Re: [Xen-users] Guest CentOS statistic

[George Shuklin <george.shuklin@xxxxxxxxx>]

AFAIK xentop (xm top - is alias for xentop) displays VM activity with
included I/O time of backend drivers in dom0.

Somewhere in internets I saw document about xentop, and authors note
that backend IO time usually does not count as guest VM time (so xentop
solves this).
