Hi!
I'm relatively new to FreeBSD and especially Xen, so please forgive any
misunderstandings and mistakes at my side...
I upgraded from FreeBSD 14.3-RELEASE to 15.0-BETA5 and upgraded all
ports with portmaster, doing a portsnap fetch/extract beforehand.
Reason for the prematurely upgrade were the possibility to create service
jails in FreeBSD 15.0.
Before I upgraded all ports, I deleted all packages and set some options
in /etc/make.conf.
On FreeBSD 14.3-RELEASE and with Xen, domUs where working perfectly fine;
now, on FreeBSD 15.0-BETA5 I get the following error, while trying to
create a VM:

I'm not sure, if I'm correct at this mailing list, or if I should direct
