User-agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2.22) Gecko/20110906 Fedora/3.1.14-1.fc14 Thunderbird/3.1.14


Compiled 3.1.0-rc3+ from source (see attached config file) and updated the host(fc14) kernel ;
So host is now running 3.1.0-rc3+

Now I also want to try to boot FC14 guest with this updated kernel , like this -

./qemu-kvm-virtfs -drive file=/home/onkar/bin/v9fs-guest.img,if=virtio -m 1024 -smp 4 -net nic,macaddr=54:52:00:46:26:84,model=virtio -net tap,script=./qemu-ifup,ifname=vnet1 --enable-kvm -vnc :10 -kernel /boot/vmlinuz-3.1.0-rc3p -initrd /boot/initrd-3.1.0-rc3p.img -append 'root=UUID=97e4bdfa-c88b-4e1f-8609-10f76d6a35fa' -monitor stdio

-append 'root=UUID=97e4bdfa-c88b-4e1f-8609-10f76d6a35fa'
has come from guest grub/menu.lst file generated during installation , which looks like this :

=====================================================================
title Fedora (2.6.35.6-45.fc14.x86_64)
    root (hd0,0)
kernel /boot/vmlinuz-2.6.35.6-45.fc14.x86_64 ro root=UUID=97e4bdfa-c88b-4e1f-8609-10f76d6a35fa rd_NO_LUKS rd_NO_LVM rd_NO_MD rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYTABLE=us rhgb quiet
    initrd /boot/initramfs-2.6.35.6-45.fc14.x86_64.img
=====================================================================

But, the guest freezes with error (see screen shot attached) when tried to run
with the updated kernel ..

Trying to debug this for long time now , no clue on what's going on ..

Please help. Has anyone noticed something like this before ?
