 Yes, oVirt engine Virtual machine run on Hyper-V hypervisor. Now, i
am
 using Hyper-V centos kernel drivers, but for some reasons (better
 integration on spashot, backup, etc ) microsoft recomends to use LIS.

 Later a will migrate this vm to oVirt enviroment. Maybe running ovirt
 engine virtual machine with Production enviroment running on a second oVirt
 enviroment.

I suggest self-hosted Engine. Sounds exactly what you are looking for.

 Hello Again Pavel and oVirt Jedi Masters,

 Last week I finally found the problem with my oVirt enviroment and does
 not have relation with oVirt itself.

 When I upgrade ovirt engine Virtual Machine CentOS 7.2 to CentOS 7.3 i
 also update Hyper-V Linux Integration Services from 4.1.2 to 4.1.3 ( Add
 support to CentOS 7.3 ). Well, after LIS 4.1.3, Virtual Machine begin to
 drop packages. :-(

 Is there any reason you need them installed at all?
 Y.

 Seem´s that Microsoft done something very wrong with virtual ethernet on
 this version.

 I unistall LIS 4.1.3 and everything are ok now.

 Thanks again Pavel.
