Re: problem using compiled kernel -- Sisu

[Sisu Xi <xisisu@gmail.com>]

Hi, Jeremy:

Thanks for the reply! i am using ubuntu 10.04, so grub2 is used here.
I checked my configure file, and it is:

menuentry "Debug Xen 4.0 / Ubuntu 10.04 kernel 2.6.34 pvops" {
insmod ext2
set root=(hd0,3)
multiboot (hd0,3)/boot/xen.gz dom0_mem=1024M loglvl=all
guest_loglvl=all sync_console console_to_ring com1=115200,8n1
console=com1
module (hd0,3)/boot/vmlinuz-2.6.32.16 console=hvc0 earlyprintk=xen nomodeset
module (hd0,3)/boot/initrd.img-2.6.32.16-xen.img
}

it already contains the console=hvc0 part..

what info are missing?

thanks very  much!

Best!

Yours,
sisu
