I have been searching the web for a few hours and have not had any luck finding instructions on how to setup Xen HVM Dom0 on a CentOS 5.6. I have a test server with a stock install of CentOS 5.6 that support AMD-V.
View 3 RepliesI just install xen and kernel-xen version 2.6.18-194.26.1.el5xen, booting into the xen kernel dom0 shows me continous colorful scrambling and scrolling. I can ssh to dom0 and get correct display but the dom0 console is where it shows the colorful garbage scrolling. i have the Supermicro X7DC motherboard with a XGI Z9 graphics card. GUI is not installed and I don't have the rhgb parameter in my grub.conf. My grub.conf is plain and unmodified.

Problems with xen 3.1.2 creating and installing domU CentOS 5.5 I am trying to do a virt-install --prompt --paravirt, and the install error out while trying to download install RPMs. I have googled for xen centos virt-install and various permutations. I have found similar howtos for 5.4 and 5.3, but they resulted in the same outcome. I did find several posts with similar issues, but no solution was posted.[URL]..

I installed a new squeeze serverXen Hypervisor runs the server as Dom0 anda virtual Windows XP.The server runs samba, postfix, dovecot, squid, cups and hylafax with a Frritz ISDN card (module fcpci.ko).The used memory of Dom0 rises slowly (about 5MB /h) until the system crashes.As a workaround i installed a reboot every 24 hours.htop shows normal behavior.The system is already in production, so i can't stop services to track this bug.I need some hints how to debug the running system to find out, where the memory gets lots.
View 3 Replies View RelatedI would like to compile a custom xen dom0 kernel. I installed a Debian Squeeze with precompiled xen kernel, and it works fine, but i would like to compile a custom dom0 kernel from source. I tried install kernel source apt-get source linux-2.6 how can I patch this kernel source with xen? but i alway see only the domU kernel params.
View 3 Replies View RelatedI've got a fresh install of Squeeze on a 32bit host and I have been unable to boot into XEN/dom0.The Xen Kernel is "linux-image-2.6.32-5-xen-686" (pvops) and Hypervisor is xen-hypervisor-4.0-i386.The system default installed with grub2.It boots quite happily in normal mode, using the above Kernel, but just reboots itself if I try run it as Xen/dom0. (reboots within a second of pressing <enter> ... there is no messages displayed on the screen that I have noticed)The relevant menu (generated by /etc/grub.d/20_linux_xen) entry for running Xen is as below;

I have an etch-based Xen server that has several Xen domU's on it. All the domU's are etch or lenny based, but I'd like to install a karmic guest. I use xen-tools to install my domU's - e.g., xen-create-image --debootstrap <etc.>After much googling, I've found bits and pieces of info that have gotten me closer to the goal, but the debootstrap script I have is for hoary (I think etch came with this), and I'm pretty sure this won't work.
If you have been able to successfully install a Karmic guest on an etch or lenny host, I'd be very grateful for pointers.

View 1 Replies View RelatedI have two servers, both running CentOS, but one running Cpanel as the control panel and the other running Webmin.
I would like to sync the web folders using rsync. However, when I sync the files from the Cpanel host the permissions look as follows:
Code:
But that doesn't work on the Webmin server which needs the following:
Code:
It seems the Cpanel install has the group as 'nobody' whilst webmin has it the same as the file owner. I can fix this by running:
Code:
But as the file transfers will be frequent, I don't want the files to be inaccessible until chown is run.
So, what I really want to know is - how can I change things on the 'webmin' server so that files with ownership owner:nobody will run?
I built a home server (NAS/WWW/SSH/media server etc) and chose CentOS 5 as the OS (stability, easy of configuration).I was just about to start tuning the power consumption when I realised that the kernel CentOS uses is so "old" that it does not support the latest reduced power consumption enhancements that Linux has achieved in big strides in the recent past (we are probably still talking 6-12+ months ago e.g. tickless kernel)..
So my questions; 1) I know CentOS was maybe not meant for home servers (certainly its not its primary purpose), but if it is, any ideas of what kind of power consumption it takes (I know its relative) and if there are particular power consumptions that are worthwhile?
2) Do you recommend me compiling my own 2.6.21+ kernel from kernel.org or am I just likely to have compatibility issues (I really did not want to do that) or when is CentOS 5.4 supposed to have a newer 2.6.21+ version kernel?
Was it wrong of me in principle to choose CentOS for a home server when I am power conscious? (I don't have a low-power VIA processor either but a P4 so I am really just hoping to make do with software changes).
I have a few mail servers, a mail log server and a web server running on Centos 5. Now I have a task: to avoid accidental crashes on the production servers while installing updates, my boss asked me to do clones (these clones will all be VMware virtual machines) of the servers (EXCLUDING the actual e-mails and log contents) and then to run those clones on VMWare Server. This way, first I will install and test updates on the clones and - if they will be running without crashes - I will apply the updates on the real production servers themselves.
I have already installed VMWare Server 2.0 I have a few questions: How do I build the virtual machines to exclude the actual mail files and mail logs? Can I use VMware Converter for this purpose, or do I have to use another program? How do I actually do this cloning? Is there a tutorial on how to do this?
If I ssh from my laptop (running F10) to the server (centos 5.2) it asks for the password, but everytime I enter the correct password it says incorrect password. when I do the same from the server to my laptop I can get in just fine. I think my passwords are stored as ssha in the LDAP (I tried clear passwords and that dosen't work either).

I've installed CentOS 5.3 on a machine, and I need a Samba version 3.2 or higher. Since 3.4 is out, I thought I'd grab that. But, "yum list|grep samba" gives me only version 3.0.33. Is there a package of Samba I can grab that will upgrade the 3.0 installation so that I don't have two laying around? If not and I need to compile from source, do you have any suggestions for what arguments I should give configure? I'm not used to Linux coming from the BSD world

View 3 Replies View RelatedI am running an application that requires use of my /etc/hosts file. In it, I have my machine name and its LAN ip address. The program creates a service on a specific port, then attempts to connect to it based on the host name. So my hosts file has to be correct.I added the nameservers to resolv.conf and now my application will not run. My guess is that the computer is checking the name servers first, timing out then checking the hosts file.Is there a way I can tell the system to check the hosts file first, then DNS. I thought it should behave that way by default, but it does not appear to.
