similar to: [FEBOOTSTRAP] Ensure atomic creation of a cached appliance

This patch series adds support for some simple operations on hive files, and I've now tested and verified that those operations work correctly. All except for the last patch (12/12) are ready to be committed. The last patch is WIP.

Couple of notes: (1) You may need to 'make clean' after applying this patch. There is some missing dep so it seems the appliance isn't fully rebuilt. (2) [Comment mainly directed to Matt] This is not a candidate to be automatically added to the stable 1.2 branch. It's far too large of a change for a stable release. Since this change may be required for V2V, please clone

The background to this is that virt-v2v needs to boot the appliance with a specific block device emulation (eg. IDE, not virtio), because when it runs mkinitrd, mkinitrd will assume that the block devices available in the appliance are also the ones which apply at guest boot time. There's no way to override this assumption in mkinitrd (particularly in the old mkinitrd versions that shipped

Cached appliances are discovered by their predictable path. Previously we were creating a cached appliance directly in this predictable path. This had at least 2 undesirable effects: * Interrupting appliance creation would leave a corrupt appliance * 2 processes could simultaneously attempt to create the same appliance, causing corruption. This patch causes the cached appliance to be created

This patch isn't very elegant, but it should be a conservative change that has the least chance of breaking something else.

I think this patch is also uncontroversial. If selinux=1 then we mount /selinux in the appliance. We also bind-mount it into guests when running commands, just like we do for /proc, /dev etc. If SELinux is disabled, then /selinux doesn't get mounted.

This avoids an error where the appliance cannot start up because this dbus helper script (which is never used) is unreadable by non-root. Why do we have unreadable binaries in Fedora at all? You may wonder: https://www.redhat.com/archives/fedora-devel-list/2009-October/msg00987.html Maintaining a blacklist like this is generally a bad thing. We should change this code so it automatically

The Wikipedia pages about schedulers are quite informative. I don't know _why_ this makes a difference, but it does seem to make a small one. Even though for a single process (guestfsd) it would seem that the choice of scheduler should make no difference. BTW the default scheduler in the guest is 'cfq'. http://en.wikipedia.org/wiki/Noop_scheduler http://en.wikipedia.org/wiki/CFQ

One of the things we would really like to be able to do for V2V is to install a new driver in a Windows guest. There are a couple of reasons for this: * The guest may not be bootable without the driver installed, for example because the underlying virtual hardware has changed from vmscsi to virtio. * If the guest can boot, the alternative is to modify the guest to run a script on next boot.

I have continued on with my attempts to get p2v working will little success. I have changed my server to Fedora 16 and finally got an XP with a single SATA disk (sda) to work. I think that this means that the current virt-p2v.iso just doesn't work with the packages that are available on Centos 6 at the moment. However, the machines that I currently need to actually migrate all have

qemu <= 0.10 randomly adds a CD-ROM device to the appliance because of this bit of code: http://git.savannah.gnu.org/cgit/qemu.git/tree/vl.c?h=stable-0.10#n5495 Thankfully this code has been removed from upstream qemu. Anyway I'm not quite sure why we never saw this before - it seems like this code didn't exist in the versions of qemu that were in Fedora, or somehow this code only

I've attached a patch to generator.ml for the proposed new file apis. Note that hread, hpread, hwrite and hpwrite are slightly different to the apis I proposed previously. I've also added hallocate for good measure.
