how to build a customized xen kernel for guest OS

by pradeep ratnala

Hi I successfully installed FC6 with xen ....I could also start FC6 guest domains using virt-install... Everything is ok till now...... But I need to change the kernel of the guest domain with my own kernel (for project purpose).......So I started compiling a new kernel (2.6.19) in the guest domain..... I could compile it and even add a grub entry but couldnt boot the guest domain with this new kernel....The problem is that the new kernel I built is not xen aware and hence it is not supporting paravirtualization............ so can anyone guide me how to develop xen aware kernels........... thanks in advance Pradeep

Hi! I have a problem to start this card. I have installed the driver from: http://sourceforge.net/projects/atl1 The install process looks fine. But when i want to start my NIC: > [root@localhost network-scripts]# /etc/init.d/network start eth0 > Loopback-Schnittstelle hochfahren: [ OK ] > Schnittstelle eth0 hochfahren: > IP-Informationen werden für eth0 bestimmt..../network-functions: line 308: > 30827 Getötet ip link set dev $1 up >/dev/null 2>&1 My Kernel version: 2.6.20-1.2933.fc6xen Under the normal kernel the NIC works.

- Question on live migration

by Davidson Paulo

Hi, I'm going to make a live migration of some Xen guests from a machine to another. At the moment I'm preparing both systems, syncing software versions, while I read some documentation about the live migration process. The process looks simple, but I'm still have only one question. Let me explain: I have a guest on my Xen host 1 that have 3 virtual partitions that are mapped to 3 logical volumes of the host, as follows: Guest virtual partition Guest mount point Host physical partition /dev/sda1 / /dev/xenvg/apache-root /dev/sda2 swap /dev/xenvg/apache-swap /dev/sda3 /var /dev/xenvg/apache-var On the Xen host 2, I created the same physical partitions existing on Xen host 1, with same name and locations. So, at the moment I think my next steps are: 1. Copy the config file for the guest from Xen host 1 to Xen host 2 2. Execute on Xen host 1: # xm migrate --live guest host2 Is that right or is something missing? Note.: I read many docs, and all they say that I need to make image files available on both Xen hosts. But I'm not using image files, but logical volumes... Thanks, Davidson Paulo

- kernel-xen, kernel-xen0 and kernel-xenU

by Davidson Paulo

Hi, I'm using Xen on a Fedora Core 5, with kernel-xen0 on host and kernel-xenU on guests. Friday last I've installed kernel-xen both in host and guests, and guests stopped to work. Now, I'm reinstalling kernel-xen0 on host and kernel-xenU on guest... I know kernel-xen0 is built to run on the Xen host, and kernel-xenU to run on guests. But I can't understand kernel-xen... when use it? Thanks, Davidson Paulo

dummy network interface laptop configuration problem

by Deependra Singh Shekhawat

Hello guys, I am using Redhat Enterprise Linux 5 with Xen. Now I have a laptop on which RHEL5 is installed. I read the docs related to Xen on redhat's website where in the troubleshooting section they say to create a dummy0 network interface and bridge xenbr0 to dummy0 and finally NAT'ing dummy0 so that it can access the public net. Well I tried that article and I created a dummy0 interface as told in there and also bridged dummy0 to xenbr0 in /etc/xen/xend-config.sxp but I am getting problem in configuring NAT'ing (so that I can access the public network from within the virtual machine). I am using the script given here: https://www.redhat.com/docs/manuals/enterprise/RHEL-5-manual/Virtualizati... When I run the script I get these two errors: ./S99XenLaptopNAT: line 21: unexpected EOF while looking for matching `"' ./S99XenLaptopNAT: line 24: syntax error: unexpected end of file Regards Deependra -- Enjoy Life !

Guests from other distros

by John Summerfield

When available, I intend to install Centos 5 on my laptop. I wish to be able to create guests from other distros (notably Debian), preferably running their native installer. So far, it seems that everyone (RH/Fedora, Debian/Ubuntu and SUSE, I've not looked further) has different, incompatible tools. Even copying a VM from one distro to another isn't as simple as one might expect. Are there any useful docs for me to read? -- Cheers John -- spambait 1aaaaaaa(a)coco.merseine.nu Z1aaaaaaa(a)coco.merseine.nu Please do not reply off-list
