Re: Packet loss between Xen machines
|[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]|
Pinging from one domU other domUs shows dropped packets, which is how we initially discovered something odd was going on. It also happens pinging to the domUs from other physical machines.
netstat -i in dom0 shows dropped packets (TX-DRP) on the vif devices. Within the domUs it comes back with zeros.
It only seems to happen under fairly heavy load.
The machines in question are on the same bridge xen. That bridge has separate subnets and one domU is a router that routes between them (and performs LVS functions).

what evidence do you have of packet loss? between the net and the machines or between machines bridged together with xen?

We are experiencing some packet loss between xen machines which we haven't seen before. Is this a problem anyone's run into before and/or has ideas on how to diagnose the issue?
The setup is CentOS 5 xen-3.0.3-80.el5_3.3
