Hi, Dan

My patch is not completely committed. I make a small patch. This is the part which wasn't committed.

Hi, Dan and all

cmdline's sample is the bellow

---------------------- kernel = "/boot/vmlinux-2.6.12-xenU" ramdisk = "/boot/initrd-2.6.12-xenU.img" memory = 256 name = "rhel4-2" disk = [ 'file:/home/takebe/rhel4.img,hda1,w' ] root = "/dev/hda1 ro" extra = "nomca nosmp xencons=tty0 console=tty0 3" -----------------------

Today I'm trying to build and boot new changeset. But I cannot boot DomU. I will update my recipe, please wait.

My environment is ; Machine : Tiger4 Dom0&DomU OS : RHEL4 U2 changeset : 8424

Best Regards,

Akio Takebe

Committed. I added some code for backwards compatibility that uses the old cmdline if none is specified.

Could you post instructions on how to change the cmdline for domU boots? Eventually after everyone starts using this correctly, we should remove the code for the old default.

Thanks, Dan
