There is a further problem, most likely related to this one, in attempting to
run an Athena virtual machine from off-campus. I have an Athena virtual machine
that works reliably on campus (at least for time periods up to several hours).
I can suspend and resume it correctly (though only tested over a few hours).
When I copy the machine to one of my home computers (I have a Verizon
FIOS connection) and try to restore the machine, network and AFS are
dead and unlike Bill's experience, I can't restart them with "ifup
eth0", "network start" or "openafs start" commands.
I did a further test- I put a working Athena virtual machine on a laptop on
campus. I verified that I could suspend/resume the machine repeatedly and
reliably. I then suspended the machine, took it home and resumed. Again
no network or AFS, and no way to restart them.
I tried turning off both the PC firewall and the router firewall on my
home system to see if those might be causing this. Didn't make any
difference.
I checked /etc/sysconfig/network-scripts/ifcfg-eth0 in the virtual
machine and there was no HWADDR entry. The IPADDR entry was
correct. My virtual machine has a fixed IP address, like Bill's. I set
this and the hostname in /etc/athena/rc.conf in the virtual
machine. Most on my testing was on Windows host OSes, but I
experienced the same thing at home with a Linux (Fedora 7) host OS.
