Hi Daan,
Before upgrading to 4.2 we need to register the new system templates for ea=
ch hypervisor with specific names so that during upgrade these new template=
s are set to the system vms.
It is mandatory to upgrade the system vm template if we want upgrade to 4.2=
.

Here seems like you have a Xen cluster. So you need to register xen system =
template with name systemvm-xenserver-4.2.
So for the existing clusters you need to register system vm template per hy=
pervisor.
System template names are for each hypervisor are
1) systemvm-xenserver-4.2=20
2) systemvm-kvm-4.2=20
3) systemvm-vmware-4.2=20
4) systemvm-hyperv-4.2=20
5) systemvm-lxc-4.2=20

Thank you
Harikrishna           =20
