Foreword

This page was used to discuss virtualization options at UDS Boston (Hardy).

For documentation on how to use Ubuntu as a virtualization host or guest, please see https://help.ubuntu.com/community/Virtualisation.

Discussion

The state and future of Ubuntu JeOS. - "Ubuntu JeOS Edition has been tuned to take advantage of key performance technologies of the latest visualization products from VMware."

This Virtualization page will also go over information for Xen.

• Integrating Ubuntu Server JeOS Edition into the normal Ubuntu build process.

  Discuss JeOS support for XEN, Parallels, OpenVZ, Linux-Vservers, KVM, QEMU, VirtualBox, Virtuozzo, VirtualIron others Discuss opensource virtualization technologies. What should Ubuntu support?

Use Cases

• What does JeOS offer over a standard Ubuntu install. ??
• How will ubuntu JeOS tools integrate with Xen?
• Is JeOS mature enough to be supported by official ubuntu setup tools, or is it just going to be part of universe for now?
• Server consolidation
  • reproducability for support, testing, documentation, included nested vms, cow files etc
• Server segregation
• disaster recovery - migration of vms
• rapid deployment
• desktop uses, e.g. running multiple OS on the desktop

Ubuntu 8.04

• Pre-installed server/appliance VM will be built as part of standard Ubuntu build process (along with server ISOs)
• JeOS should be one of the tasks from the standard server installation
• JeOS will also be provided as pre-built VM for selected technologies

User Space tools

• What tools are needed to be setup in a quick and automagic manner?

Xen

• Xen should be very stable on Ubuntu 8.04. It has been tested with many existing ubuntu releases. In most cases, apt-get install ubuntu-xen-server, will get a machine all ready to go. The community has built lots of information for guidance on this process, https://help.ubuntu.com/community/Xen . xen-tools makes setting up new guests quite easy. Xen requires no changes to the ubuntu install process, and can simply convert a new ubuntu server install into a ubuntu xen server.

Host solution

For Hardy 8.04: not container.

Next Steps

• Finalize requirements
• Post on ubuntu-devel asking for usecases
