Did u get a chance to put up your new version of the nested KVM patch ? I am on KVM-70... can u tell me in bit more details on how I can go about getting your patches and Joerg's patch applied. -- What versions of KVM are these patches expected to work with ? -- Any sequencing or they are non-overlapping. -- Do I need to upgrade to some later version of KVM ? -- Are these patches already part of KVM-78 ?
