Note: /download/ directory reorganized

by Richard W.M. Jones

I reorganized the download directory to make it a bit less confusing: http://libguestfs.org/download/ Unfortunately this breaks all previous source URLs: old: http://libguestfs.org/download/libguestfs-1.5.4.tar.gz new: http://libguestfs.org/download/1.5-development/libguestfs-1.5.4.tar.gz Also I'm going to put some binaries in this directory later today, for people not using Fedora who don't want to compile from source: http://libguestfs.org/download/binaries/ Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones New in Fedora 11: Fedora Windows cross-compiler.

[PATCH] Use virtio-serial, remove other vmchannel methods.

by Richard W.M. Jones

Notes: (1) Tis doesn't completely remove legacy serial ports yet. I couldn't work out how to make the Linux kernel see the virtconsole, so that is still using a serial port. (2) The guest network is completely unavailable if you apply this patch. We will need to add this back, possibly as an optional feature.

[PATCH] Change to using ext2-based, cached supermin appliance.

by Richard W.M. Jones

This patch changes libguestfs to use the ext2-based appliance, cached if possible. I've tested this with the alpha version of febootstrap from here: http://koji.fedoraproject.org/koji/buildinfo?buildID=191338 and it at least passes the tests. There are some hacky bits right now: (1) We add the root -drive option last on the command line, then (in the initrd) reverse-search through the block devices, mounting the first one we find. Dan pointed out that we could name the drive using the qemu '-drive file=..,serial=LIBGUESTFSROOT' option, which would allow unambiguous identification. However there are other issues with this. (2) We take steps to ignore the new device from the point of view of the user, but I haven't rigorously gone through the whole API to check that the device is truly hidden everywhere.

Proposed new file apis

by Matthew Booth

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. Matt -- Matthew Booth, RHCA, RHCSS Red Hat Engineering, Virtualisation Team GPG ID: D33C3490 GPG FPR: 3733 612D 2D05 5458 8A8A 1600 3441 EA19 D33C 3490
