similar to: Xen fails with garbled boot screen - incompatible hardware?

Hi everyone Ok this is really strange. I''ve been messing around with Xen for the past few weeks on a 32bit test machine and CentOS 5.4 and it''s been working fine. Today I went into the office on a Sunday to install Xen on our server but I had a major problem. The server is a home-build with a Tyan s5211 motherboard with an Intel i3210w chipset CentOS 5.4 64bit installed and

I am currently using a Dell PowerEdge server R610 with Xen 4.0 installed and the 2.6.31.13 pvops kernel. I am accessing the server console using the iDRAC KVM feature of the dell management console. Does anyone know how to configure the console option in the grub menu so that all the boot messages can be seen on the mgmt console? Currently I can view only the Xen bootup messages if I dont specify

First let me say that I'm not a sysadmin, but am simply wearing that hat this week so please excuse my ignorance. I need to temporarily move some virtual servers from a CentOS-KVM platform to a CentOS-XEN platform while I do some upgrades to the CentOS box. I've created a local LV, and used DD and SCP to transfer the block device from the VKM machine to the XEN machine. For quite a

Hi all, Recently I build XEN 4.1 (from the xen.org) on centIOS 5.5 (kernel 2.6.38.4). After changing the grub file and rebooting the machine, I am continuously getting out of memory error.

I am having an issue with Megacli when adding or removing virtual disks. I will post a link to fpaste that has the issue shown. In brief whenever i add, or remove, a virtual disk via MegaCli the attempt succeeds and the adapter is configured but the OS remounts dm-0 in read only. dm-0 is my root lv. This issue does not happen if i boot into the default, non Xen, CentOS kernel. On stock

HI, We've started to see several issues with the Xen releases. Going back to basics I've used this guide https://wiki.centos.org/HowTos/Xen/Xen4QuickStart Once the install process is complete the grub.conf looks like this: default=0 timeout=5 splashimage=(hd0,0)/boot/grub/splash.xpm.gz hiddenmenu title CentOS (3.18.21-17.el6.x86_64) root (hd0,0) kernel /boot/xen.gz

Good morning, I need to use pciback.hide to hide a pci card because I want to pci passthrough that card to a domU. My hardware neither supports Intel-Vt-d nor AMD's IOMMU. Unfortunately this doesn't seem to work in Centos 54 anymore. I guess it doesn't work because it is not compiled into the kernel, but as a module. I got the following error in dmesg and the pci device is still

Hello..I am not very proficient in Linux kernel stuffs although I know my basics. I have a question and all suggestions/solutions will be highly appreciated... I got to know that RHEL 5 has inbuilt Xen Support...So I tried to install a RHEL 5.0 Server on my P4 machine. On top of it I tried to install Xen specific RPMs and some other RPMs needed by Xen. The additinal RPMs added after base

Does anyone have a standard install of CentOS virtualization grub.conf working in a proven state with the FALLBACK option? If so, can you post your grub.conf? I mistakenly updated to 5.5 and am concerned about nvidia driver comments in the release notes. I did not have protectbase configured on this machine. It is a remote device that will reboot.

Hello List, I am testing a XCP1 CentOS 5 paravirt vm with CloudLinux. http://cloudlinux.com/ CloudLinux is a great product for shared hosting and I was evaluation same on a paravirt guest.

Hi all, I have an odd problem, for which I couldn't find any suggestions on google.

Hi there, After updating a server from CentOS 5.3 to 5.4 my Xen pci-passthru setup has some troubles. The server has two NICs, one used by dom0 and the other assigned to a domU and one SCSI controler assigned to another domU. It has been working fine since CentOS 5.1, when I did the initial setup. After upgrading to 5.4, I get this error when starting the domU with one of the NICs assigned:
