[Xen-users] xen 3.0.4 - 22, 'Invalid argument' when starting domain.

[xensource@xxxxxxxxxx]

Hi,

I have a working installation of xen-3.0.2 under gentoo with kernel 2.6.16.

As I need a kernel >=2.6.19 for my ivtv drivers to work, I took the kernel : 
linux-2.6.19-xen-3.0.4 through hg, and xen-3.0.4_1-src.tgz for xen-tools and 
hypervisor.

Kernel boots OK and xend starts OK.
But, when I want to start a domain, I have in my xend.log :

What's wrong ? What should I check ?
