Well, since this caused lot's of questions, here is my setup: Main host: Debian squeeze, kernel 2.6.28 or .29 (doesn't matter), qemu-system-x86_64 version 0.10.2 KVM kernel run inside qemu: e3dbe3f408a46a045012f1882e9f62b27b8a616c from Avi's tree (KVM: x86 emulator: fix call near emulation) + these patches. I have to boot the kernels (both this kernel and 2.6.26 from debian) with noapic to w/around APIC problems (I dunno if it's qemu or bochsbios problem). system inside qemu: 64-bit debian lenny KVM userspace: debian 84+dfsg-2 inside kvm I run 32-bit debian lenny with plain debian 2.6.26 kernel. -- With best wishes Dmitry
