similar to: XEN Paravirtualized CentOS5 beta on CentOS5 beta

Hi, I am in a process to virtualize an existing non-virtualized CentOS5 system. Everything else works fine except X: virt-manager's console just hangs after bootup. I can use the text console though and what I see in X server's log is the error message "screens not found". The only graphics related setup I've done is in the domu config this line: vfb = [

For those of you who are going to do the update from the centos5 beta to centos 5 proper despite the warnings, this is a(n incomplete) list of instructions for how to accomplish this 1. Get yourself into runlevel 3 (telinit 3 from terminal) as the dbus update will die if you're in X. 2. Setenforce 0 # turn off selinux as there have been some unconfirmed reports that it will interfere with the

I have just successfully installed CentOS5 beta from CDs. No major issues so far, but it is still too fresh to say anything. The machine I used is peculiar. By peculiar I mean it won't boot if I use grub (this is a long story by itself). So, I manually installed lilo to boot the system. The only problem is that I could not use kdump. It produced an error saying "No bootloader config

I've got a Dell Latitude D620, dell docking station and a Dell 2007WFP (20" widescreen lcd). With XP I had the laptop screen and the lcd working as dual screens. But for the life of me I cannot get CentOS5 to work with dual screens. Anyone have this working? I would greatly appreciate any assistance. -matt

I have a server with 6 gigs of memory. CentOS5/Xen sees only half of it. Could someone advice me how to get it recognize all my memory? I have installed 32bit CentOS5 and I'm running kernel-xen-2.6.18-8.1.8.el5. This kernel should have PAE support: $ grep PAE /boot/config-2.6.18-8.1.8.el5xen CONFIG_X86_PAE=y But xentop reports only 3 gigs of memory: Mem: 3145148k total, 2400512k used,

Hi all, I'm setting up a virtualization software on CentOS, using virt-manager, KVM, qemu and Xen When I want to create a VM, paravirtualized mode isn't possible (ie it is grey) What should I do to use xen paravirtualized mode ? i figured that xen is not running but /etc/init.d/xend start doesn't work xen and xen-kernel are installed on the machine (rpm -qa | grep xen replies : xen

Hi all, I have problem reaching 1Gbps network speed with dom0 / domU (paravirtualized) on my centos5 installations. The fastest speed I measured in domU was about 800/600 receive/transmit Mbps, dom0 being a bit slower. I'm using bridging (eeither with default xen/centos network-bridge script or with my own scripts assigning vlans to bridges). Is anyone experiencing same network slowdown? Or

Package: xen-hypervisor-3.0.3-1-i386 Version: 3.0.3-0-1 Severity: normal -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, When you have a HVM domain running, if you try to boot a regular paravirtualized domain, dom0 (or maybe the hypervisor) crashes immediately (reboot). The opposite (trying to boot a HVM domain while a regular paravirtualized domain is running) crashes the system as well. I

Yes, like real Linux/ia64, it is not possible to run the same Xenlinux bits both on ski and on real hardware. A different configuration and build is required. The config difference is the same as it was with the privified xenlinux... I think you did that successfully before (with privified xenlinux) so give that config file a try and if it doesn''t work, let me know. BTW, I think I know

The virtualization manual doesn't seem to say; does one have to do anything to get the Centos 5.5 paravirtualization drivers installed? Or is it sufficient to specify a paravirtualized guest, and the Centos install will then detect that and load the right things? And, is there a way to check in the guest that the right drivers are loaded? What are they? -- David Dyer-Bennet, dd-b at

I have posted in http://vireso.blogspot.com my notes about installing Centos5 (from DVD image) into DomU on OpenSolaris Xen (xen-nv66-2007-06-24). Using OpenSolaris for Dom0 gives such advantage as zfs zvols for "phy" devices in DomUs, so zfs snapshot & zfs send gives you incredible fast and convenient full/incremental backup/restore of full DomUs.

Dear CentOS, I have recently upgraded several servers from CentOS4 to CentOS5 and I am noticing a strange change to the stat() call. I have written a very small program to test and show the behavior. I am calling stat() against a file which is exported from my NAS and mounted with 32k read/write sizes. [dougalb at centos4 tmp]$ cat my_stat.c #include <unistd.h> #include <stdio.h>
