Package: qemu-kvm
Version: 0.11.1+dfsg-1
Severity: important

I'm trying to install virtual machines with FAI, and for this purpose have installed a full FAI infrastructure (using dnsmasq) on my host system, listening on br0. Currently I'm booting 2.6.31-grml64, but I have tried this with standard Lenny kernels as well, both 32- and 64-bit.

I create the virtual machine with:

virt-install -n test -r 256 --vcpus=1 --os-variant=debianlenny --pxe --disk path=/dev/vg2/test_root --disk path=/dev/vg2/test_swap -w bridge=br0,mac=52:54:00:25:00:00,model=virtio --vnc

The PXE boot works after a few tries (the boot ROM always claims to not get an answer the first few times) and then the kernel boots. Once the initrd proclaims "Begin: Mounting root filesystem ..." I get the following kernel messages:

NET: Registered protocol family 17
Kernel panic - not syncing: Attempted to kill init!
Pid: 1, comm: init Not tainted 2.6.31-grml63 #1
Call Trace:
 [<ffffffff81529290>] panic+0xc6/0x17c

 [<ffffffff81060047>] sys_exit_group+0x2a/0x42
 [<ffffffff810120b2>] system_call_fastpath+0x16/0x1b

I have quite a bit of experience with FAI and I have never seen this problem on real hardware. On my host system I am running squeeze with 2.6.32-trunk-amd64 and a triple core AMD Phenom 8650.

In Lenny I was able to get FAI working on KVM using VDE, however, that doesn't play nicely with libvirt so I would really like to get it working like this.

If you need any further information or e.g. my complete FAI configuruation, nfsroot, kernel or initrd, please do not hesitate to contact me.

Regards,
Michael
