You should be able to run with no problems immediately after upgrading. If it doesn't work, please report how, what guest you are using and what is your host cpu version. There may be a problem if kvm changes its reported cpuid string and the guest is sensitive to that, but otherwise it should just work. -- Do not meddle in the internals of kernels, for they are subtle and quick to panic. ------------------------------------------------------------------------- SF.Net email is sponsored by: Check out the new SourceForge.net Marketplace.
