I've been using KVM for a few years now. I've had little trouble with it. But
now it's got me treed. I cannot get a KVM-enabled Linux 3.2.27 kernel to boot
in qemu-kvm unless I specify '-no-kvm'. I've used a similarly-built and -
configured 2.6.35 kernel without trouble.
The console shows
Probing EDD (edd=off to disable)... ok
Decompressing Linux... Parsing ELF... done.
Booting the kernel.
And there it hangs, the kvm program at 100% CPU usage.
This is on Debian Squeeze, either using Debian's kvm package or using a
freshly built kvm 1.1.1. The kernel does boot using qemu or booting on real
hardware. And I've no trouble booting Linux 2.6.35.
Clearly I've missed something, but I've no idea what that might be. Any ideas?
Thanks,
N

I'm also on squeeze, with qemu-kvm_1.1.0+dfsg-3 compiled by myself.
For me, booting 3.2.27 in a VM guest works just fine:
$ cat /proc/version
Linux version 3.2.27 (wg@sputnik) (gcc version 4.3.2 (Debian 4.3.2-1.1) ) #1 SMP Mon Aug 13 11:55:10 CEST 2012
$ zgrep KVM /proc/config.gz
CONFIG_HAVE_KVM=y
CONFIG_HAVE_KVM_IRQCHIP=y
CONFIG_HAVE_KVM_EVENTFD=y
CONFIG_KVM_APIC_ARCHITECTURE=y
CONFIG_KVM_MMIO=y
CONFIG_KVM_ASYNC_PF=y
CONFIG_KVM=m
CONFIG_KVM_INTEL=m
CONFIG_KVM_AMD=m
I boot from network, and I just successfully insmod'ed the kvm
module. Inserting kvm-intel fails however (to be expected I guess).
No hangs or crashes.
Can you please post your complete qemu command and host kernel
version?
Regards,
Wolfram.

You missed to provide the qemu/kvm command line you're using.
As for the sympthoms, you may be hitting http://bugs.debian.org/680719
but it is difficult to say without much more details.

Using Squebian's 2.6.32-5-686-bigmem, the 3.[024] kernels I built (with KVM)
don't boot.
Trying Squebian's 2.6.32-5-amd64. ... 3.0.41 and 3.4.9 now boot
using either Squebian's kvm or qemu-kvm v1.1.1.
Trying Squebian's 2.6.32-5-686. ... And the 3.0 and 3.4 kernels boot using
either version of qemu-kvm.
Does that help narrow the problem?

No. Please provide the guest's serial log. Also run 'top' and
'kvm_stat' on the host to see what the guest is doing.

I *may* be using a newer BIOS; IIRC (it's been a long while) the stock BIOS
would give me continual errors (making the VM real slllooooowwwww).
Also tried with the latest (via /usr/local/bin/qemu-system-i386, command is
otherwise the same):

3.0.41 and 3.4.9 also hang. I'll start working my way back to 2.6.35 until I
find a kernel that boots.
