>I'm not sure I understand the layering - hyper-V on oVirt or vice-versa?

the layering: oVirt host -> Hyper-V_VM on oVirt -> VM on Hyper-V_VM

CentOS based on linux kernel. I manual modified linux kernel parametrs.

oVirt-engine based on oVirt API. How to manually change the parameters
of ovirt-engine through API?

>In any case, I assume an additional host is needed, the host hosting
the Hosted-Engine VM cannot be changed with those parameters when the HE
is up.
>Y.

It's impossible, the second host is now - Hyper-V with working VM's.

Thanks for the quick response.

>You probably need an additional host.

I'm migrating from Hyper-V at the moment there is no way to add a second
host.
