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:

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

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

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. At the weekend I went into the office 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

Hi, I updated a server yesterday from "kernel 2.6.18-128.7.1.el5xen" to "kernel 2.6.18-164.el5xen" After rebooting, my message log is flooded every second or so with this error messages: Oct 6 14:52:20 xenserver1 kernel: EDAC MC0: UE row 0, channel-a= 0 channel-b= 1 labels "-": NON-FATAL recoverable (Branch=0 DRAM-Bank=0 Buffer ID = 0 RDWR=Read RAS=0 CAS=0

# ipsec verify ... If you encounter network related SElinux errors, especially when using KLIPS, try disabling SElinux ... Well, it is not running KLIPS but netkey, anyways I feel not comfortable about disabling selinux on a ipsec router. I am not sure how to handle possible probems in this case, too. If I decide not to disable selinux, and I run into problems, should I a) report it to redhat

Setup: RedHat/Centos/Sci. Linux 5 update 3, Dom0: kernel-xen-2.6.18-164.10.1.el5xen 64-bit (on Dell Poweredge 2950 dual quad-core). DomU: kernel-xen-2.6.18-164.10.1.el5xen 32-bit, 1 vcpu 6 domU''s per dom0. We have also seen the same problem with 2.6.18-164.9.1 and 2.6.18-164.6.1 kernels on this branch. Symptom: On 32-bit domU only (we have never seen 64-bit domU be affected), we observe

Hi, I'm having a linux box running with Centos 5.3 x86 (kernel 2.6.18-128.7.1.el5xen) which is freezing time to time and can't login neither trough console. The only thing what I can do, to pass the situation is to power off/on the pc. The pc is used only as a torrent server running with transmission 1.74. There are days when 400GB data traffic goes through the pc, and there

Hello everybody. I would like to do some kind of shaping inside an ipsec tunnel implemented by Openswan and linux 2.6.18.x with xfrm (no KLIPS): for example, to limit outbound smtp traffic inside the tunnel. Question: where should I attach the qdisc to? Eth0? I''m asking this, because tcpdump only see the ESP packet on the eth0 and not the ''clear'' packet. TIA This is my

Hi List, Is there easy way to get klips ipsec stack into centos 6? As it makes firewalling ipsec traffic much easier.. Eero

Greetings, I?m new to xen virtualization on CentOS, but I have been unable to find the answer to this problem I?m experiencing. My setup: AMD quad core (64bit), 8Gb ram. CentOS 5.3 dom0, CentOS 5.3 domU?s (paravirtualized). Dom0 is set up with two NIC?s, the built-in and a PCI card, and I set up xen bridging on both interfaces. My domU?s seem to boot up fine, run fine, and

On the subject of kernel updates: I had my install kernel (2.6.18-8.el5xen) and 2.6.18-8.1.8.el5xen on the box. I was unable to originally boot the update (8.1.8xen) because of the 3ware driver issues (I needed to use a driver floppy at install time). I jumped through some hoops (which I am struggling to understand) with weak-updates to get the 2.6.18-8.1.8 kernel to see my raid devices, which

xen-3.0.3-94.el5_4.2 2.6.18-164.6.1.el5xen RHEL5.4 x86_64 I''ve got a dom0 that does nothing but have a DomU created. The DomU gets plenty of load. Over time, the dom0''s ipconntrack table fills up but not the DomU. Once it gets full I can restart iptables and it''s fine. The strange thing is this only happens on hosts I have provided (hardware and hosting) from one

Hi all, I am in a bit of a fix here, I have several Guests paravirtualized running on a Dom0 that is currently running the 2.6.18-92.1.22.el5xen Kernel. All my guests (administered by different people) have subsequently been updated to later versions of the kernel (namely 2.6.18-164.el5xen or 2.6.18-128.4.1.el5xen). Ones that are still running are using the Kernel 2.6.18-128.4.1.el5xen while

I installed XEN. my kernel is 2.6.18-1.2747.el5xen I downloaded ipw3945-linux-1.2.0 This told me do download ieee80211-1.2.16 So when I try to compile ieee80211 it tells me find: /lib/modules/2.6.18-1.2747.el5xen/build/: No such file or directory egrep: /lib/modules/2.6.18-1.2747.el5xen/build//.config:

Hi all, I just installed centos 5.4 xen-kernel on intel core i5 machine as dom0. After some hours of syncing a raid10 array (8 sata disk) I noticed a steadily increasing loadavg. I think without reasonable i/o wait or cpu utilization the loadavg on this system should be very lower. If this loadavg is normal I would be greatful if somone could explain why. The screenshots below show that there is
