Ah right, I see.  libvirt 0.1.8 is too old for virt-top.  You need 
minimum libvirt 0.2.1.  The reason is because we need the vcpu info 
stuff which was only added in libvirt 0.2.1 
(http://libvirt.org/hvsupport.html).

One simple solution is to compile a local copy of libvirt and point the 
binary at it, something like this:

   LD_LIBRARY_PATH=/my/local/copy/lib virt-top

By the way, you can narrow down these problems by doing:

   virt-top --debug somefile

which will write debugging info to the file (basically, everything which 
would normally go to stderr, but in a curses program stderr isn't really 
available).

Rich.
