Virtualization

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

Contributing Writer: Dale Bewley

Fedora 10 Virtualization Features

The Fedora 10 release includes a number of virtualization enhancements[1] over previous releases.

Enterprise Management Tools List

This section contains the discussion happening on the et-mgmt-tools list

Connecting to VNC Console on Remote System Installs

While executing virt-install on a remote system, Stephan found[1] that the installer created a VNC service listening on 127.0.0.1, and wanted to know how to connect to this service or move it to a public interface on the remote system.

Daniel P. Berrange answered[2] that modifying the vnc_listen parameter in /etc/libvirt/qemu.conf will affect the IP used, but this isn't necessary. The virt-viewer application will automatically tunnel[3] VNC connection over SSH.

virt-viewer --connect qemu+ssh://root@remotehost/system centos1

Specifying Installation Media URLs

Enzo Medici became[1] frustrated while trying to provision Xen domUs with virt-manager. "What constitutes a valid install media URL?" "How do you get a valid install media URL for a particular Linux distribution?"

Cole Robinson explained[2] "We actually don't have support in the backend for fetching kernels from Ubuntu trees" yet. "This may work at the moment though since it could be detected as a debian tree." Cole then described the installation URLs for some popular distributions.

  • For Fedora, it has varied a bit for different releases, but basically whatever ends in {ARCH}/os:
http://download.fedora.redhat.com/pub/fedora/linux/releases/9/Fedora/x86_64/os/
  • CentOS is similar, but seems to have ARCH and os reversed:
http://mirrors.cmich.edu/centos/5/os/x86_64/
  • Debian/Ubuntu trees are everything up to the install-{ARCH} dir:
http://us.archive.ubuntu.com/ubuntu/dists/etch/main/installer-i386

Fedora Xen List

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

Xen No Graphical Console and CentOS

While creating a domU on CentOS 5.2, Jason passed --nographics to virt-install and received the error message: No console available for domain. Investigation /var/log/xen uncovered: Could not initialize SDL - exiting.

Cole Robinson responded[2] that "This is actually a known bug: xen doesn't abide nographics and tries to init SDL. This will almost always fail if run through [CentOS] 5.2 libvirt. This bug will be fixed in [CentOS] 5.3." The --vnc flag may be used as a workaround this crash in the meantime.
