* New 'lvremove', 'vgremove', 'pvremove' commands.
 
* Add really working support for NTFS and FAT.
 
* Add really working support for CD-ROMs and DVDs.
 
* Add <code>--ro</code> option for read-only mounts in guestfish.
 
* New 'set-e2uuid', 'get-e2uuid', 'set-e2label', 'get-e2label' commands for setting ext2/3/4 UUIDs and labels.
 
* New 'debug' command for debugging daemon internals.
 
* Guestfish recipes.
 
* Many bugs fixed (note: including a data corruptor that affected FileOut transfers, so upgrading is recommended).
 
  
Version 1.0.10 was announced just last week (FWN#173<ref>http://fedoraproject.org/wiki/FWN/Issue173#New_Release_libguestfs_1.0.10</ref>). Also see Richard's many blog posts

Virtualization

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

Contributing Writer: Dale Bewley

Enterprise Management Tools List

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


Fedora Virtualization List

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

Virtualization Test Day

The Fedora 11 "Test Day"[1] for virtualization[2] took place on Thursday May 7th.

Mark McLoughlin thought[3] "we made heaps of progress today. To give you an idea of what went on today, see below for the list of bugs that were filed during the test day." See the post for a concise list of bugs revealed during testing.

Fedora virt status

Mark McLoughlin posted[1] another informative Fedora virtualization status report. For those who live life beyond the bleeding edge, Mark points out "F12 tracker bugs have been created.[2] The F12 blocker and target bugs depend on the F11 counterparts. The idea is that if we don't fix a bug in F11, it's automatically on the F12 tracker but we still have a list of bugs worth fixing in a post-GA F11 update."

Read the full post for more coverage of developments and useful bug summaries.

libguestfs on non-Fedora Platforms

Charles Duffy described[1] some "personal hackery" created to solve the same problem Package-x-generic-16.pnglibguestfs (FWN#174[2]) solves, but by way of a different toolchain. Charles wanted to build libguestfs on his platform and he asked, "is my goal reasonable, or am I better off sticking with my in-house solution for the time being?

Fedora Xen List

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

Experimental Dom0 on Fedora 11

Pasi Kärkkäinen reports[1] success with a dom0 kernel using Fedora 11 Rawhide. "I'm able to run Xen paravirtual (PV) domUs, install new domUs using virt-install and also install and manage domains with virt-manager."

The environment used was:

  • Fedora 11 (rawhide as of 2009-05-05)
  • Xen included in F11, no external patches (xen-3.3.1-11.fc11)
  • xen-tip/next pv_ops dom0 kernel as of 2009-05-06, Linux 2.6.30-rc3.
  • All the rest was standard stuff included in Fedora 11 aswell

Michael Young continues[2] to post experimental dom0 kernels to a yum repo[3].

Libvirt List

This section contains the discussion happening on the libvir-list.
