recompiling xen

recompiling xen

[Michael R. Hines]

I downloaded and successfully installed xen 3.0 for FC4.....

(I have a good deal of kernel programming experience, so feel free to be 
verbose...)

So, I thought I'd throw a printk in a common routine.....say 
alloc_pages......

But after I compile with ARCH=xen and attempt to install the new guest 
kernel image,
I reboot, but nothing happens.

Is there a particular set of steps that I need to follow to recompile a 
guest kernel and
install it?

What kind of error are you getting? And what do you mean by "nothing
happens"?

make world 

should be all you need after the mod.

If you mean that your output doesn't appear, bear in mind that Xen 
stops outputting to the local console when domain0 starts (dom0 steals 
the vga adaptor). Xen will continue to output over the serial line, if 
you have configured that, or try 'xm dmesg' after starting xend.
