Hello,
What is the best way to get the xen enabled CentOS 5.2 vmlinuz and initrd images for use as a guest domain (domU) on Ubuntu host domain (dom0).
Is there a site where these are available? I am hoping that I could use the vmlinuz from the latest kernel rpm, if I go that route, how could I generate the initrd image given that my host is Ubuntu?
These are for use with post install of domU, which is setup using xen-create-image.
Thanks

Look in images/xen/.

Are you sure I could use those? Are n't they used for installation and probably as a xen host?
Thanks

virt-install on a CentOS 5.2 system and transfer the image over to Ubuntu.

Please use something better.

Could I do it on any system or a system with similar architecture? Is it possible to generate the initrd using a live CD?

I have checked my profile and I had the name listed as A.A., I don't know where this is coming from. Yahoo is slapping it onto the mail message from some place. I need to figure it out and get rid of it
Thanks

Probably. You may want to have a look at the jailtime.org images. They should have a complete CentOS 5.2 or 5.1 image.

I did look at jailtime.org. Their image file seems to contain everything excepting for vmlinuz and initrd. You may need to generate 'initrd' image on the machine itself, but vmlinuz could have been packaged with the rest, but they didn't. I am sure there is a reason for it.
I tried to go thru a different route to accomplish the above. I tried to use instructions from: http://www.virtuatopia.com/index.php/Building_a_Xen_Guest_Root_Filesystem_us...
I was trying: "yum --installroot=/xen -y groupinstall Base" and I got the error: ================================================== (373/375): openldap-2.3.2 100% |=========================| 294 kB 00:05 (374/375): dhcdbd-2.2-1.e 100% |=========================| 61 kB 00:00 (375/375): python-2.4.3-2 100% |=========================| 5.9 MB 00:12 warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID e8562897 Importing GPG key 0xE8562897 "CentOS-5 Key (CentOS 5 Official Signing Key) centos-5-key@centos.org" from http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5 Traceback (most recent call last): File "/usr/bin/yum", line 29, in <module> yummain.user_main(sys.argv[1:], exit_code=True) File "/usr/share/yum-cli/yummain.py", line 236, in user_main errcode = main(args) File "/usr/share/yum-cli/yummain.py", line 188, in main base.doTransaction() File "/usr/share/yum-cli/cli.py", line 364, in doTransaction if self.gpgsigcheck(downloadpkgs) != 0: File "/usr/share/yum-cli/cli.py", line 464, in gpgsigcheck self.getKeyForPackage(po, lambda x, y, z: self.userconfirm()) File "/var/lib/python-support/python2.5/yum/__init__.py", line 2571, in getKeyForPackage misc.import_key_to_pubring(rawkey, po.repo.cachedir) File "/var/lib/python-support/python2.5/yum/misc.py", line 278, in import_key_to_pubring ctx = gpgme.Context() NameError: global name 'gpgme' is not defined ==================================================== I am using version 3.2.12-1.1.
Any suggestions on what could be causing the above. Is it possible to start from where it left off (ie it already downloaded the required packages)?
Thanks

Ah, well, could be so. I forgot about that. That's a dead end, then ;-)

Make it easier. Get the jailtime image. Mount it, chroot to it, install the xenU kernel, mkinitrd, boot with pygrub. Now that I'm reminded of that I know that it works, I did it with CentOS 4 jailtime images.
