[Libguestfs] P2Vs seem to require a very robust Ethernet

[Greg Scott]

This time after roughly 7 1/2 hours, the exact amount of disk space used in the NFS Export domain.  And then as soon as I run df a couple of times, now the disk space usage starts to climb again.  One other symptom to note - that 3rd df took nearly 2 minutes to respond.  See the date commands before and after.  The first 2 df commands responded immediately.  After the 2nd df command, I looked at virt-p2v-server with strace again.

I don't think my RHEV hosts are going into standby.  If they were, then why would my df and strace commands to a guest VM on one of the hosts respond immediately?  I think the Storagetek NFS server goes offline and somehow when I either do a df command or strace against virt-p2v-server, it goes back online again.  

We'll know more when we try this same thing with a different NFS server hopefully after the sun comes up today.
