Problems saving Domain with "xm save"
by Ignacio Verona 26 Apr '06

26 Apr '06

Hi, I'm trying to make a backup image of one of my guest OS, using the command "xm save" as said in the Wiki and in the Xen documentation, but the execution of the command is as follows: [root@aguilaM ~]# xm save aguilaz /xenM/backup/aguilaz-backup2.chk Error: /usr/lib/xen/bin/xc_save 10 17 1 0 0 0 failed Is this a known bug? I haven't found anything related to that. Thanks, Ignacio

Is there any reason why this module isn't built into the kernel by default, so folks setting up 2.4-based guest operating systems (e.g, RHEL3) can avoid building a custom kernel? Is there an easier way that I have overlooked? Thanks, Ryan

using centos 4.3 ad guest
by Kim Gabrielsen 24 Apr '06

24 Apr '06

Hi, I have successfully installed Xen with fedora core 5 and i have installed a guest system running fedora core 5. The guest is running without problems. I'm now trying to install a guest based on centos 4.3. i create the guest system using xenguest-install.py and the process is like this: What is the name of your virtual machine? centos How much RAM should be allocated (in megabytes)? 256 What would you like to use as the disk (path)? /xen/centos What is the install location? http://mirror.fysik.dtu.dk/linux/centos/4.3/os/i386/ Invalid URL location given but why does it give me an 'Invalid URL location given' error message? I can see the URL in my browser and i can see the centos install tree. i have tried with nfs also using my local centos install tree using: nfs:miraculix:/usr/public/distributions/centos43_i386 but it fails. if i use nfs:miraculix:/usr/public/distributions/fedora5_i386 it woks perfectly and was the install tree i used for creating my first guest system. im using the latest xen version. hope someone can help me cause i'm pretty much stuck here and i don't see much point in using xen if i can only run guest systems based on fedora 5. br kim gabrielsen

Running FC4 as guest in FC5 Xen
by Ignacio Verona 24 Apr '06

24 Apr '06

Hi, this is my first post to the list, and I've been reading it for a while. Although there are some posts regarding how to instal FC4 as a guest in FC5, I'm not able to get it running. FC5 guest is ok, but how do I install an FC4? I've followed all the steps for the FC4 QuickStart, I don't know which kernel should I load. First, if using the kernel installed with my FC5 installation (vmlinuz-2.6.16-1.2096_FC5xen0) the kernel boots, but then it hangs because it doesn't find the root fs (sda1). I've tried to do a chroot into my fc4 minimum installation (under /mnt) and install the vmlinuz-2.6.13-1.1532_FC4xenU, copy it to the host machine and put it into the configuration, but then, when booting the guest I get a message saying that the argument is invalid. Looking the logs, y see this: ERROR: Will only load images built for Xen v3.0 ERROR: Actually saw: 'GUEST_OS=linux,GUEST_VER=2.6,XEN_VER=3.0,VIRT_BASE=0xC0000000,PAE=no,LOADER=generic' ERROR: Error constructing guest OS So, what are the exact steps (or the steps which differ from the FC4 XenQuickStart) that should I take in order to get FC4 running under FC5? Thanks a lot in advance, Ignacio.

PAE and FC5 Xen on 32-bit system
by Matthias Bayer 24 Apr '06

24 Apr '06

Hi, i have a 32-bit FC5 system running with default xen from FC5 (kernel-xen0-2.6.16-1.2096_FC5 & xen-3.0.1-4). my system has 4GB of memory but xm info only shows 3584MB available. i know i need PAE support but the question is if there is a PAE enabled kernel from FC5 32-bit xen systems available already or if i can turn on PAE support easily somehow. for me it's important to stay 'supported' and use only 'officialy availbale' packages. if there is no such a PAE enabled version available can somebody explain what exactly needs to be done to turn PAE support on, i searched the web and found lots of different instructions but i am not sure which one is the 'correct' one ? thanks for any help ! regards, Matthias _______________________________________________________________ SMS schreiben mit WEB.DE FreeMail - einfach, schnell und kostenguenstig.

MAC to IP, iptables security for xen guests?
by Jon Stone 23 Apr '06

23 Apr '06

With each xen guest having its own virtual MAC address, is it possible at the dom0 level to set iptable rulesets which act as ip based access control lists per guest? Essentially the concept would be to limit the IP address per Xen guest, at the host level, so that a guest domain would not be able to assign itself the IP address of dom0 and create IP conflicts. Thanks

Newbie help
by Brandon DeYoung 21 Apr '06

21 Apr '06

Hi All, I'm trying to get RHEL 3 to run as a guest domain and am not sure where to start. I have installed FC5 and am able to get FC5 guest domains running using the niffty tools developed by the Fedora folks. I can't find a howto anywhere on running RHEL 3 (or 4) as a guest domain. I'm planning to use these to do some integration testing, so would like to get these guests as close to RHEL 3 as possible i.e. using a 2.4 kernel, etc.. Any advise is helpful, if someone has found or written a howto, that is even better. Thanks in advance, ~Brandon
