RE: [CentOS-virt] Need Help with Xen Please
Hello Kai: Thank you for your feedback. I apologize for not using the right terminology. As mentioned I followed the tutorial at http://www.howtoforge.com/centos_5.0_xen so that shows all the commands I used. When I tried to install a guest/domU I get the previous mentioned error. Virt-install doesnt seem to work as it seems to require a console which I do not have. All I have is root access to the server via SSH (not in same physical location as server) Jason -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Kai Schaetzl Sent: Sunday, November 16, 2008 4:31 A To: centos-virt@centos.org Subject: Re: [CentOS-virt] Need Help with Xen Please Jason Taylor wrote on Sat, 15 Nov 2008 17:00:46 -0700: One thing to note is that the base Xen installs fine it seems but when trying to create the virtual instance (domU) it says it cannot connect to the console. Then try without making it connect to the console. (I may have misunderstood what you mean by create, note, create means *starting* an existing VM. see below.) I looked at the how-to, it uses virt-install. That works very well. What exactly did you install as a domU? What where your commands? And when do you get that error, when you run virt-install and it wants to attach to the console or once it's finished and you start the VM up? One thing: you want to use the Xen 3.2 rpms provided by xen.org for serious production work on CentOS and not the one coming with CentOS. Suggest you read the archives of the list for all tips and caveats.

You need to ensure that you have access to your local graphical interface from the remote server i.e. that you have a valid DISPLAY variable set.

Sometimes ssh -Y works when ssh -X doesn't. Over time I've started using ssh -Y as it always works. If the server is setup correctly, it will not allow you to ssh as root, you'll need to ssh -Y as yourself and then su -. When you use the su command you might loose the DISPLAY variable, in this case simply re-establish it and all should work. If you workstation is Linux, you have an X-Display running.

You want to run virt-install without any parameter and answer all the questions. In that case I need to ask what OS you want to install. And, although you don't want to, have a look at man virt-install and then try an install that uses the command -line parameters instead of asking questions. Also, earlier you wrote: Xend does start and I can do everything listed in the tutorial until I get to the virt-manager part. So, is your problem now with virt-install or with virt-manager? Does your VM get created? Can you start it with xm create name of vm? Do you see it running in xm list? The main point here is that it's not clear from the beginning if virt-install cannot connect to the console and thus you cannot install the OS or if it all creates just fine and you later cannot attach to the running domU console.

Re: [CentOS-es] 2 ISP mas una Lan
2008/11/17 Nino Bravo [EMAIL PROTECTED]: Hola Haber aqui voy a ser mas claro tengo un linux centos 5.0 pentium 4, 1 giga en ram, que hace de nat + proxy + gateway + cbq + kernel-2.6.18-92.1.13.el5, disco duro de 80 gigas, 1E1 sincrono de xISP, 1Mbit sincrono de yISP, con 150 clientes. Lo que quiero es unir esos anchos de banda ya que con ifconfig solo puedo tener uno a la vez, lo de booding no me convence no se si sea de pronto la solución, otra duda es como asigno las ips ya que yo lo hago en /etc/sysconfig/network-script/ tanto eth0 eth1 eth2, Hasta donde conozco no hay diferencia entre hacerlo con ifconfig o con ip, salvo en lo referente a interfaces secundarias que solamente se pueden definir con ip. Unir los anchos de banda es una expresión un poco relativa (para cada conexión separada NO vas a poder usar más ancho de banda que el de un único enlace; aunque sí se pueden distribuir las diferentes conexiones entre los dos enlaces, haciendo que el ancho de banda disponible AGREGADO sí sea la suma de los dos enlaces). he creado conexiones virtuales como es logico para meter ciertos rangos de ip Ej: eth1:1000, eth1:1001. Por qué es esto, Nino? Se trata de VLANs? O es una definición que se necesita para CBQ? ETH1 - CLIENTES (192.168.XX.XX) (192.168.YY.YY) (192.168.ZZ.ZZ) ETH0-ISP1 ETH2-ISP2 En esta notación, los grupos entre paréntesis son VLANs? O simplemente grupos de equipos que quieres que tengan diferente tratamiento? Quisiera saber como hago para decirle al linux ej: (192.168.XX.XX) (192.168.YY.YY) sale por ISP1 (192.168.ZZ.ZZ) SALE POR ISP2 Con ruteo por origen: cada proveedor/interfaz de salida del router tiene asignada una tabla de ruteo; a cada paquete que ingresa al router se lo afecta con un tag o indicador de tabla según su IP de origen; y se aplica esa tabla para rutear ese paquete. Esto es lo que se explica en el documento que te apuntaba (recorriendo con el link Prev va a aparecer más info; lo recomendable es leerse por lo menos el cap 4) COMO ME PUEDE AFECTAR ESTO AL CBQ, Si no entiendo mal, el CBQ es una disciplina o politica de desencolado de paquetes de una interfaz, así que en principio seguiría conformando el tráfico hacia cada proveedor de la misma manera que antes. Lo que cambiarías con el ruteo por origen sería qué paquetes se presentarían ante cada interfaz para competir por el desencolado bajo CBQ. Como el patrón de tráfico ante cada ISP va a cambiar una vez que establezcas ruteo por origen, puede que haya que reconsiderar la política de CBQ que apliques en cada interfaz. Y SI HAGO SALIR A LAS DIRECCIONES IPS POR X ISP COMO HAGO PARA QUE RETORNE POR EL MISMO ANCHO DE BANDA. Por la misma conexión? No hay más remedio que sea así, porque gracias al NAT los paquetes saldrán con la dirección de origen de tu interfaz y a ella volverán gracias al ruteo del resto de Internet. Este manual me parece que es la solución: http://lartc.org/howto/lartc.rpdb.multiple-links.html pero no entiedo donde asigno las ips si ya no lo hago con ifconfig o que es lo que debo de hacer, por favor un poquito mas claro para ver si puedo solucionar. Tampoco entiendo bien esta pregunta... Ifconfig te permite asignar un IP a una interfaz, normalmente al momento de arranque, y casi nada más. Lo restante (ruteo por origen o conformación de tráfico) es trabajo con los comandos ip o con tc. Naturalmente vas a necesitar ifconfig para configurar las interfaces del router... o te refieres a las de los clientes? No es importante cómo las configures, solamente que tengan los valores que necesitas. -- Eduardo Grosclaude Universidad Nacional del Comahue Neuquen, Argentina ___ CentOS-es mailing list CentOS-es@centos.org http://lists.centos.org/mailman/listinfo/centos-es

PUNTUALMENTE PORQUE SI ES PARA EL ENVIO DE CORREOS MASIVOS TE ENVI EL

1. Lo primero será generar un fichero en el sistema el cual tendrá como
contenido una lista de los usuarios del sistema a los cuales se quiere
enviar un mensaje. Este puede localizarse en cualquier lograr del sistema,
como por ejemplo /etc/mail/allusers. Puede editarse el fichero
/etc/mail/allusers y añadir individualmente cada usuario que se desee
conforme esa lista o bien, si se quiere añadir a todos los usuarios del
sistema, ejecutar lo siguiente:
awk -F: '$3 500 { print $1 }' /etc/passwd /etc/mail/allusers
2. A continuación, debe editarse el fichero /etc/aliases y añadir al
final del mismo:
allusers: :include:/etc/mail/allusers
3. Al terminar solo debe ejecutarse el mandato newaliases o bien
reiniciar el servicio de Sendmail (el guión de inicio se encarga de hacer
todo lo necesario).
4. Para probar, solo bastará enviar un mensaje de correo electrónico a
la cuenta allusers del servidor.

I have 2 Dell PE860 servers with 8GB ECC DDRII RAM as well, and they're both giving RAM problems. I had top swap-out the RAM 2 times with the suppliers already, and swapped out a motherboard on the one of the servers. Honestly, ECC isn't my favourate to use. At the same time, I have about 8 servers with cheap Gigabyte motherboards and non-ECC RAM, which have been running for close to 4 years now, without any hickups at all. It's the first time I try the Intel board, since it's supposed to be a step-up from the desktop boards, and has 4 memory slots as apposed to only 2. The server had the same problems when I only had 4GBM RAM (2 slots used 2 slots open), so I don't think that the capacitive load is the problem here. Right now the server is still at the datacentre - which is 2 hours drive there back with traffic, so I'm going to get it later today / tonight, as soon as I've moved all the data across to the slower gigabyte server, and then I can try the RAM timings thing in the BIOS.

HTH, Filipe ___ Hi Flippie, I have checked the BIOS settings, purely cause the new HDD was installed on a machine withou AHCI settings, so I had to change the settings in the BIOS to nativ IDE mode (the only other mode this motherboard supports). The reason why I'm suspecting the MB / RAM / CPU is that I already swapped the HDD's out, and reinstalled CentOS - first it was x64, now it's i386 (well, i686 as per uname -a). The only serivce that runs on the host node is HyperVM (which include the XEN tools, PHP, Apache, MySQL. I have the exact same setup on a few other machines, using Gigabyte motherboards + 4GB RAM. Other than that, the HDD's are the same, the OS is the same, and HyperVM is the same. I basically run yum upgrade once a week on all the machines. The only difference is this one has an Intel DG35EC motherboard with a Q9300 Quad Core CPU on it, which is supposed to be more power efficient than some of the Core 2 Duo CPU's on the other machine. As a matter of interest, all 5 Virtual Machines have been running on a Gigabyte motherboard + i6450 CPU + 4GB RAM since yesterday, and it's very very stable. So, my thinking is, it's the motherboard. It could also be the RAM, but I'm not 100% sure yet.

This is especially true when the machine under load would have both the CPU and the memory taxed but then during the testing we could only really tax one or the other using the existing tools.

[CentOS] CentOS 5.2 with IBM SERVERAID 6i
I need to install CentOS 5.2 on a IBM Server xSeries 226, which comes with a IBM SERVERAID 6i RAID card. I think it is not a true hardware RAID card. I has, nevertheless, an interesting feature: 128MB of cache with battery backup.

If both solutions are in fact Software RAID, is there any particular reason to prefer one of the methods?

Until then, you may well be stuck with some more bleeding-edge release. That's true, but, still, if XP can handle it, it seems as though CentOS 5, which is six years newer than XP, should be able to handle it OTTOMH mhr But windows drivers usually load and probe the hardware on install, but linux usually depends on the PCI id's to load modules. So windows will try and load a driver, and if it doesn't bomb, record that it works and keep using it. The linux install effectively looks at the PCI id numbers and looks for a match in the /lib/modules/modules.* files. A linux driver can sometimes be coaxed to load just by editing one of these files, but not always. Some of the kernel patches are just edits to the modules.pcimap file. -- MailScanner is like deodorant...

I have a problem with one of my machines, and have narrowed down that it could either be the CPU, RAM or motherboard, but before I take it back to the suppliers, I need to know what is wrong. They will switch it on, and see that it works. But it's not taking the load that I expect it could. In fact, it's not taking the same load as a machine with a Intel E6750 Core 2 Duo 4GB RAM. This server should be 2 - 4 times faster handle 2 - 4 times the load of the E6750, yet it doesn't and I need to know why. I don't appreciate being told that the hardware I have if inferior. Does the board recommend a certain memory config? I have had systems that specify a ram module down to the part number, and others just don't work the same. Some boards can be real picky, and also some boards don't have enough heat sync on their supporting chips and need a little extra ventilation. -- MailScanner is like deodorant...

Re: [CentOS] Re: how to debug hardware lockups?
Rudi Ahlers wrote: Sure, I understand that. But then again, on my Dell servers, when I have problems, I sit with the same issues. And those expensive motherboards doesn't give me anything more than the cheaper ones. In fact, when the RAM failed on the Dell's, they were unusable untill I could get new RAM from a different supplier. With the cheaper board, I drive down to the first PC shop and get new RAM. I suppose it depends on what dells you have. On the latest 1950 III systems we have they have moderately good diagnostics similar to HP systems. The system log tells me what DIMM module is spitting out errors so I don't need to go through the trouble of narrowing down which one(s) is bad. I only started using Dell recently since I started my new job in March, before that was mostly HP and Supermicro. HP certainly has great quality stuff though you do generally pay quite a bit more for it. Depending on what the server is doing would depend if I'd really push for that level of quality. Certainly anything that is a single point of failure I would want on a higher quality system. I'm not sure if Dell's motherboards go so far as to having diagnostic LEDs on them to point out what part is faulty. HP has been doing that for a long time now. The latest HP G5s port the LEDs to the front of the chassis so you don't even have to open it up or load any software you can just look at the front and see if a DIMM is going bad or a voltage regulator, or a PSU, or a CPU etc. Earlier systems just had a generic health LED, which would say good/degraded/bad. But it couldn't give any information as to what was causing the problem. Granted not as useful for a remote location if nobody is on site to look at the LEDs, though for many smaller places that actually do have people on site on a regular basis it's real handy. nate ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[EMAIL PROTECTED] wrote: My question now is: what would be the better way to implement RAID 5 on this server? Should I use the detected array and respective driver or should I delete the array and go for Linus Software RAID? I've installed RHEL 4 on several IBM eSeries servers with ServeRaid controllers and I despise them. They fail too often and often don't tell you that they are having problems until it is too late. My suggestion is to use Linux software for your RAID array, and bypass the ServeRaid controller entirely.
