So I've just been contacted by RedHat about OS licensing: they took down my name when I told them that doing Xen for RHEL 4 was prohibitively expensive with their one license/guest domain, and I was currently using CentOS on quite a few systems because of this and because up2date sucks so very hard, and because RedHat support is less useful than my own experience and the open source venues for particular software (like Xen itself!)

RHEL5 uses yum, not up2date.  An improvement, IMHO.

They listened, and called me back to give me pricing for RHEL 5 servers and domains. I've played with the 4.92 beta, and it's not bad: the hypervisor is still fairly silly in a bunch of ways because it prevents much control over the paravirtual environment or with setting up multiple exported images as multiple disks in the Xen environment, or with exporting one mountable image as one partition instead of building internal partitions. (Useful for some tasks, trust me on this!)

As far as I can tell, all of the limitations in the RedHat gui can be overcome by using the command line tools; RedHat includes the standard Xen xm tools; it just has a nice gui on top that can handle a subset of the xm tool's functionality to make things easy. If you drop to a shell prompt, the xm tools work just like on a standard Xen3 install.

But it's not bad. Anyone else out there planning on using it?

I have one client that has been using it since beta2; if you have money and don't have the ability to identify or retain good Linux nerds, RedHat is an excellent choice. The support my client gets is pretty good.

I do not know what this costs, though I imagine it's quite expensive. Still, I'm not complaining about the service (and from me, that's something of a compliment. I'm a loud and harsh critic of mediocre support services.)

Me, I don't have money, so I'll try the CentOS 5 variety out, if nothing else, then to get some practice. but I will probably end up using slack for my Dom0 and whatever the customer wants for the DomU.

(does anyone use DSL or another embedded distribution for the Dom0?)
