same problem? If you need to do another test, please don't hesitate to ask me. As I noted earlier, trying to migrate from Defiant (Debian GNU/Linux 5.0.8 with Linux 2.6.32-15~bpo50+1 and qemu-kvm 0.12.5+dfsg-3~bpo50+2) to SS01, this problem does not occur. Both installation are 32-bit, but the kernel in SS01 is amd64 and the kernel in Defiant is i686. Ie both are 32bit userspace with the difference that ss01 has a 64-bit kernel. The problem is there? Because versions of Linux and qemu-kvm look the same. Thanks for your reply.
