Hi, After yum update on a Cent OS 6.0 IBM x3850 server to Cent OS 6.1, the kernel crashes on boot. I have googlet a little, and find that others have the same problem and there seems not to be a solution yet. The kernel that crashes is 2.6.32-131.21.1.el6.x86_64. If i boot the prior kernel 2.6.32-71.29.1.el6.x86_64 instead it works! Is it...

Hi all, I have searched the net and haven''t found a good answer so I hope perhaps someone here can help. I have an IBM x3850 (8863) that I am upgrading from SLES11SP1 to SLES11SP2, and at the same time XEN is being upgraded as part of the distro. The server is used as a Xen host for up to 6 guests. Anyway, the server boots fine with the SLES11SP2 default kernel, and the trace kernel, but, fails on booting to the Xen...

...hat may be important for you and your readers. I have many different Dell model, they all worked well with PXE booting however not for E5510. I noticed that using "LocalBoot -1 or 0" doesn't work well. What I did use for Latitude E5510 (Bios A06) was same to "LOCALBOOT on IBM x3850 X5" COM32 Chain.c32 Append hd0 0 Not "Append hd0" It works and boots to local disk without any problems.

Hi, I am new to virtualization and I am having the obvious hassle of choosing between Xen and KVM. Can Xen experts help me with this? Regards, Arindam _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users

Hi all, My server is IBM x3850 X5 and use Broadcom UNDI PXE-2.1 v5.2.4 stack. When I choose localboot to boot from the harddisk, the system willnot boot up then still trying to boot from PXE. Several times later the PXE boot procedure is crashed with words as I attached. Does anyone have any good idea? Thanks very much. Eric...

I notice for some reason you can no longer get pre- builds from the listed place. Can you point me to a better location? UEFI boot isn't working on my hardware so I'd like to try something newer. It is an IBM x3850 X6 if that's interesting info. ____ *Note: UMDNJ is now Rutgers-Biomedical and Health Sciences* || \UTGERS |---------------------*O*--------------------- ||_// Biomedical | Ryan Novosielski - Senior Technologist || \ and Health | novosirj at rutgers.edu<mailto:novosirj at rutgers.edu&g...

Holding the vblk->lock across kick causes poor scalability in SMP guests. If one CPU is doing virtqueue kick and another CPU touches the vblk->lock it will have to spin until virtqueue kick completes. This patch reduces system% CPU utilization in SMP guests that are running multithreaded I/O-bound workloads. The improvements are small but show as iops and SMP are increased. Khoa Huynh
