(in particular we have a machine with 2.6.24) Unfortunately the type of problem was not mentioned in the posts I could find. Is that a performance problem, a stability problem, or a data corruption problem... ? And I would also like to know if the "problem" can be worked around by installing a new kvm-kmod like 2.6.36.2 or we really need to upgrade the whole kernel to get rid of it. (I was thinking at installing a new qemu-kvm like the 0.12.5 on that) Thank you in advance
