By the way, I (the main Remus developer) have spent the last couple of
weeks refreshing Remus to the latest Xen and getting HVM support in
place. It's just about ready -- we're just working out a few kinks in
the blktap2 port. You can expect a new release in the next few days.

That's AWESOME!
I wanna build a non-stop Xen cluster with Remus for hosting paravirtualzed
Linux firewalls...

This projects  already existed before xen 3.4. What kind of support to high
availability,specifically, the version 3.4 has?

Xen 3.4 come with Kemari and Remus? I think not, so.

If you're mentioning something that already comes with Xen 3.4, there is none. 
I guess there is a commercial product, but I'm not that familiar.  Regarding the 
next version of Xen, Kemari is hosting trees which track Xen unstable tree, and 
we've been proposing for integration so far.

No there is no complete HA solution integrated into 3.4 branch. Hopefully
this will be a feature for the next stable release.

Ok, thanks...

But where Xen 3.4 differs of Xen 3.3 in HA terms?

Xen 3.4 has some RAS features -- CPU offlining and memory offlining, and
some support for machine-check exceptions. It's not all really joined
together for easy user deployment however.
