I have been following the tutorial referenced here. http://www.howtoforge.com/create-centos5.2-domu-on-ubuntu-hardy-dom0 Now there are lots of typos and errors in the tutorial, but I managed to overcome them. Upon creating the CentOS DomU, I do get a login prompt and can login. The first issue I had was that I couldn't get any updates or install packages. I thought it was a DNS issue. But after fixing that, I noticed I couldn't even ping. Typing ifconfig at the command prompt, I noticed that eth0 has a MAC address, but no IP. I did follow the tutorial on specifying the IP. I also tried specifying it in the Xen config file for the DomU. Regardless of which method I try, I get an error message upon starting the DomU that says another host already has claimed this IP address. I know for a fact that is not the case. I have changed the IP address too and no matter what I change it to, I get the same error message. Any ideas of where to look next?
I haven't tried that tutorial, but I'd use xen-tools for creating guests. They also support creating CentOS guests.
I tried your suggestion tonight of using xen-tools. First, I looked under /usr/lib/xen-tools and saw two CentOS related directories: centos-4.d and centos-5.d. So I assumed that when creating the DomU using xen-tools, I would use the parameter: Code: --dist=centos-5 However, the installation failed. Below is the sanitized result of the log file. Code: General Information -------------------- Hostname : centos-5.example.com Distribution : centos-5 Partitions : swap 256Mb (swap) / 10Gb (ext3) Image type : sparse Memory size : 256Mb Kernel path : /boot/vmlinuz-2.6.24-23-xen Initrd path : /boot/initrd.img-2.6.24-23-xen Networking Information ---------------------- IP Address 1 : 192.168.100.103 [MAC: 00:16:3E:XX:XX:XX] Netmask : 255.255.255.0 Broadcast : 192.168.100.255 Gateway : 192.168.100.1 Creating partition image: /home/xen/domains/centos-5.example.com/swap.img 0+0 records in 0+0 records out 0 bytes (0 B) copied, 4.1828e-05 s, 0.0 kB/s Done Creating swap on /home/xen/domains/centos-5.example.com/swap.img Setting up swapspace version 1, size = 268431 kB no label, UUID=76fa5bc5-1262-4ec1-975e-f1e735698c1a Done Creating partition image: /home/xen/domains/centos-5.example.com/disk.img 0+0 records in 0+0 records out 0 bytes (0 B) copied, 4.521e-05 s, 0.0 kB/s Done Creating ext3 filesystem on /home/xen/domains/centos-5.example.com/disk.img mke2fs 1.40.8 (13-Mar-2008) Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) 655360 inodes, 2621440 blocks 131072 blocks (5.00%) reserved for the super user First data block=0 Maximum filesystem blocks=2684354560 80 block groups 32768 blocks per group, 32768 fragments per group 8192 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632 Writing inode tables: done Creating journal (32768 blocks): done Writing superblocks and filesystem accounting information: done This filesystem will be automatically checked every 27 mounts or 180 days, whichever comes first.

The system is missing the common file: /bin/ls Done System installation failed. Aborting I get a similar error when trying a CentOS 4 DomU as well.
So I changed the --install-method parameter to be rpmstrap instead of the default debootstrap. Now I receive the following error: Code: Installation method: rpmstrap The following required binary for the installation was not found /usr/bin/rpmstrap Done System installation failed. Aborting I googled around and found many references to rpmstrap being broken in Gutsy. I am running the Hardy (8.04 LTS) server version. I also did an apt-cache search for the rpmpackage, but nothing was found using the standard repositories. On the Ubuntu site, I could only find the package mentioned in the Gutsy and Gutsy-updates listings.
If rpmstrap doesn't work, you can also use rinse. There's a rinse package for Hardy. Of course, you must configure xen-tools to use rinse instead of rpmstrap.
So I installed rinse and the dependency package rpm. The xen-create-image command appeared to work great without any errors. However, when starting the DomU using the -c parameter to go into the console, a prompt appears requiring me to log in for Maintenance. I don't know the default password. When the xen-create-image was running, it stated that there is no passwd command in the centos-5 package and so the password was not changed when the image was created. Any suggestions?
Here is a snippet of the xen-tools log file for this DomU.

Sorry Falko, but I don't know how to do what you are asking. I only have about a year on Linux, all with Ubuntu. There are some things I can do and have been able to figure out on my own, but I don't know where to start with your request. Are you asking me to mount the root LVM partition of the CentOS DomU somewhere on Dom0?
Yes, like this: Code: mount /dev/vg0/vm1 /mnt chroot /mnt passwd (Replace /dev/vg0/vm1 with the correct volume.)
Sorry, but this is what I get when I chroot into the LV for the CentOS DomU and issue the passwd command: Code: bash-3.2# passwd bash: passwd: command not found
Here is the output of yum search passwd when the DomU is mounted and chroot. Code: bash-3.2# yum search passwd Traceback (most recent call last): File "/usr/bin/yum", line 4, in ? import yum File "/usr/lib/python2.4/site-packages/yum/__init__.py", line 37, in ? import rpmsack File "/usr/lib/python2.4/site-packages/yum/rpmsack.py", line 24, in ? from packages import YumInstalledPackage File "/usr/lib/python2.4/site-packages/yum/packages.py", line 31, in ? import rpmUtils.arch File "/usr/lib/python2.4/site-packages/rpmUtils/arch.py", line 273, in ? canonArch = getCanonArch() File "/usr/lib/python2.4/site-packages/rpmUtils/arch.py", line 269, in getCanonArch return getCanonX86_64Arch(arch) File "/usr/lib/python2.4/site-packages/rpmUtils/arch.py", line 232, in getCanonX86_64Arch f = open("/proc/cpuinfo", "r") IOError: [Errno 2] No such file or directory: '/proc/cpuinfo' It looks like an error with /proc/cpuinfo, but I don't know how to proceed. Up until now, I have been an apt-get and not a yum guy. This is really my first exposure to CentOS and it is through my Xen machine.
Hm... I've never tried to install CentOS with xen-create-image. Seems as if there are still a few bugs. Have you tried to install the latest xen-tools package directly from the xen-tools web site? Maybe it works with that version.
I haven't tried that yet, but I could. I guess I could back up a step here and explain why I am trying to install CentOS. I was really hoping to install HyperVM on a DomU to test the management of my Xen virtual machines. In my network, all servers are Linux servers and they run headless. Therefore, it appears that others I have tried such as Virt-Manager required some kind of graphic desktop environment to be enabled on the server. The client machines on the network are all Windows XP machines. Most of the server management is done from these Windows machines through SSH. Has anyone had any luck in installing a Xen management console on a Windows machine? One option I thought about was using a live CD or USB key an effectively run a Linux environment on the Windows machine temporarily to manage Xen. Thoughts?
The tools that I know are all Linux-based... (that doesn't mean there isn't a cool Windows tool out there).
