That's not good.

But it happens randomly, sometimes I can create DomU in the first
attempt, some times it takes 3-5 attempts. I've tried creating DomU
manually with debootstrap, but with same result.

So you're saying that using debootstrap manually, without xen-tools
causes a freeze?
That suggests to me that the xen-tools are not at fault, since they
also eventually delegate most of the work to debootstrap.

I've disabled /lib/tls and tried booting with "noapic nolapic
acpi=off", but no luck.

I'd suggest it might be network/disc related. Since the kernel
is old in real terms there are sometimes issues. Until I upgraded
my Sid system to the 2.6.20x kernel I found Xen would randomly
crash on heavy I/O, or network traffic.

I haven't reported it as a bug yet. Most of all because of it
happens so random and cause I'm not sure of if the problem lies with
xen-tools, debootstrap or a third option.

I think a xen-specific issue, since it is hard to see how debootstrap
could crash your system.

Another thing, xen-tools ignores when I define a role,
"--role=basic". I also tried the ones that comes with the xen-tool,
such as "gdm". I also tried to define --roledir and the absolute
path to the role, but no luck. The skeleton directory works fine
though...

That sounds like a bug. Report it to the BTS or I'll probably
forget to take a look properly. Still if you're running Etch you'll
not see the fix unless you use the etch backported package available
from my site / the homepage.

(Hmmm I've not uploaded the current release just yet. Will do that
today.)
