At long last, I'd like to announce beta packages for CentOS 7, available from the community build system.
Great to see Xen coming to CentOS 7 !
I gave the virtx7-44-testing packages a spin on a fresh CentOS 7 install (legacy boot, no efi, as there is no xen.efi). However, I was not able to start any HVM or PVHVM guests. Upon create, the DomU was setup but did not do anything, but instead entered a reboot-loop (Dom ID was increased, but no boot output. No bootloader output on the console, despite everything in the guest setup to display on serial console). The exact same guests worked fine with Xen4CentOS xen+kernel packages for CentOS6. Note, that PV DomUs run fine (tested with CentOS5).
Oh -- you know, not sure how I completely missed this. Anyway, yes, the issue was that the original Xen packages were using the CentOS core version of seabios, which includes a patch which breaks Xen HVM. In -candidate I've built a new version of seabios, which (as you've seen) now works.
