Hello, I attempted to upgrade to Xen 4.1 from a stock centos 5.6 xen and kernel. Xend starts, but none of my DomU machines are listed. I googled quite a bit trying to find upgrade notes. The only thing I saw in the release notes was that I had to manually configure the bridges. The end result I''m after is to create a Ubuntu 11.4 DomU. Is this possible? If so, what version of xen should I shoot for? Performance is not a big issue. This is for a lightly loaded mail and web server. I''m happy to stick with the stock CentOS kernel. Thanks, Andy _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I had come across those. I had set the networking as described.

I had to switch to another box; one that is not running my mail server in a VM :) Why did I think this was going to be easy... The other box, also running CentOS 5.6, will not boot with xen 4.1.

Re: [Xen-users] centos 5.6 upgrade to 4.1 - no DomUs listed
Andy, had the same nightmare problem, stopped me for days, read and follow the networking section in this link, it is not using the Xen scripts to create the bridge at all, just pure os networking, check it out: http://wiki.virtastic.com/display/howto/Xen+3.4.3+on+CentOS+5.5+--+Tutorial ps - You most likely will not need the vlan .4094 but if you put it in it won''t hurt anything. Later if you run into a vlan requirement you will know how to deal with it.

Re: [Xen-users] centos 5.6 upgrade to 4.1 - no DomUs listed
People! Someone who is using the Xen scripts for the network bridge in Xen version 3.4.3 or later might want to write up how to do it correctly as it is not clear from anything I have seen so far. Thanks! I would do it but I am not using them to get my bridging done any longer.

Re: [Xen-users] centos 5.6 upgrade to 4.1 - no DomUs listed
Andy, looks like your image is not bootable, I have run into that, did not try to fix one, however, did some some posts related if you search. Since then I have created bootable images and have not had a problem loading them. If all else fails create a new bootable image (using remote/network install or kickstart or however) then mount the image, copy the data, and copy it to the bootable VM.

I updated libvirt to 0.9.1 from the default CentOS 5.6 one. libvirtd fails a test during the build, The attached trivial patch removes the failing test. The test fails because of CentOS using an old version of libxml2. I rebuilt with: rpmbuild -bb --define=''rhel 5'' libvirt.spec I''ve got a Ubuntu 10.04 guest running on CentOS now.

Re: [Xen-users] centos 5.6 upgrade to 4.1 - no DomUs listed
Andy, Thank you for feedback to the list, good for searches! It is interesting and strange that that worked. I am running CentOS 5.6 with the gitco Xen 4.1 and the libvirt is stock (not in gitco either): libvirt-0.8.2-15.el5_6.4 I just tested a ubuntu 10.04 image and it booted just fine, not sure why. I am also not sure about "the build", are you building everything from SRPMS?
