Thank you.
What TCP bandwidth did you get with the gen4 cards?

virtio nic dosent use 10gbe speed.
Hello all.
We are moving from Xenserver 6.5 environment to KVM because we can't use
10gbe speed in our VM's so we decided to test KVM.
To inicial test I've create script, using qemu commands, to build two VM's
and test the nic speed.
Each VM has one nic, using virtio, into it own bridge. In this bridge we
associate one 10gbe physical nic.
They can communicate each other.
