Hi

As you may've seen from my last post= s I'm struggling to get the setup on my=A0subject=A0line to work withou= t flaws.

I've tried compiling the Kernel from Source, I'= ve also tried Fedora 14, which has a flaky pv_ops Dom0 kernel which DOESN&#= 39;T work at all, but none of these seem to work.

I'm a mid-time XEN user, I just love it and want to= stay away from KVM =A0but the migration path is too rough when you want pv= _ops Dom0, and all seem to be just projects, TODOs and snapshots, nothing r= eally serious IMHO there's lots of misleading info and there are many g= aps on existing howtos, I've read that SuSE has back-ported some stuff = from 2.6.3.x branch into 2.6.18 but I want native and I don't want to b= e toying around with Debian'ish stuff in production=A0environments.

I'd like to keep using RH like system because of th= eir robustness and because I'm used to work with it as a RHCE.

Please, would you help me find a distro which would integr= ate

RH like=A0
XEN 4.0.1
pv_ops Dom0 ke= rnel

I want to run telephony stuff on them and tho= I kinda got my Openvox A1200P card to work 50% of the times now with xen 4= .0.1 it won't work but I guess that's because I'm using Kernel = 2.6.18.x with XEN 4 which is not recommended.

Any advise will be deeply appreciated.

Thank you.

Hi,
Has there been any development in the OVF support for Xen?
It was in the roadmap of Xen 3.4 (http://www.xen.org/downloa= d/roadmap.html)
