=head1 NAME virt-top - 'top'-like utility for virtualization stats =head1 SUMMARY virt-top [-options] =head1 DESCRIPTION virt-top is a L-like utility for showing stats of virtualized domains. Many keys and command line options are the same as for ordinary I. It uses libvirt so it is capable of showing stats across a variety of different virtualization systems. =head1 OPTIONS =over 4 =item B<-1> Display physical CPUs by default (instead of domains). When virt-top is running, use the I<1> key to toggle between physical CPUs and domains display. =item B<-2> Display network interfaces by default (instead of domains). When virt-top is running, use the I<2> key to toggle between network interfaces and domains display. =item B<-3> Display block devices (virtual disks) by default (instead of domains). When virt-top is running, use the I<3> key to toggle between block devices and domains display. =item B<-b> Batch mode. In this mode keypresses are ignored. =item B<-c uri> or B<--connect uri> Connect to the libvirt URI given. To connect to QEMU/KVM you would normally do I<-c qemu:///system> To connect to Xen on the same host, do I<-c xen:///> To connect to libvirtd on a remote machine you would normally do I<-c qemu://host/system> If this option is not given then virt-top connects by default to whatever is the default hypervisor for libvirt, although this can be overridden by setting environment variables. See the libvirt documentation at L for further information. =item B<-d delay> Set the delay between screen updates in seconds. The default is 3.0 seconds. You can change this while virt-top is running by pressing either I or I key. =item B<-n iterations> Set the number of iterations to run. The default is to run continuously. =item B<-o sort> Set the sort order to one of: B (sort by %CPU used), B (sort by total memory), B
