Re: [Libguestfs] P2Vs seem to require a very robust Ethernet
There's something ugly going on with the network. Take a look at this experiment. I
have a bunch of unused local disk space on my thing2 host and I wondered what would happen
if I tried copying that large VM disk image from that RHEV Export NFS server to a local
disk by hand? So I tried it - see below and then some comments after that.

And my window I pasted in above doing the copying is hung. Looking in other windows, it
copied about 204 MB to my local /data/greg directory before hanging. Ctrl/C doesn't
work, it's just hung. After a couple minutes, it finally responded to my CTRL/C.
From another window, trying:
brctl show
also hangs. After several minutes, it comes back to a shell after CTRL/C, but never shows
me any brctl output.
Go figure.
Been a long night. I'm going to grab some sleep.
