Comment # 10 on bug 919154 from Neil Brown

Looks more like a general networking problem than an NFS problem.

I can see:

Feb 26 08:34:27 domu01 kernel: Initialising virtual ethernet driver.

and then

Feb 26 08:34:37 domu01 wickedd[426]: eth0: Notified neighbours about IP address
10.1.10.1
Feb 26 08:34:40 domu01 wicked[428]: eth0            up

so it appears that eth0 is configured as 10.1.10.1, but

Feb 26 08:34:49 domu01 kernel: nfs: server nas01.lan not responding, timed out

suggests that the server cannot be contacted, and 

> Booting to kernel 3.19, the guest is no longer accessible via network. 

seems to confirm that.  Has anything changed in the "Virtual ethernet driver"
between 3.18 and 3.19??
