Today at Red Hat Summit in Boston, two of Red Hat’s emerging technology engineers, Dan Barrange and Richard Jones, presented the new tool sets that their team has developed for work with Xen virtual machines (VMs), including command line utilities, which will become part of the oVirt tool set.
According to Barrange, “You won’t have to lock into any particular technology underneath,” because these new utilities don’t require installation on a guest or require administrators to log in. Like the forthcoming Red Hat Enterprise Linux (RHEL) KVM-based hypervisor, these tools can also be launched from disk. “That’s the competitive advantage to using our tools,” says Barrange.
Red Hat engineer Richard Jones says that these new command line monitoring tools allow for a wider range of kernels and filesystems to be used and will offer better Windows support. Some of the utilities featured today include the following:
- Virt-top. A top-like utility for showing stats of virtualized domains (e.g. for reading network traffic, disk throughput, etc.).
- Virt-df . Virt-df is df for virtual guests. Used for checking how much disk space is being used by virtual machines.
- Virt-p2v. A graphical user interface launched from live CD for physical to virtual migration.
A full list of these tools is available at Richard Jones’s website.
Red Hat has developed these tool sets for oVirt, its next-generation virtualization management console. Unlike the current Virtual Machine Manager for RHEL, oVirt creates a small “stateless” image of the host virtualization layer with no local disks or installation necessary.
