[CentOS-virt] CentOS 5.9 Xen DomU NFS Data Transfer to Dom0 kills network.

Greetings,

I have problem using Dom0 as NFS(v4)-server and DomU as client. When ever the client actually tries to copy data to nfs-server the virtual network (bridge) between the two hosts completely freezes and stops working. After this of course the client hangs waiting nfs-server to answer and server continues to try to contact nfslock daemon on the client.

Dom0 is still accessible from outside trough virbr0 which the client doesn't have access. The problems only come on data transfer as making directories and removing them and doind ls works fine before one tries to transfer data.

Anyone have suggestion what could fix this behavior. Veli-Pekka
