A monitoring tool for black box virtual machines from KVM hypervisor level
This release mostly focuses on stability and bug fixing. For simplicity the branch profiler is merged into the master with this release (why the commit log is lengthy).

Version 2.1 contains several bug fixes, and introduces a more complete list of metrics in the collectors. For more information about metrics, collectors, usage guides and more, please follow these links:
Usage:
kvmtop [OPTIONS]
Monitor virtual machine experience from outside on KVM hypervisor level
Application Options:
-v, --version Show version
-f, --frequency= Frequency (in seconds) for collecting metrics (default: 1)
-r, --runs= Amount of collection runs (default: -1)
-c, --connection= connection uri to libvirt daemon (default: qemu:///system)
--procfs= path to the proc filesystem (default: /proc)
--verbose Verbose output, adds more detailed fields
--cpu enable cpu metrics
--mem enable memory metrics
--disk enable disk metrics
--net enable network metrics
--io enable io metrics (requires root)
-b, --batch [DEPRECATED: use --printer=text instead] use simple output
e.g. for scripts
-p, --printer= the output printer to use (valid printers: ncurses, text,
json) (default: ncurses)
