Were having similar issues where we are getting some random but frequent network spike with a win VM and wondering if your having progress with this being helpful. we can observe these network latency spike both from pinging from the VM to other devices, and other devices pinging the VM. other VMs (which of note are not under the same load) do not experience these spikes and are all set with the same hardware.

Okay we figured this out. For us, it was simply changing the network device type from E1000E (which was set from a vmware migraiton) to VirtIO after installing the driver package, seems to have fixed the issue.

Heres the last 30 minutes from our ping monitoring. (red mark is one packet dropped) but no pings greater than 15ms now, compared to the spikes which were sometimes >1sec
