TCP Connectivity Loss in All Virtual Guest Running on An Oracle VM Server (Doc ID 2335897.1)

Last updated on JUNE 15, 2021

Applies to:

Oracle VM - Version 3.4.2 and later
Oracle Cloud Infrastructure - Version N/A and later
Linux x86-64

Randomly VMs stopped communicating(ssh,nfs,etc...) but not the Oracle VM Server.
Packets with slow size(example: standard ping, arp, etc... ) still pass thru, but other tcp/udp packages doesn't.
pings larger than 128 bytes (example 100-byte, 5000-byte) does not work
It could be possible to see net_ratelimit in the messages of the Oracle VM server too.
Rebooting any of the running VM guest fixes the communication in all other VMs.
