ConditionVirtualization= checks if systemd runs in some sort of guest. It is not supposed to detect host capabilities. The current implementation happens to work because systemd-detect-virt from v208 returns also 'xen' in a dom0. In v210 and later 'none' is returned and no service files will be started. Adjust the checks to detect a dom0 vs. native boot. Mounting xenfs depends on /proc/xen, but should only be done for pvops because xenfs exists only there. All other service files should not be started in domU. The file /proc/xen/capabilities exists in both dom0 and domU in a pvops kernel, but only in dom0 it contains 'control_d'. The existing ExecStartPre= check will prevent starting in a domU. ConditionVirtualization=!xen is true in a dom0. But this check is broken in systemd v208, so its not used.
