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 appreciate any kind of help in the matter. Thanks & Regards, Siddharth Wagh ---------------------------------------------------------------------------------------------------------------------------------------------------------- Many of life''s failures are people who did not realize how close they were to success when they gave up... ---------------------------------------------------------------------------------------------------------------------------------------------------------- _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Thanks Nathan. But, it gives the following error during yum installation: Transaction Check Error: package libibverbs-2.2-33596.832.1_1_1.rhel4_qlc (which is newer than libibverbs-1.1.1-9.el5) is already installed package libibverbs-devel-2.2-33596.832.1_1_1.rhel4_qlc (which is newer than libibverbs-devel-1.1.1-9.el5) is already installed Thanks & Regards, Siddharth Wagh ---------------------------------------------------------------------------------------------------------------------------------------------------------- Many of life''s failures are people who did not realize how close they were to success when they gave up... ---------------------------------------------------------------------------------------------------------------------------------------------------------- On Mon, Feb 23, 2009 at 1:11 PM, Nathan Stratton <nathan@robotics.net>wrote:> On Mon, 23 Feb 2009, Siddharth Wagh wrote: > > Hello folks, >> >> I am running Xen 2.6 under Centos 5.2 installation, and am trying to port >> Xen migration abilities to Infiniband.

Re: [Xen-users] Infiniband Drivers under Xen kernel?
Yes, but you have started openib service? (/etc/init.d/openib start) Open IB load a kernel module to allow system work with ib.... If you does not have installed all required packages, when start, openib exit with failed. O.K., you must install anothers packages, drivers module vendors for your IB cards! Go in package manager, search in "available packages", type ibverbs and go. Check interested packages for your card(s), (sorry, at moment I does not remember why categorized by vendor) and install it. ....retry service openib start. Bye, Enrico> Thanks Nathan.
