Why does the toplevel Makefile process appliance/, and creates supermin.d during make install, whith configure --disable-appliance? I have to double check what actually happens, it seems it causes startup failures if the resulting binary packages are started on a host that happens to have supermin installed. Olaf

By passing root=UUID=... to supermin, we make the appliance boot process less sensitive to the non-deterministic process of scanning SCSI disks (of which much more to come). This patch should be tested alongside the supermin patch posted here: https://www.redhat.com/archives/libguestfs/2017-April/msg00174.html which in turn requires this supermin patch series:

[First attempt to send this using git send-email didn't work because of SMTP routing problems] Hilko, This is my experimental patch to remove update-guestfs-appliance from Debian. With this patch, libguestfs builds with a supermin [version 5] appliance in /usr/lib/guestfs/supermin.d: $ ll -h /usr/lib/guestfs/supermin.d/ total 884K -rw-r--r-- 1 root root 94K Mar 15 12:18 base.tar.gz

Instead of specifying a device name (eg. root=/dev/sdb), this permits specifying an ext4 volume UUID (root=UUID=12345678-...). This allows the appliance to be robust against the non-determinism of SCSI device enumeration. --- init/init.c | 226 +++++++++++++++++++++++++++++++++++++++++++++++++++--------- 1 file changed, 192 insertions(+), 34 deletions(-) diff --git a/init/init.c b/init/init.c

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I was testing oz/imagefactory on 32 bit arm, you have to have kernel-lpae installed to run kvm. while you can have the regular kernel installed also. You end up having the system booting the regular kernel and you do not get kvm. Ideally supermin will work with the lpae kernel.

Hi, I remembered reading about Intel Clear Containers [1], and Hyper/Qboot [2] that support startup times measured in the hundreds of miliseconds range. On an AMD FX(tm)-8350 'guestfish -a /dev/null run' takes ~4s when run the 2nd/3rd time: real 0m4.152s user 0m2.120s sys 0m0.564s Are there any plans on applying these improvements to the supermin appliance? I did some quick tests on

Move the "FIXED APPLIANCE" section from libguestfs-make-fixed-appliance(1) to the general guestfs(3), so it's more visible and less hidden in the documentation of a rarely-used tool. Expand the FAQ question about libguestfs without supermin, mentioning the build options needed and pointing to the aforementioned new section. --- appliance/libguestfs-make-fixed-appliance.pod | 28

Move the "FIXED APPLIANCE" section from libguestfs-make-fixed-appliance(1) to the "INTERNALS" section of guestfs(3), so it's more visible and less hidden in the documentation of a rarely-used tool. Also slightly improve it. Expand the FAQ question about libguestfs without supermin, mentioning the build options needed and pointing to the aforementioned new section. ---

After supermin has finished running, the initramfs files sit around occupying swappable memory but serving no further purpose. This saves a little memory, at the cost of about 1ms of extra boot time. --- init/init.c | 50 ++++++++++++++++++++++++++++++++++++++++++++++++-- 1 file changed, 48 insertions(+), 2 deletions(-) diff --git a/init/init.c b/init/init.c index 733d66e..5ac53e9 100644 ---

I've ported the supermin appliance capabilities from libguestfs into febootstrap >= 2.5: http://git.et.redhat.com/?p=febootstrap.git;a=commit;h=76b7711268a6b0c0929952ee261821825589a165 Once that has rolled out into Fedora (in about 2 weeks) I will remove the code from libguestfs and just have it use febootstrap. There should be no visible changes, but developers will need to upgrade to

Hi I have compiled libguestfs-1.26.1 on powerpc ubuntu using supermin_5.1.8-2_powerpc.deb as it dependency package. When I'm executing the binary libguestfs-test-tool on powerpc ubuntu,I'm getting supermin error...
