Hi,
    I am trying to upgrade my Xen host (Dom0) and are having troubles getting it to work.

I think that it has booted into a kernel that supports Xen (running 'xl info' does list some Xen capabilities), but I have three problems (that I have found so far).

Firstly, the "libvirtd" daemon doesn't start on bootup (and as a result all 'virsh' commands fail). It is set to auto-start (systemctl enable libvirtd), and can be manually started (systemctl start libvirtd), but it will not auto-start on reboot.

Secondly, Once I have manually started libvirtd, when I try to define a domain it gives me an error "could not find capabilities for arch=x86_64 domaintype=xen" and I haven't yet been able to define any domains. This domain type works fine on Fedora 21.

Thirdly, I am unable to convert to/from xml config format, it gives me the error "error: invalid argument: unsupported config type xen-xl" however the format "xen-xl" works fine on the Fedora 21 machine.

All of those are libvirt related. You might have better luck asking on libvirt list.

Xen has its own domU configuration format, which you did not use.

https://libvirt.org/drvxen.html says

    <type>hvm</type>

... as opposed to what you wrote

    <type arch='x86_64' machine='xenfv'>hvm</type>

... so that might be relevant. In any case, You might have better luck asking on libvirt list.
