Re: [Xen-users] XEN boot messages not visible on console

[Richie <listmail@xxxxxxxxxxxx>]

I think it is that com1 defaults to the standard irq/address but you can 
redefine it
menuentry "Xen 4.0 / Ubuntu 10.4 kernel 2.6.32.10-xen7 pvops IOMMU SERIAL" {
insmod ext2
set root='(hd0,2)'
search --no-floppy --fs-uuid --set 321dedfa-be48-4b4d-bff0-0e5ecce240fd
multiboot /boot/xen-4.0.gz dummy=dummy iommu=1 dom0_mem=1024M 
com1=19200,8n1,0xe480,17 console=com1
module /boot/vmlinuz-2.6.32.10-xen7 dummy=dummy root=/dev/sdc2 ro 
xen-pciback.permissive 
xen-pciback.hide=(07:01.0)(01:00.0)(00:1a.0)(00:1d.0) console=hvc0
module /boot/initrd.img-2.6.32.10-xen7
}
