similar to: Supermin appliance changes

I spent the last couple of days rethinking how we go about building the appliance, and the difficulties we have porting that to other Linux distros. I've come up with a much better way that works better and faster on (so far) Fedora and Debian (probably on Ubuntu too, not tried it), and should be much simpler to port to other distros. The current way is to do: +------------------+

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

Supermin is a tool that we use to create and distribute the tiny libguestfs appliance. The tool has been in development since 2009 and was renamed from ‘febootstrap’ to ‘supermin’ in 2013. To find out more about this tool, see: http://libguestfs.org/supermin.1.html I have just released supermin 5.2.0. This is a stable branch version. Previously we didn't really have a split between stable

Hi Rich, I got an error: > supermin helper [00000ms] visiting /usr/local/lib/guestfs/supermin.d > supermin helper [00000ms] visiting /usr/local/lib/guestfs/supermin.d/base.img > supermin helper [00000ms] visiting /usr/local/lib/guestfs/supermin.d/daemon.img > supermin helper [00000ms] visiting /usr/local/lib/guestfs/supermin.d/hostfiles > supermin helper [00012ms] visiting

This patch changes libguestfs to use the ext2-based appliance, cached if possible. I've tested this with the alpha version of febootstrap from here: http://koji.fedoraproject.org/koji/buildinfo?buildID=191338 and it at least passes the tests. There are some hacky bits right now: (1) We add the root -drive option last on the command line, then (in the initrd) reverse-search through the

http://libguestfs.org/download/binaries/appliance/ This could be interesting for people trying to compile libguestfs on platforms which don't yet support febootstrap. I suspect it may also be useful for Debian. I'm not suggesting that Debian uses a binary appliance, but instead of having update-guestfs-appliance build a supermin appliance, it could build a fixed appliance (in two steps,

Rich, So, I tried to build the simple supermin app. from your blog. I can confirm that I did get to the shell when I invoked qemu-kvm. I used the standard qemu-kvm cmdline (but appended a serial console). This boots fine. ######################################################## [root at moon appliance-test]# qemu-kvm -kernel kernel -append "console=tty0 console=ttyS0,115200" -initrd

This patch series adds support for outputing an ext2-based appliance from febootstrap-supermin-helper. The usage is very simple, you just add '-f ext2' flag and the name of the appliance file that you want to write to. The implementation uses libext2fs, which is a very low level way to create ext2 filesystems from scratch. We'd like to use libguestfs, but that's an obvious

Rich, this wasn't operational. First of all, the image on my version of RHEV-H is kept in other directory. So I did that: 1. $ export FEBOOTSTRAP_KERNEL=/dev/.initramfs/live/vmlinuz0 2. $ echo $FEBOOTSTRAP_KERNEL /dev/.initramfs/live/vmlinuz0 3. $ libguestfs-test-tool ************************************************************ *

Use febootstrap-supermin-helper's new -u and -g command line options to setuid, rather than doing it in libguestfs. This resolves an issue with the generation of the cached appliance checksum. The checksum was being generated by a call to febootstrap-supermin-helper through popen(). Unfortunately, a bash misfeature meant that euid would be reset to uid, and the checksum was generated for uid,
