I'am using 11.1-STABLE (r321629) as Xen dom0, running under Xen kernel 4.7.2_3. I have sucessfully started appliances built on oldish RedHat kernels (2.6.32-573.18.1.el6.x86_64) without any problems. For Fedora 25 (4.10.8-200.fc25.x86_64) I had to add xen_platform_pci=0 to the config file to get it running. This still seems to be needed. My disk definition for fedora and the RedHats looks like this: '/dev/zvol/zroot/fedora0,raw,hda,w' (xvda seems to work well in place of "hda" for RHEL and Fedora as well) Marcin
