It's failing creating domain on 128.224.147.229:/mnt/data. You must be sure that the IP address is correct. You need to be sure that on 128.224.147.229 /mnt/data is 775, owned by 36:36, and selinux allow public content. Then you need to be sure that you can mount 128.224.147.229:/mnt/data locally. On the host running engine try: mkdir /tmp/test mount -t nfs 128.224.147.229:/mnt/data /tmp/test Then if it works you must ensure it's writable by vdsm:kvm user: sudo -u vdsm -g kvm mkdir /tmp/test/writable sudo -u vdsm -g kvm touch /tmp/test/writable/file If those commands are working, you should be able to create the domain.
