My setup:
Workstation Pro 15.5
Host
CPUs: 16 cores, 32 threads
RAM: 128 GB
OS: Cent OS 7.6.1810
5 NICs – 2×40 Gbps, 2x10Gbps, 1x10Gbps
VM
CPUs: 16 threads
RAM: 64 GB
OS: Red Hat Enterprise 7.8
2 VNICs – 2×10 Gbps
I’m trying to transfer UDP packets from Host to VM using iperf command at 850 Mbps bandwidth. In the attached screen shots. I am dropping about 2-3% of my packets. I have MTU=9000 in all the ifcfg files for all the VNICs and NICs.
What configurations do I need to change to stop packet loss between Host and VM?
