I did really mean:
xm dmesg
ok xm dmesg is showing the stuff.
thanks for the info.
Does this mean that the printk's print it to the xenstore??

I don't think it is stored in xenstore itself, but yes, it is buffered in Dom0.

Xen can be configured to output it's messages on the serial line, and
it also puts it in a buffer (console ring) for Dom0's attention, xm
dmesg should print all the hypervisors output.
how to enable this???
by default it does'nt print it on the serial console.

add the following command line options to your xen configuration (bootloader config):
com1=115200,8n1 console=com1,tty
