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."

Fedora Xen List

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


Virtualization Tools List

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

New Release virt-manager 0.8.0

Cole Robinson [1] a new Package-x-generic-16.pngvirt-manager[2] release, version 0.8.0.

Virtual Machine Manager provides a graphical tool for administering virtual machines for KVM, Xen, and QEmu. Start, stop, add or remove virtual devices, connect to a graphical or serial console, and see resource usage statistics for existing VMs on local or remote machines. Uses Package-x-generic-16.pnglibvirt as the backend management API.

New features:

  • New 'Clone VM' Wizard
  • Improved UI, including an overhaul of the main 'manager' view
  • System tray icon for easy VM access (start, stop, view console/details)
  • Wizard for adding serial, parallel, and video devices to existing VMs.
  • CPU pinning support (Michal Novotny)
  • Ability to view and change VM security (sVirt) settings (Dan Walsh)
  • Many bug fixes and improvements

The newest releases of virt packages can be found in the Virtualization Preview Repository.
