Re: [ovirt-users] oVirt Engine 4.0.5 and CentOS 7.3 Instability

16 Jan 2017

      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.

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.
