SystemImager 4.1.6 (unstable) released
SystemImager is software which automates Linux installs, software distribution, and production deployment.
SystemImager makes it easy to do automated installs (clones), software distribution, content or data distribution, configuration changes, and operating system updates to your network of Linux machines. You can even update from one Linux release version to another!
This release includes some bug fixes and small improvements respect to 4.1.4. If you're already using the unstable branch, the update to 4.1.6 is really smooth and it's strongly suggested.
After moved to 4.1.6 it's strongly suggested to update also all your .master scripts for your images (by si_mkautoinstallscript).
This is the changelog from 4.1.4:
- use hotplug to automatically load kernel modules in
autodetect_hardware_and_load_modules() with BOEL
- print a list of loaded kernel modules at the end of
autodetect_hardware_and_load_modules()
- remove spinner when quietly installing image: this removes dirty characters
in the virtual console of si_monitortk
- use a more reliable way to copy module configuration files for UYOK
- removed 94all.update_initrd post-install script: the same feature is
provieded by systemconfigurator adding CONFIGRD = yes in systemconfig.conf
- fixed a bug in disks/partitions auto-detection routine to initialize LVM
devices when --autodetect-disks option is used
- resolve symlinks when copying module configuration files for UYOK (this fixes
disk-by-id naming problems with openSuSE 10.3)
- added a workaround to not touch /dev/null on a build host with old versions
of gcc
- updated BusyBox to 1.9.1
- updated rsync to 3.0.0
- updated mdadm to 2.6.4 (this also fixed a bug with 256K chunk size and RAID5
devices)
- various improvements in si_lsimage (completely rewritten to show images
details in parallel)
- fixed a bug with recent kernels and RAID-4/5/6 modules (now all the
RAID-4/5/6 functions have been merged in the raid456.ko kernel module)
- some optimizations in si_clusterconfig
- now the option --server must be not mandatory for si_prepareclient if
--no-rsyncd is specified

Automating Xen VM deployment with SystemImager
This article focuses on the integration of SystemImager and Xen to create an open source framework able to manage on-demand deployment of virtual machines, such as physical machines, using a single centralized point of management.
SystemImager also helps to automate transitions from physical to virtual, virtual to physical, and/or virtual to virtual envronments (even between different virtual technologies, i.e. VMWare to Xen or vice versa), reducing IT costs, improving business agility and simplifying administrative workloads.

SystemImager 4.1.4 (unstable) released
SystemImager is software which automates Linux installs, software distribution, and production deployment.
SystemImager makes it easy to do automated installs (clones), software distribution, content or data distribution, configuration changes, and operating system updates to your network of Linux machines. You can even update from one Linux release version to another!
This release includes a lot of bug fixes, that means it should be (hopefully) considered nearly a stable release.
The most important news is the introduction of the Xen support. Hopefully soon we'll be able to use SystemImager to provision and manage virtual environments such as physical environment, or to use it as the right tool to perform physical to virtual, virtual to virtual and virtual to physical migrations. All transparently in the same way and using the same tool!
The other important fixes consists in the improved interactions with System Configurator, that allows to have a better support for heterogeneous clients and gives a total independence from images to block device management. This means that now you can easily migrate your clients from a initial block device configuration to another (moving from non-LVM to LVM, or from non-software RAID to software RAID devices, for example), using the same image and only changing the partitioning configuration (autoinstallscript.conf).
After updating to 4.1.4 it's strongly suggested to update all the .master scripts of your images (si_mkautoinstallscript).
This is the changelog from 4.1.2:
- turn on rsync quick checks (based on size and modification timestamp) for files in the image and turn off quick checks for files in the overrides
- allow CTRL+C to break the init script (/etc/init.d/rcS)
- fix disk names in /boot/grub/device.map if it exists in the image
- updated BOEL kernel to 2.6.24.2 (for i386 and x86_64)
- allow si_clusterconfig to show the image associated to each client
- properly detect UYOK kernel version also when the build string contains the the build date in the yyyy/mm/dd format
- fix: automaticaly exclude blkid.tab from images
- allow to auto-detect disks when imaging Xen VMs (experimental)
- fix: correctly skip non-kernel files in UYOK kernel detection
- fix: set correct disk names for systemconfigurator
- any change in autoinstallscript.conf now automatically fixes the boot-loader configuration, so the warning in si_mkautoinstallscript is no more needed, just remove it
- updated rsync to 3.0.0pre10
- print image size on the console before starting imaging
- update the cluster configuration cache only when si_clusterconfig changes something
- do not clean-up si_monitortk threads on exit
- print a note about cluster-register/cluster-map website (http://www.systemimager.org/cluster-register) when a image is successfully cloned and configured by si_getimage
- synchronize /etc/hosts with /var/lib/systemimager/scripts/hosts (the hosts file used during imaging) by si_clusterconfig only when /etc/hosts changes
- remove redundant boot parameters in systemconfig.conf
