Michael Shigorin	d7689f30c7	tar2vm: rewrote as tar2fs ... Overview of the changes: - ARM support: separate ext2 /boot, no LILO - avoid race condition with devmapper - trap ERR so that -e in shebang doesn't result in extra cleanup hassle - configurable root filesystem type (ext4 by default) - jumps through parted hoops Details: 1. LILO is x86-specific while the rest of the script can be used to prepare e.g. Marvell ArmadaXP or CuBox images; we can generally count on uboot supporting ext2 for relatively sane platforms but not ext4 that would be a better root filesystem performance-wise. 2. Apparently /dev/mapper/loopXpY can be still missing at the time when kpartx returns and pop up a bit later... sit there, wait and check for it. 3. If something went wrong with any command of the script it would bail out due to -e in shebang; it is now better to clean up the loopback device and its mappings in this situation either. 4. One size doesn't fit all, really. 5. The parted sizing was sloppy as in broken, now it's just half insane. Someone's decision to stick units and auto-alignment knobs into a single one was apparently hilarious... http://www.gnu.org/software/parted/manual/parted.html#unit Manual loop/dm cleanup is described in documentation just in case. /boot size meter is suboptimal in terms of additional I/O incurred, will be most likely rewritten to make use of advance "du -s".	2013-06-17 19:29:11 +04:00
Michael Shigorin	5b21100bed	README update ... These have been proofread somewhat to correspond to the current state of affairs; a missing one was added for fonts feature.	2013-06-10 19:43:31 +04:00

Michael Shigorin	eb3df648a2	minor documentation facelift ... A few more items were asking for some attention. In particular, build examples should start with the most basic, error-proof and quick targets.	2012-08-11 22:56:41 +03:00
Michael Shigorin	8a04d9b656	initial specific VM formats support ... Raw disk images are convenient and universal but there are custom formats like Qemu's qcow2 providing additional features, e.g. copy-on-write or space savings. All of this ultimately belongs to mkimage but in the mean time has been implemented here as well.	2012-06-25 19:29:38 +03:00
Michael Shigorin	75f7c62bd1	initial build-vm feature ... Yes, mkimage-profiles is now able to build VM disk images. So far the support is pretty basic: - a single hard drive image with a single partition/FS - only stock root password is configurable - LILO is hardwired as a bootloader The resulting images tend to boot under qemu/kvm though. Please see doc/vm.txt for the warning regarding additional privileges and setup required. This was started back in February but I still hoped to avoid sudo/privileged helper (and libguestfs is almost as undistributable as can be)...
