Thanks for the reply, it turned out to be a intermittent issue with the underlying host hardware I was using in my dev environment, we actually upgraded our production environment and everything is fine so far. We are humming along on 4.3.3 just fine.

      I have an oVirt dev environment, and I have one host and the engine

172.16.12.0/24 when I start a Windows 10 VM, 1903 or 1809 I start
getting issues all across that sub-net. It happens to be my server
subnet. Now we have not had any catastrophic interruptions because of it
but the behavior is weird. But its weird, this dev environment when I
bring up a windows 10 VM on the ovirtmgmt network riding on the same
vlan I experience this insane packet loss when I am pinging from my
desktop machine to my dhcp server which is also on the 172.16.12.0/24
subnet.

Does the problem still exist?
If yes, what is the CPU utilization of the VM's physical host?

The reason I am emailing the mailing lists is we had planned on moving
to 4.3.3 tonight, but I cannot confirm if this weird network issue is
some how related to 4.3.3 and the way its handling networking. Or if we
have something wrong in our network. Just wanted to know if anyone else
experience weird issues with VMs windows or otherwise on the ovirtmgmt
network in 4.3.3.


All the VMs in this dev environment are brand new installations of their
respective base OS. Windows and CentOS7


Thank you.
