virt-top is the sane replacement to xentop. Virt-top looks and acts like the familiar top(1) command, displays virtual machines, and uses libvirt so it works with just about every virtualization system out there. It also has cool features for sysadmins, like you can use it to log stats into a database or spreadsheet (via CSV).
Today I got virt-top working (almost) properly in Japanese. There are some very small display bugs, mainly where I have used fixed lengths (eg. “40 cols”) to display some strings. But basically it works. Here are the Japanese and English “help” screens compared:
You can see there’s a small error next to ”ヘルプ” where the previous line (on the right next to “2″) wraps around, but otherwise it’s the same.
