Hello,

  I'm running for servers with RHEL 5.1 XEN on it. On each of them, I'm running
2 big Para-Virt RHEL 5.1 also.

  I would like to know if someday, RedHat decide to upgrade the kernel and make
a RHEL 5.2 for example. If I upgrade DomU to 5.2 with a new Xen Kernel, it will
broke all my Para-Virt RHEL 5.1 machines ?

  If I do the opposite, keep RHEL 5.1 XEN on DomU and upgrade the Xen kernel
inside a Para-Virt machine, is my machine will also broken ?

  In clear, how are XEN "relationships" between guest & host ? Are they easily
breakable? What are the common rules in that area?


  thanks by advance,


   LMJ
