Hi all, I am trying to test new xen packages from official centos repos. This centos 6.4 x86_64 host is my main virt platform at home (KVM based). My idea is to use kvm and xen in this same host (using init level 3 for kvm and init level 4 for xen), but when I try to install xen packages (using the procedure described in wiki), xen installs new kernel and tries to remove my kvm-kernel aware (remember, official kernel from centos repos). From my point of view, it is not admissible. Do I need to do another complete centos OS install to use xen packages?? Is not possible to use both kernels with only one OS install?? Thanks.

Can you post some more specific details about what the problem is and ideally, the yum transaction logs ? - KB -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc

We know this happens, and we may try to work on it in the future, but for now KVM and Xen on the same base machine is not supported. The kernel would do KVM though, just not all the packages will install if you are installing xen as well. -------------- next part -------------- A non-text attachment was scrubbed...

Thanks Johnny, I will do a second installation to test new xen repo ...
