Re: KVM-86 not exposing 64 bits CPU anymore, NICE

Looks really like the bug explained here: http://www.mail-archive.com/kvm@vger.kernel.org/msg09431.html If I use -no-kvm, it works, but obviously, I want to be able to have kvm support enabled. Now, I really am happy about this upgrade, and I'm gonna have to roll it back. I really would appreciate some help on this.. Gilles Hi Gilles, What are you saying is very strange, because KVM-Autotest has passed all tests for KVM-86 release, and I can say that 64-bit guests work here. (both Intel AMD, on RHEL 5.3/x64) -Alexey -- To unsubscribe from this list: send the line unsubscribe kvm in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
