Hi everyone,
I only recently subscribed to this list and hope you can shed some
light on the following error. I created a VM on my Centos 6 KVM
machine, used a qcow2 image and wanted to create a snapshot via 'virsh
snapshot-create' command:
//
[root@kvmhost ~]# virsh snapshot-create server01
error: internal error unable to execute QEMU command 'savevm': The
command savevm has not been found
\\
I googled before the post, found some [0] threads [1], but could not
find an answer how to solve the problem. If the kvm-qemu lacks the
support of a savevm monitor, how can I add one? Do I need to recompile
kvm-qemu with special flags or is simply a RPM package or a module
missing?
Thanks in advance,
- Jason

I ran into this too. Unfortunately I haven't found a solution either,
but
here's an interesting bug report that shows this effects all the way up
to
Fedora 15, https://bugzilla.redhat.com/show_bug.cgi?id=727709. The one
fix
mentioned 89241fe0, I've actually patched into the CentOS libvirt RPM,
but
from testing it doesn't seem to be enough. I now can run the
snapshot-create
command without error, but nothing appears to happen. I've tested
creating
files, taking a snapshot, deleting files and reverting and nothing comes
back or changes. Also the qcow2 images don't change at all during this
time
either. I'm working on applying the other commits mentioned in Comment
#4,
but am running into problems since most of those commits are 0.9.0+ and
I'm
patching CentOS's 0.8.1.
I'd love to know if anyone actually has snapshots working in CentOS 5 or
6.
This is kind of a critical feature to the entire virtualization process.

be the relevant debug info. If the full debug is desired let me know (it's
like 1000 lines long spanning 1 second)

This was with libvirt-0.8.7-18.el6_1.1 from CentOS 6 CR. I restarted the
libvirtd daemon after the upgrade, still same result. Restarted the VM also
, still same. I only updated libvirt, libvirt-client and libvirt-python
from CR, haven't done a full system update. I'll try the full update next,
but any suggestions are welcome in the mean time.

Between buying Qumranet (http://www.redhat.com/promo/qumranet/) and now Gluster (https://www.redhat.com/promo/storage/) it is clear that Red Hat aims to become a provider of a complete independent virtualization stack and is unlikely to support competing products directly. The question is what does Xen offer that KVM cannot provide? Looking at the slides of the KVM Forum 2011 (http://www.linux-kvm.org/page/KVM_Forum_2011) there seem to be many interesting improvements in the pipeline so at some point the question really is why hold on to Xen at all when there is not real reason to?

Hay muchos suscritos desde hace mucho tiempo, que no postean y sólo reciben mails... ahora toda persona que desde aprox mediados del 2010 escribe a la lista, se le quita el bit de moderación. Solamente se le pone si su cuenta es usada para enviar spam (hay quien sigue usando windows y se contamina y su cuenta es usada para enviar mails con spam, etc). Revisa si te has desuscrito y suscrito nuevamente, para el sistema cuenta como una nueva suscripción. A todos los que postean regularmente, sin excepción, a todos los que postean, sin excepción, se les quita el bit de moderación. Recuerden que el bit de moderación fue activado cuando comenzaron a llegar mails no relacionados a la lista ni autorizados por los que enviaban (virus, spam) y realmente ha sido útil, todos los días nos llegan a los moderadores mails de spam que quedan filtrados de nuestro lado, desde spam hasta estoy de vacaciones hasta el 31 de febrero, te deseo suerte y te respondo luego. Cómo funciona la moderación? No tengan pena escribir, simplemente el primer mail que envíen nos llega a nosotros primeramente, es analizado por mí o por Roger (roger.. vives?) y si el mail es definitivamente spam o algún tipo de tema no relacionado con la lista (por favor! Sólo no permitimos mails automaticos de vacaciones, mails claramente spam o temas muy por ese estilo) simplemente entonces el mail no es permitido, incluso le rechazamos para que el que origina el mail de vacaciones por ejemplo se dé cuenta de lo que hizo. Si el mail es relacionado con los temas que se están tratando, pues simple y llanamente se dá paso y se quita el bit de moderación al usuario. En tu caso no es ninguna de las anteriores.. entonces algo pasó, quizá ese día que posteaste no se te quitó el bit de moderación porque Roger andaba dormido o porque yo estaba almorzando, etc. Yo creo que por probar te desuscribiste o algo parecido porque sí tienes varios posts en los últimos tiempos. saludos epe ___ CentOS-es mailing list CentOS-es@centos.org http://lists.centos.org/mailman/listinfo/centos-es
Re: [CentOS-es] Raid5 con LVM en Citrix XenServer
Por lo general hay muchas placas madre que traen sata raid on board, que en realidad solo te entrega un raid por software, lo cual como indican no es recomendable para ambientes de virtualizacion. Para dar uso de este tipo de controladoras en linux debes utilizar fake-raid, pero incluso en la documentación de CentOs recomiendan desactivarlo y si necesitas un raid por software es mejor opción crearlo con mdadm. http://wiki.centos.org/HowTos/SoftwareRAIDonCentOS5 Saludos.

Re: [CentOS-es] Raid5 con LVM en Citrix XenServer
a mi me suena a que estas usando una placa para desktop con capacidad para implementar raid, segun tengo entendido este tipo de configuracion no es soportado por linux, si este es tu caso deberias adquirir un adaptador para Raid compatible con linux. En todo caso si es un servidor lo que estas usando y si tienen adaptador de raid integrado, verifica el chipset del dispositivo, algunos basados en intel no son compatibles con linux, digo esto por que tengo un servidor cuyo raid tiene esta configuracion y no es reconocido por linux.

[CentOS-es] Listar versión obsoleta de paquete (up2date)
Buenas a todos: Estoy intentando utilizar up2date en unos centos 4 y (un red hat 3), pero no logro dar en el palo. Lo que necesito es que up2date me de un listado de versiones obsoletas para poder instalar alguna de ellas, no importa cual sea mientras no sea la ultima. Esto es para un testeo de distribución de parches, asi que no es una opción valida bajar cada rpm a mano y luego instalarlo. Esto mismo en 5 y 6 lo hago con yum (yum list all), al que he tenido que modificar un variable en el yum.conf (showdupesfromrepos=1 ), Pero a pesar que modifico la variable que supongo cumple la misma función en 4 (showAvailablePacka) no consigo que me muestra las versiones obsoletas. Alguno tiene una idea si sobre esto o si debo encarar el problema de otra forma?. Saludos, ___ CentOS-es mailing list CentOS-es@centos.org http://lists.centos.org/mailman/listinfo/centos-es

HOWEVER, it's very much in RHEL6 and CentOS6. While I don't think OP should necessarily be using inittab that way, there are certainly commercial pieces of software (I'm looking at YOU Tivoli Storage Manager!) that want to use inittab for keeping crash-prone things alive. /etc/init is the place for this, however the format is different...

I would like anything stable and secure beyond Firefox 3 but can't find tarballs for anything other than 7.0.1. I'm running Firefox-7 on Centos 5.7. Back on (I think it was) Firefox 5, I found that firefox had dependencies on libstdc++ that weren't met by the lib on centos. I went digging around on my system and found that some other programs had their own local copies of libstdc++, so I tried copying them, once at a time, into the same directory where mozilla itself keeps some libraries. After a little cut-n-try I found one that worked. I've not changed it since, it still works. Not sure how to discover the version # of the libstdc++.so.6 I am using, but dong some 'finding' on my system I see that there is a copy of libstdc++.so.6 in two different places that are the same size as the one Firefox is ucing. they are 970680 bytes, and the filename is libstdc++.so.6.0.9, FWIW. I also note that Centos-6 works with Firefox-7 without having to do what I described above.

[CentOS] CentOS 6 USB changes
Ok, I just managed, after much effort, to rebuild my USB key to install CentOS 6. There are a number of changes. Partition the USB key, but make partition 1, Win 95 (FAT32) (I think that's partition type b), bigger. I made it 500M. The rest should be ext3 (or whatever). Format the partitions. Make sure to toggle the bootable flag on partition 1. syslinux /dev/DOS partition When you're done, the DOS partition should look like this: ls -laF /mnt /boot/ /ldlinux.sys /syslinux/ Under /boot is /grub, and it's contents. Make sure you create a grub.conf to put in there. If syslinux didn't put it there, mount your .iso, and copy /mnt/iso/isolinux into there, then rename /syslinux/isolinus.cfg to /syslinux/syslinux.cfg. I put a grub.conf here, too: cat /mnt/disk/syslinux/grub.conf #debug --graphics default=0 splashimage=@SPLASHPATH@ timeout 5 hiddenmenu title @PRODUCT@ @VERSION@ kernel @KERNELPATH@ initrd @INITRDPATH@ title Install system with basic video driver kernel @KERNELPATH@ xdriver=vesa nomodeset askmethod initrd @INITRDPATH@ title rescue kernel @KERNELPATH@ rescue askmethod initrd @INITRDPATH@ On the second partition, copy your .iso images. Then copy /mnt/iso/images there. You should be good to go. NOTE: during the install, if you make any partitions encrypted, it will hang when it's done formatting, so reboot, and tell it to install again, and then not to format. It will start, then ask for the password, then actually go through the install. mark ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
