NOTE: febootstrap 2.7 is *required* for dev versions of libguestfs

Since I pushed this commit: http://git.annexia.org/?p=libguestfs.git;a=commitdiff;h=8700a55d52f25f60f01… febootstrap >= 2.7 is now *required* for all future development versions of libguestfs, ie. versions from git or >= 1.3.12 tarballs. You can get febootstrap 2.7 from here: http://people.redhat.com/~rjones/febootstrap/files/ and there are Koji builds for Rawhide only (at the moment) here: http://koji.fedoraproject.org/koji/packageinfo?packageID=8170 febootstrap itself should be backwards compatible with previous releases, so you can update febootstrap without updating libguestfs if you want. Similarly you should be able to update febootstrap and run both stable and development versions of libguestfs.

[PATCH febootstrap] Pull in febootstrap-supermin-helper (C version) from libguestfs.
by Richard W.M. Jones 13 May '10

13 May '10

This patch is FYI as it needs more testing, although feel free to take a look at it if you want. Background: We'd like to change libguestfs so that the appliance can support optional features. This would mean you could have (for example) a 'libguestfs' base package and a 'libguestfs-xfs' package providing optional support for XFS filesystem tools. This would only apply to the supermin case. Currently the supermin appliance is built out of 3 files: $ ls -1 /usr/lib64/guestfs/ initramfs.fedora-12.x86_64.supermin.hostfiles # text file containing wildcards of files picked up from # the host at runtime initramfs.fedora-12.x86_64.supermin.img # base appliance data (cpio file) kmod.whitelist # text file containing wildcards matching kernel modules There are a number of problems with this: (1) The files have fixed names. (2) The names are rather obscure. (3) You can't have optional appliance modules. The idea would be to replace this with a scheme where the supermin builder looks in a directory and picks out all the files it needs from there. It would look something like: $ ls -1 /usr/lib64/guestfs/supermin.d/ base.img hostfiles optional-xfs.img # installed by libguestfs-xfs package optional-zfs.img # installed by libguestfs-zfs package (Similarly the kernel module whitelist could point to a directory, but we don't need that now and aren't implementing that right away). At the same time we have for a while been maintaining some significant duplicate functionality in febootstrap, cf: http://git.annexia.org/?p=libguestfs.git;a=blob;f=appliance/supermin-split.… http://git.annexia.org/?p=febootstrap.git;a=blob;f=febootstrap-to-supermin.… and: http://git.annexia.org/?p=libguestfs.git;a=blob;f=appliance/libguestfs-supe… http://git.annexia.org/?p=febootstrap.git;a=blob;f=febootstrap-supermin-hel… Since this is a major change to the way the appliance is built, it makes sense at the same time to fold everything into febootstrap and drop the custom libguestfs/appliance/*supermin* scripts. This patch is the first part of this plan, porting the relevant functionality from libguestfs into febootstrap.

[PATCH] Fix import of RHEL 3 kvm guests using kmod-virtio
by Matthew Booth 13 May '10

13 May '10

RHEL 3 doesn't have a dynamic /dev. kmod-virtio creates devices nodes for vdX block devices based on what the major number of virtblk was at the time it was installed. This is, in turn, based on the order the modules were loaded in initrd. To try to preserve this precarious state of affairs, when adding virtio drivers to a new initrd we always load the same drivers as kmod-virtio in the same order. --- lib/Sys/VirtV2V/Converter/Linux.pm | 8 +++++++- lib/Sys/VirtV2V/GuestOS/RedHat.pm | 8 ++++---- 2 files changed, 11 insertions(+), 5 deletions(-) diff --git a/lib/Sys/VirtV2V/Converter/Linux.pm b/lib/Sys/VirtV2V/Converter/Linux.pm index df7c969..6c50cd1 100644 --- a/lib/Sys/VirtV2V/Converter/Linux.pm +++ b/lib/Sys/VirtV2V/Converter/Linux.pm @@ -332,7 +332,13 @@ sub _configure_boot my ($guestos, $kernel, $virtio) = @_; if($virtio) { - $guestos->prepare_bootable($kernel, "virtio_pci", "virtio_blk"); + # The order of modules here is deliberately the same as the order + # specified in the postinstall script of kmod-virtio in RHEL3.
