Hi,
Getting an error while booting my guest with -initrd option as in :
qemu-kvm -net nic,macaddr=$macaddress -net tap,script=/etc/qemu-ifup
-m 512 -hda /root/kvm/x86/vdisk.img -kernel /root/mvroot/bzImage
-initrd /root/kvm/mv/ramdisk.img -append "root=/dev/ram0"
No filesystem could mount root, tried : ext3 ext2 ext4 vfat msds iso9660
Kernel panic
#file ramdisk.img
#ramdisk.img: Linux rev 1.0 ext2 filesystem data (mounted or unclean)
I tried with both above initrd and gzipped initrd but same error.
If I try to mount the same file and do a -append "ip=dhcp
root=/dev/nfs rw nfsroot=xxxx:/root/kvm/mv/mnt" instead of -initrd
option, it works fine. So am guessing this is initrd related.
Any help would be much appreciated.
Thanks,
Nirmal

What's the size of ramdisk.img?

I tried with both initrd and initramfs. Sizes are 42314699 and
71271136 respectively. Sizes do seem larger but I created them from
the nfsroot created as part of the build (the nfsroot works
apparently).

See if you can drop the image size as a test. I had to do that recently
to get the kernel/initrd/append option to work. As I recall I was
getting the same error message until I dropped the initrd size.
