It does as long as (1) the kernel has Xen PV support (CentOS 6 standard kernel does) and (2) it has the necessary drivers in the initrd (I think this is where the CD image is lacking), then you should, in theory, be able to pv-grub boot to the CD. Alternatively you can boot to the CD on another box first, copy the kernel off to a USB stick, and generate a new initrd with the xen drivers included, then put those on the Xen host and boot to the VM CD image using those in the kernel= and initrd= lines in the domain.cfg file. The other way is to boot to the CD as an HVM domain and install, then convert it to a PV domain afterwards, which is not all that difficult to do. There is a third way which involves using yum to install the @core group plus kernel to an image, then tweak and boot to that as a PV domain. This is how I have done it in the past. > So I'm right back to my effectively unanswered original questions. So > please: I asked a very specific pair of questions, and they remain > unanswered.

Yes, I have done that until I upgraded the CentOS 5 host to CentOS 6 a couple years ago. > And given my deployment issues, does anyone have a base OS > image I can get a copy of? Sorry my image templates that I use are highly customized for my own work, but I have told you three different ways to accomplish it above.
