Folks, A final RC has been tagged in the xen-4.2 branch: http://xenbits.xen.org/hg/staging/xen-4.2-testing.hg (tag ''4.2.0-rc5'') We plan to call the 4.2.0 release on Monday, with no further modifications. So please test this "GA preview"! -- Keir

This patch is incomplete, but early feedback would be welcome. Rich.

This isn't quite the full thing. I think that Pino is also working on replacing the ssh and scp commands in the v2v/input_vmx.ml file with libssh. Without those changes, -i vmx will still issue raw ssh and scp commands, which will use ssh-agent (or keyboard-interactive). The Xen input method doesn't use raw ssh and scp commands, so that one is OK. Rich.

This is a rough-and-ready implementation of nbdinfo --map option, to display the allocation and other metadata of NBD exports. I only tested it lightly against nbdkit. It needs at least some tests. Command like these should work: nbdinfo --map nbd://localhost nbdinfo --map=qemu:dirty-bitmap nbd://localhost Rich.

Setting timezone is easy. It turns out to be almost impossible to set keyboard layout in virt-builder sanely, so I have added some examples instead. Coming up next, setting languages in virt-builder (clue: very very very hard). Rich.

These three patches (for discussion only, NOT to be applied) implement a mutex system that lets the user limit the number of libguestfs instances that can be launched per host. There are two uses that I have identified for this: firstly so we can enable parallel-tests (the default in automake >= 1.13) without blowing up the host. Secondly oVirt has raised concerns about how to limit the
