DomU second /29 on eth0
by Tracy Phillips 03 Nov '09

03 Nov '09

Hi, I have a question that relates to adding additional IP's to a Xen guest. Do I need to do anything at the Dom0 level to add a /29 to a DomU that has an IP from Dom0's /29? I certainly hope that made sense. Thanks in advance for your help. Tracy Phillips

SATA vs RAID5 vs VMware
by Philip Gwyn 03 Nov '09

03 Nov '09

Hello, I have strange behaviour on a server that I can't get a handle on. I have a reasonably powerful server running VMware server 1.0.4-56528. It has a RAID5 build with mdadm on 5 SATA drives. Masses of ram and 2 XEON CPUs. But it stutters. Example : fire up vi, press and keep finger on i. After filling 2-3 lines, the display is stopped for 2-12 seconds. Then they continue. This happens even on the host OS, at the console. Host system running CentOS 5.2 x86-64: CPU : 2x Xeon E5430 @ 2.66GHz RAM : 24GB Mobo : DSBV-DX HD : 5 x SATA ST3750330AS 750GB in RAID5 There are 5 VMs, detailed at http://www.awale.qc.ca/vmware/stj1.txt to make this mail shorter. Seems to me this system should be more then adequate to handle the load. This is what vmstat on the host looks like when the server is "unhappy" : http://www.awale.qc.ca/vmware/vmstat.txt Spending a lot of time in 'wa', but 'bo' and 'bi' are miniscule. The problem seems like a disk problem. I grow to suspect that SATA isn't ready for the big time. I also grow to dislike RAID5. Questions : - Anyone have a clue or other on how to track down my bottle neck? - SATA NCQ is limited to 15 queue depth. Is this per-SATA-port or per-SATA-chip? Or does this question make no sense? - I realise there are more recent versions of CentOS out. Are there specific items in the changelogs that would affect my problem? Thank you for any help, -Philip

Redhat 7.3 as Centos 5 domU
by Mindaugas Riauba 02 Nov '09

02 Nov '09

Hello, What is the simpliest way to run Redhat 7.3 server as CentOS 5 domU? I see that Xen emulates Intel PIIX ATA controller for HVM domUs but latest kernel of Redhat 7.3 (2.4.20-20.7smp) has no ata_piix kernel module yet. Is it possible to download it somewhere or there is another way? :) Regards, Mindaugas

img partitioning & swap
by Adam 01 Nov '09

01 Nov '09

Hello everyone, I am moving a 2 node cluster from XenServer + iSCSI with lvm to CentOS 5.4+Xen on NFS using .img files. What do you guys use for your partition scheme for .img files? I see examples where people create another .img to use it as swap. I was gonna put lvm inside the .img and create separate filesystems in logical volumes(/var, /home, /opt, /tmp and swap). -Adam
