Hi Yaniv,

In the best case everything, I would like to replace the 1G with 10G.

The reason is that both NICs are on the same subnet, which would create problems then with both active?

Linux isn't very happy when two NICs are on the same subnet, AFAIK, so indeed, I would not recommend it.

My guess is the RX errors are due to the missing gateway?

No, those are Ethernet level issues.

Currently I can’t reach the p4p1 NIC since the gateway goes through the 1G NIC.

Makes sense. If possible, I'd change this (routing-wise) and just reinstall the host from the oVirt management. That would be the simplest approach.

(but again, I'd do it only after making sure the network is error free).

Cheers,

Before you move, I suggest to look at the errors that you have here. On the 1G you have transferred far more data without errors.

What would you like to move to the 10g? The storage, migration, VM networks?
