KVM-86 not exposing 64 bits CPU anymore, NICE
Hi, I'm quite pissed off. I just upgraded to kvm-86 on a host that has worked nicely on kvm-78 for quite some time. But since I was fearing the qcow2 corruption issues, I wanted to upgrade kvm-86. After testing the performance, I decided to switch. How stupid that was. That was really putting too much trust in KVM. Now I can't have 64 bits CPUs on my guests. My host is running a 2.6.27.7 kernel, and is x86_64 enabled. Until the upgrade, guests were running x86_64 fine. Now, it says long mode can't be used or something like that, and I can only have 32 bits guests. 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
