Hi Lamia, Currently there is no direct InfiniBand access support in the Official Xen trees. You might want to have a look at our Xen-IB implementation. A preliminary version can be downloaded here: http://xenbits.xensource.com/ext/xen-smartio.hg Some information about its design and applications can be found here: High Performance VMM-Bypass I/O in Virtual Machines (Usenix 06), and A Case for

Hi, I''m currently working on the latest version of xen with debian (lenny), and I have done 2 PCI passthrough, the fisrt one is with eth1 and i got no probleme with this one, but the second one is with a infiniband adapter=> It''s not working I got this message with dmesg on my DomU : [ 4.111023] ib_mthca: Mellanox InfiniBand HCA driver v1.0 (April 4, 2008) [ 4.111047]

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.

kmap_types.h is a misnomer because the old atomic MAP based array does not exist anymore and the whole indirection of architectures including kmap_types.h is inconinstent and does not allow to provide guard page debugging for this misfeature. Add a common header file which defines the mapping stack size for all architectures. Will be used when converting architectures over to a generic

The header is not longer used and on alpha, ia64, openrisc, parisc and um it was completely unused anyway as these architectures have no highmem support.

I've written a patch to add option-key submenus to menu.c32 and vesamenu.c32 for doing things like changing the video mode. This was inspired the the patch that SuSE applies to the syslinux family and Grub, without the ugly pseudo-PostScript spaghetti. The patch may be found at http://www.valleyhold.org/~gordons/syslinux-optmenus.diff (it's over 30K, so posting it here didn't seem

hi, i386 vcpu hotplug seems to work reliably but x86_64 does not and i think i have discovered why. in x86-64, a cpu within a domu can be removed with vcpu-set but subsequent calls do nothing. after xenwatch_thread grabs the event triggered by the write to the store, it calls the registered handler and never comes back. eventually, __cpu_die in drivers/xen/core/smpboot.c spins while waiting

Hello, I going to try to install OFED 1.4 on Xen 3.3 and I`d like to realize a VMM kernel bypass. Thanks to it my doomU will be able to communicate directly with my HCA and not pass by the dom 0. How can I realize that ? Is there a soft or something like that to do the kernel by pass ? I saw that it exist things like XEN-IB driver and SoftIB, there can i get it ? Or is VMM kernel bypass

Dear All, we are facing problem while connecting o2ib module. Lustre 2.2 with centos 6.3 gives problem while loading o2ib module for infiniband.

Dear All, I have been looking for resources on how to get Xen to work with infiniband. I do not have much experience with infiniband, or how to get it working on kernel, and how to configure xen to work with it. I would appreciate it very much if somebody can point me to some url or manuals to get the job done. Thank you, Lamia _______________________________________________ Xen-users

Hi Jan, I asked almost the exact same question as you about 6 months ago and someone provided some Gen4 results for me (But I can''t seem to find them in email), they were a fair bit better than Gen3. With IPOIB, you want connected mode and a large 32Kb+ MTU for max bandwidth, 1Gbyte/sec or more should be possible with Gen 4. Here are some of my original test results on my Opteron

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

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. ---

Dear Xen users, I'm trying to set up Xen in an HPC environment with IB to run MPI application via MVAPICH inside virtual machines. Has anybody managed to setup Infiniband connection from domU? Could you please share the details of how to achieve this? Thank you. Best Wishes. JinZhong.Tao _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

... Initializing.. hi all, I've a a very basic setup, directly two boxes via two MHEH28-XTC and I cannot activate them. One peculiar thing is I get (randomly & !often): [85947.090496] AMD-Vi: Event logged [ [85947.090539] IO_PAGE_FAULT device=09:00.7 domain=0x0000 address=0x00000000f6ffb000 flags=0x0050] [85947.298509] AMD-Vi: Event logged [ [85947.298550] IO_PAGE_FAULT device=09:00.7

Hello guys, I was wondering if someone could share their glusterfs volume and system settings if you are running glusterfs with infiniband networking. In particular I am interested in using the glusterfs + infiniband + kvm for virtualisation. However, any other implementation would also be useful for me. I've tried various versions of glusterfs (versions 3.2, 3.3 and 3.4beta) over the past
