Virtualization

In this section, we cover discussion of Fedora virtualization technologies on the @fedora-virt, @fedora-xen-list, @libguestfs, @libvirt-list, @virt-tools-list, and @ovirt-devel-list lists.

Contributing Writer: Dale Bewley

Fedora Virtualization List

This section contains the discussion happening on the fedora-virt list.

Distributing I/O Load Among Guests

Dennis J. asked[1] "What is the best way to deal with I/O load when running several VMs on a physical machine with local or remote storage?" "What I'm primarily worried about is the case when several VMs cause disk I/O at the same time." "What is the best way to soften the impact of such a situation?"

Pasi Kärkkäinen suggested "If the IOS are not split evenly between VMs, you could use some tool like dm-ioband[2] to make sure IOs are split fairly between VMs. Or then get faster disks. Single 15k rpm SAS disk will give you up to 350 IOPS, so it's 2-3x faster than 7200 rpm SATA."

Richard Jones concurred[3] "For KVM, each VM isn't really any different from a host process, so you have to deal with them the same way that you'd deal with having lots of host processes doing I/O. So: lots of spindles, expensive I/O hardware, etc."

Virtualization Tools List

This section contains the discussion happening on the virt-tools-list list.

The very newest releases of virt packages are available (for testing purposes only) in the Virtualization Preview Repository before they become generally available.

New Release virt-manager 0.8.0

Cole Robinson [1] a new virt-manager[2] release, version 0.8.0.
