kernel-2.6.32-131.2.1.el6.x86_64 & Xen DomUs.
Hi all, In the latest batch of updates, I installed kernel-2.6.32-131.2.1.el6.x86_64 via a 'yum -y update'. It seemed all of my 5 Xen DomUs running SL6 failed to boot upon rebooting. It looks like all of these systems failed at roughly where switchroot is called. Interestingly, I could recover from this by shutting down the DomU, mounting then chrooting the DomUs filesystem and issuing: # rpm -ivh --force kernel-2.6.32-131.2.1.el6.x86_64.rpm Not sure how widespread this issue is, but I had a 100% failure rate on Xen DomUs. The one bare metal system I updated did so with no errors. -- Steven Haigh Email: net...@crc.id.au Web: http://www.crc.id.au Phone: (03) 9001 6090 - 0412 935 897 Fax: (03) 8338 0299

Installing SL6 on VMware player
Has anyone managed to install Scientific Linux 6 (SL6) on VMware player? I tried installing it today and was unable to get it to work: * SL6 can not see the SCSI virtual disk * While the IDE disk works, SL6 either freezes on install or update. One time, I got a kernel message about a disk I/O error before the system froze up. I have given the guest 512MB of memory and the host is an Intel Atom N455 without VT-x. I am able to install SL6 on VirtualBox, and everything works (albeit more slowly than I would like) - Sam

TESTING - kernel update for SL4
Hello, Traditionally the first kernel for a minor update is full of bugs so we generally don't release it in regular security area. Traditionally The Upstream Vendor (TUV) releases a new kernel to fix those bugs fairly quickly. The 2.6.9-100 kernel for SL4 seems to break the tradition. It's been four months and nobody has complained about a major bug. And TUV hasn't released a new kernel to fix the kernel. So we will be releasing this kernel into the general security updates tomorrow June 14, 2011. We are putting it testing for those who have not yet tried out this kernel and/or want to give it one last test. To test or update SL4 --- yum --enablerepo=sl-testing update kernel\* or you can download rpm's by hand at http://ftp.scientificlinux.org/linux/scientific/40rolling/testing/i386/RPMS/kernel/ http://ftp.scientificlinux.org/linux/scientific/40rolling/testing/x86_64/RPMS/kernel/ kernel-2.6.9-100.EL Thanks Troy Dawson -- __ Troy Dawson daw...@fnal.gov (630)840-6468 Fermilab ComputingDivision/LCSI/CSI DSS Group __

I thought perhaps that someone may have come across this with SL56 Here in Sydney, we installed slc56 x86_64 on a Dell Power Edge R510 with 48Gb of RAM. The problem we have is that once the os is installed slc56 top, free and vmstat only reports 32Gb. All the yum updates were performed. To check we booted with the rescue mode, SLC 5.6 and all the commands report 48Gb . A further check we installed RHEL 5.6 x86_64 it reports 48Gb . Is there some tweak to the kernel that needs to be done? Or any cause to the problem. Any ideas are much appreciated. Cheers, Aldo Is this machine being a virtulization host? I know that on SL5 for xen hosts (I haven't verified it for KVM hosts) you only see the amount of memory that the host has left, not the total amount of memory. The best way I found to look at the full memory in this situation was to do a "xm list" which lists all the xen client's memory, as well as the hosts.

Hi all, It's a little bit off topic, but I thought that SLC was the CERN variant of Scientific Linux. And SL 5.6 is not yet released. I saw that SLC 5.6 was released months ago and is now the official release for CERN. So, for my information (and perhaps others), why is there a SLC 5.6 release and not yet a SL 5.6 one ? Thanks for the clarification ! Alain Short clarification, I'll let someone from CERN clarify longer if they want. SLC 5.6 has all the updates and packages from SL 5.6. Those packages have already passed our tests, and I assume CERN's tests. The reason SL 5.6 isn't out yet is due to two installer problems, not package problems. So if CERN modifies their installer different than plain SL, it is quite possible for them to beat the plain SL out with a release.

Red Hat has support for PPC-64 but CentOS was never able to complete theres into a booting format. The Fedora PPC-64 project does have people working on it but they are usually several releases behind. To answer people's questions I think it was Itanium RHEL dropped for 6.
