No problem on Fedora 12 as well. >=20 >=20 > Am I the only one to see this issue? >=20 The oldest kernels I've running here are 2.6.27. They all run kvm-kmod, and they are all happy (mostly). Are you using the KVM support 2.6.26 provided or are you on some recent kvm-kmod? The latter is highly recommended for tons of reasons.
