[CentOS-docs] how to submit corrections for virt-bridge-errors page?
Hi. This page saved me a lot of trouble today, when my Xen 3 multi-bridge setup stopped working after updated from CentOS 5.5 to 5.7: http://www.centos.org/docs/5/html/Virtualization-en-US/ch-virt-bridge-errors.html However there were a couple of errors in the script: use of op instead of OP (variable name mismatch) and use of .. ,, instead of ;; in the shell case structure. I can't tell if these errors are from redhat.com or from CentOS, and I couldn't find the Red Hat source. So I'm posting here just to do something in the general direction of improving this resource. Thank you! Love CentOS. Yours fondly, Aleksey ___ CentOS-docs mailing list CentOS-docs@centos.org http://lists.centos.org/mailman/listinfo/centos-docs
Re: [CentOS-virt] how to add file-based disk space to a guest
hi there, coming back on a old thread. My topic is rather simple : I want to attach a file-based hard drive to a linux guest. I want to understand differences between doing it with command line tools versus virt-manager GUI. - first, creating a disk image on the physical host: qemu-img create -f qcow2 /mnt/qemu_disk_images/disk1.qcow2 15G - then, appending a disk definition into the guest XML file: $ virsh dumxml myguest dump.xml (...) disk type='file' device='disk' driver name='qemu' type='qcow2' cache='default'/ source file='/mnt/qemu_disk_images/disk1.qcow2'/ target dev='vdb' bus='virtio'/ /disk (...) $virsh define myguest dump.xml Then I have to reboot (virsh shudtown + virsh start) the guest to have the new /dev/vdb device available. If I do the same operation from the virt-manager GUI (add hardwarestorageexisting storagevirtio-diskbrowse local file), the /dev/vdb device pops up into the guest, even without rebooting. Can someone tell me the difference between what I do and what the GUI does ? thanks Tom Trey Dockendorf treydock at gmail.com Tue Jul 26 19:44:06 EDT 2011 I'm not aware of a virsh attach disk command but if you duplicate the entries for the existing disk you can then add the new one...something like this... # virsh -c qemu:///system edit VMname disk type='file' device='disk' driver name='qemu' type='qcow2' cache='none'/ source file='/var/lib/libvirt/images/vmname_var.qcow2'/ target dev='vda' bus='virtio'/ address type='pci' domain='0x' bus='0x00' slot='0x04' function='0x0'/ /disk You will have to adjust the values of course. I'm following these documentations to add a file-based disk volume to a KVM guest under Centos 6.0 : http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualization/chap-Virtualization-Storage_Volumes.html as instructed, I created a pool then a volume, file-based, e.g : mkdir /mnt/raid/kvm_pool1 virsh # pool-define-as pool1 dir - - - - /mnt/raid/kvm_pool1 virsh # pool-autostart pool1 virsh # vol-create-as pool1 volume1 20G --allocation 15G --format qcow2 now I want to associate volume1 to my guest OS. Following this doc: http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualization/sect-Virtualization-Virtualized_block_devices-Adding_storage_devices_to_guests.html - why does this ask me to create a file with dd ? it's already been created before with the virsh pool commands, isn't it? Seems to me I'm bypassing the libvirt/virsh layer if I do that. - after that, the doc tells me to do some stuff with guest XML files. Is'nt there some specific commands provided by virsh to associate a managed Pool to a managed Guest ? - in this case, should I use the virsh attach-disk command ? thanks. -- Tom ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt

[CentOS-es] Emulación de teclado KVM
Hace algunas actualizaciones del host CentOS 5.X que no consigo instalar una máquina virtual bajo KVM con un correcto mapa de teclado español. ¿Alguien conoce la causa? ¿Cómo arreglarlo? Las versiones anteriores de libvirt y compañía (digamos, de cuando el 5.4 o 5.5 estaba al día) reproducían fielmente la distribución de teclado en los huéspedes. Ahora, levantando un guest de cualquier distribución, en modo texto, no hay dónde encontrar la barra (shift 7), la ñ, y muchos otros caracteres necesarios. Hoy dejé el 5.7 al día y tampoco pude lograr una instalación con teclado usable. El problema es con imágenes de varios OS (me ha ocurrido con CentOS 5.X, CentOS 6 y con un derivado de Slackware). Con este último, seleccionando qwerty-es, us-acentos, tampoco se consiguen barras ni eñes. En todos los casos estoy partiendo de un CD de instalación y procediendo con el ambiente gráfico de máquinas virtuales virt-manager.

If absolute 100% binary compatibility is not required, but admin-level compatibility and source-level compatibility with upstream EL is, Scientific Linux is covering that niche, and has their 6.1 out. And that's not a criticism of CentOS, either, as the binary compatibility testing CentOS is doing has its purposes. Again, glad there is CR out there. The rebuilding per se isn't the issue; testing against the upstream binaries for compatibility without running afoul of the upstream AUP seems to be the problem. I have a couple of servers on Ubuntu LTS; after experiencing a few issues I'd say go Debian stable rather than Ubuntu LTS, from experience, if you're going to go that route. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] read failed after messages of non existing harddisks
I would assume you have rebooted since removing the drives, in which case they should not be seen by cat /proc/partition, which is a representation of scanned disks during bootup, unless you have other drives still connected that you are not aware of? cat /proc/scsi/scsi should help in narrowing down which devices you are actually looking at. To bridge the gap when what partitions and scsi/scsi is showing, install package (if not there already) lsscsi and run command lsscsi.

No - I think the purpose was to provide updates that fall between releases but given that the 6.1 release hasn't happened, it has assumed the role you suggest, at least at some level. I too moved on to Ubuntu some 6 or so months ago because I could see that CentOS 6 was going to be a problem. While I can appreciate that the CentOS are doing what they can do given the parameters they have to work from, I can only see Red Hat killing off their base in order to protect their base. I'm all for a successful CentOS as I see it just helps the Linux Red Hat ecosystem to have them successfully re-spin the upstream product.

[CentOS] NSS ldap problems
I'm having trouble setting up ldap based authenication. I have a virtual (KVM) CentOS 5.4 box set up to authenticate to a 389 (fedora) directory server, and that works fine. However, I set up a virtual box running CentOS 6, and I can't get it to authenicate. I've run authconfig with the appropriate flags, ldapsearch properly finds the data, but I can't log in. /var/log/secure shows that it doesn't find the user, and as a test I came up with the following perl snippet: perl -e 'print join( ,getpwnam(testuser)),\n;' And it properly finds the test user on the 5.4 box, but not the 6.0 box. I've checked /etc/ldap.conf and /etc/openldap/ldap.conf and both seem about right. Here are the ldap related packaged installed on the 6.0 box: [root@vburntest02 ~]# rpm -qa | grep ldap openldap-2.4.19-15.el6_0.2.x86_64 pam_ldap-185-5.el6.x86_64 nss-pam-ldapd-0.7.5-3.el6.x86_64 openldap-clients-2.4.19-15.el6_0.2.x86_64 apr-util-ldap-1.3.9-3.el6.x86_64 Any idea what to check next?

Re: [CentOS] openldap missing modules
For learning purposes, I think the flat file is much easier to master. I thought Apple's Open-Directory was forked from an older version of OpenLDAP (perhaps 2.1.x). I gather that upstream 6.x and thus CentOS 6.x is using OpenLDAP 2.4.x and probably also dynamic configuration but I haven't installed upstream 6.x or any derivative distribution so I don't know for sure. Dynamic configuration was introduced in OpenLDAP 2.3 and it seemed to me that the book is using dynamic configuration but I could be wrong. It either references using 'cn=config' or it doesn't and that's the indicator of whether it is dynamic or not.

Re: [CentOS] ibm m1015 w/sandy bridge boot failure
On Thu, Oct 27, 2011 at 09:18:56AM -0500, Matt Garman wrote: I have a server running CentOS 6.0. Last night I replaced the CPU and motherboard. Old hardware: Supermicro x8sil-f + x3440. New hardware: Supermicro x9scl+-f + E3-1230. This is a new Sandy Bridge Xeon. Everything else remained the same, including an IBM m1015 SAS HBA. This is just an IBM re-branded LSI 92xx-8i (9220-8i specifically I believe), which uses the LSI SAS2008 chipset and the megaraid_sas driver. It worked without any issue on the old motherboard/cpu. However, with the new motherboard/cpu, the system makes it through the BIOS POST without any issue. But about half-way through the kernel initialization, it basically locks up. It will sit there for several minutes, doing nothing, then start printing out error messages (I was unable to get a screenshot or take note of the errors). But if I take the m1015 card out, the system boots quickly and without issue, as it always has. I saw this post[1] on the forums, which suggested that Sandy Bridge really needs 6.1, which, for those of us using CentOS, we can only get sorta close to by using the continuous release. So I did a yum install centos-release-cr ; yum update. I let everything install (there were no install errors or problems), and rebooted with the m1015 in back in the system, but the problem remains. So now I'm at a loss. Anyone have any thoughts? [1] http://www.centos.org/modules/newbb/viewtopic.php?topic_id=33878forum=56 SuperMicro actually has a FAQ[1] on a very similar issue: same motherboard, but an LSI 9240 RAID card (very similar to the IBM M1015, same actual chipset I believe), and CentOS 5.5. But the described problem is the same as mine. Simple fix: upgrade BIOS to v1.1a or later. Works for me!

Re: [CentOS] NSS ldap problems
One difference I ran into with samba authentication is in cent 5 /etc/pam.d/system-auth-ac is the file to change but in cent 6 its /etc/pam.d/password-auth-ac. I found that changes I made only to system-auth-ac in 5 had to be made to both system-auth-ac and password-auth-ac in 6. This was to have authentication work for things like ssh and sudo in centos 6. - Trey On Oct 31, 2011 8:16 PM, Jack Bailey j...@internetguy.net wrote: On 10/31/2011 4:46 PM, Craig White wrote: Here are the ldap related packaged installed on the 6.0 box: [root@vburntest02 ~]# rpm -qa | grep ldap openldap-2.4.19-15.el6_0.2.x86_64 pam_ldap-185-5.el6.x86_64 nss-pam-ldapd-0.7.5-3.el6.x86_64 openldap-clients-2.4.19-15.el6_0.2.x86_64 apr-util-ldap-1.3.9-3.el6.x86_64 Any idea what to check next?

[CentOS] redhat vs centos
I have been reading the threads on here with great ernest about redhat making a move to throw off centos compilations. I read some stories about microsoft wanting to work closer with centos http://www.theregister.co.uk/2011/05/17/microsoft_and_centos/ I have to update to centos 6 due to some needs of clients who need newer mysql and php (and installing them on centos5 was too hard for me). I am thinking of going ubuntu server but at the same time I have this feeling centos team will pull through, make a new method to streamline this, and redhat will back down and stop being REDa$$-hats. Redhat thinks us 'freebie' people will move to them to get the quicker updates and releases. I look at the pricing and I say they must be out of their minds. The server comes at 1,999 a year for 2 sockets and more than 4 guests...which is what I would need. The virtualization package, which may or may not be needed is thousands more. All for one server. that ain't gonna happen. Personally I am thinking of staying away from all red hat clones due to redhat's actions for my own security. The only thing on the horizon I see is ubuntu server as best supported and up to date. I am teetering tonight. I have downloaded it and am thinking of wiping my new centos6 install and trying it out. How do you all feel about this turn of events and what is your gut feeling on where this is going?
