To run a kernel as dom0, it needs to be compiled with dom0 support, and RHEL specifically disable that in their kernels from 6 onwards. You might consider using the CentOS Virt SIG kernel (and Xen packages even), or building your own kernel with dom0 support enabled. https://wiki.centos.org/HowTos/Xen/Xen4QuickStart -George _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxx https://lists.xen.org/xen-users
