We also support running the tools from memory images which you can
capture using the QEMU "memsave" command (see the '-t' option). No
libvirt required for that, _but_ to see any interesting stuff you'd
need to capture the entire guest memory which could obviously be quite
large.
You could do 'virt-mem capture' which captures just the bits of memory
that contain interesting data, and that reduces the amount of data you
need to capture substantially. Unfortunately I broke 'virt-mem
capture' in the latest release by accident, and in any case it
requires libvirt to do the capturing.
I think the message here is, install libvirt & be happy :-)
Rich.

virt-top is 'top' for virtual machines. Tiny program with many
powerful monitoring features, net stats, disk stats, logging, etc.
