of segmentation fault. Here were the messages when I saw segmentation fault: pending frames: frame : type(0) op(0) frame : type(0) op(0)

Hey guys, I am running gluster over infiniband, and I have a couple of questions. We have four servers, each with 1 disk that I am trying to access over infiniband using gluster. The servers look like they start okay, here are the last 10 or so lines of a client log (they are all identical): 2008-10-07 07:18:40 D [spec.y:196:section_sub] parser: child:stripe0->remote1 2008-10-07 07:18:40 D

Dear List, We have lots of issues running Glusterfs over Infiniband. The client can mount the share, but when trying to access it by ls, df, touch du or any other kind the client hosts freeze the accessing shell and reboot is hardly possible. OS: CentOS 6.0 64 bit on i7 2600k machines Version: GlusterFS 3.2.2, also found in lower 3.2.1 Kernel Version 2.6.32 IB Stack and kernel

Greetings Xen user community, I am interested in using Mellanox ConnectX cards with SR-IOV capabilities to passthrough pci-e Virtual Functions (VFs) to Xen guests. The hope is to allow for the use of InfiniBand directly within virtual machines and thereby enable a plethora of high performance computing applications that already leverage InfiniBand interconnects. However, I have run into some

Hi! I would need an advice from those that use IB (as admins :) ) i have a choice between : 1. Mellanox InfiniHost? III Lx HCA card, single-port CX4, DDR, PCIe x8, mem-free, tall bracket, RoHS R5 2. QLogic Single Port 20 Gb InfiniBand to x16 PCI Express Adapter (Single Pack) aside the price is there anything else that could help me make a discrimination between this two? (these will be used in

Hi- I'm new to Gluster, but am trying to get it set up on a new compute cluster we're building. We picked Gluster for one of our cluster file systems (we're also using Lustre for fast scratch space), but the Gluster performance has been so bad that I think maybe we have a configuration problem -- perhaps we're missing a tuning parameter that would help, but I can't find

This morning I''ve had both my infiniband and tcp lustre clients hiccup. They are evicted from the server presumably as a result of their high load and consequent timeouts. My question is- why don''t the clients re-connect. The infiniband and tcp clients both give the following message when I type "df" - Cannot send after transport endpoint shutdown (-108). I''ve

Is anyone using Gluster with the Rocks cluster system? If so, do you know if there is a Roll for Gluster? Or, do you have any advice about things to do and things to avoid doing? We're considering using Gluster with Infiniband on our cluster and trying to learn whether other people have done this so we can perhaps learn from their experience. Thanks. ..

In IRC today, someone who was hitting that same IB performance ceiling that occasionally gets reported had this to say [11:50] <nissim> first, I ran fedora which is not supported by Mellanox OFED distro [11:50] <nissim> so I moved to CentOS 6.3 [11:51] <nissim> next I removed all distibution related infiniband rpms and build the latest OFED package [11:52] <nissim>

This looks like there could be some some problem requesting / leaking / whatever memory but without looking at the core its tought to tell for sure. Note: /usr/lib64/libglusterfs.so.0(_gf_msg_backtrace_nomem+0x78)[0x7f95bc54e618] Can you open up a bugzilla and get us the core file to review? -b ----- Original Message ----- > From: "???" <21291285 at qq.com> > To:
