Hi, all.
I want to study kernel, so I tried booting my custom compiled kernel on qemu with '-kernel' and '-initrd' option.
First, I installed ubuntu 10.10 with cdrom, no LVM. $ qemu disk.img -cdrom ubuntu-10.10-server-i386.iso -vnc :1
After installation, I tried booting my custom compiled kernel(but not modified, just compiled). $ sudo qemu -m 512 -enable-kvm disk.img -nographic -append "console=ttyS0 root=/dev/sda1 ro" -kernel bzImage -initrd initrd.img-2.6.37
Just to make sure few things: 1. are you really going to setup serial console only guest? because I saw that nographic and console=ttyS0 2. and the initrd, is that the correct initrd that is built against your kernel?
And I got result like this.
[ 2.687558] EXT4-fs (sda1): INFO: recovery required on readonly filesystem [ 2.688085] EXT4-fs (sda1): write access will be enabled during recovery [ 2.691679] EXT4-fs (sda1): recovery complete [ 2.944387] EXT4-fs (sda1): mounted filesystem with ordered data mode.

just a guess: maybe it didn't freeze...it just display things but toward serial console.... for a test, I suggest (untested) to dump out -nographic and instead use buit in qemu serial console. Switch to it by pressing Ctrl-Alt-3 and see if there are message showing there... -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
