If you have a reason to prefer not to have /usr/sbin in the path, I
believe you can also run /usr/sbin/xentop instead of /usr/sbin/xm top to get
around that error. I could be wrong on the location of the xentop
executable, but said executable works for me on a machine where xm top does
not. I'm running F8 on that machine and assume that the Xen packages
provided with it are the cause, but I don't worry about it since, to the
best of my knowledge, all xm top does is call xentop (and especially since
F8 is now out of maintenance anyway).

PATH=/usr/sbin:$PATH xm top

Nathan,
That may provide what I'm looking for -- however xm top does not seem to
function properly. all the other xm commands work fine.

Is the data in xm top not useful under the NETTX and NETRX columns?

Subject: [Xen-users] network usage gathering
I've run into a problem gathering usage for my xen virtual systems. With my
old model I used to gather all network usage via my cisco devices using the
the counters for each port. Each system had it's own port on the switch, and
I tracked network usage accordingly. Now that I'm using xen for virtual
systems, and multiple vm's share the same switch port, i'm not exactly sure
what my best option is for tracking usage.
I thought I may be able to setup vlans on the switch, and bind each vm to a
different vlan using vconfig... but it seems like there has to be a better
solution than that. Has anyone done anything like this? Any insight would be
greatly appreciated.
