When running kvmtop I see the following line in the syslog messages:
error : virNetSocketReadWire:1806 : End of file while reading data: Input/output error
The results are shown but it's spamming our syslog.
It's only when ending the kvmtop session but we run it once per minute (with the option -r1) to collect data and put it in colelctd.
[~]# kvmtop --version
kvmtop version 2.1.3
