Intermittent packet loss after VM startup. 4.3.3
I have an oVirt dev environment, and I have one host and the engine as well as VMs running on a network that looks something like this 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. 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. -- Jacob Green Systems Admin American Alloy Steel 713-300-5690

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

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. On 05/28/2019 02:43 AM, Dominik Holler wrote:
