virt-v2v: Virtio-Scsi patch
by Jean-Louis Dupond
Hi,
I was trying to migrate some VM's to Virtio-SCSI block devices, as this
gives some advantages.
While checking the virt-v2v code, I found out that it supported
Virtio-SCSI, but some bits were missing.
In attachment a small patch that adds the missing bits :)
Best regards
Jean-Louis

[PATCH common v2 0/4] Windows BitLocker support.
by Richard W.M. Jones
For links to the original patch series, see:
https://bugzilla.redhat.com/show_bug.cgi?id=1808977#c8
The original feedback was that ignoring errors from guestfs_luks_uuid
would ignore legitimate errors from non-BitLocker disks, so I have
modified this series so that errors are only ignored in the BitLocker
case. As noted in the 4th patch there is no actual error in the
BitLocker case, cryptsetup luksUUID simply exits without printing
anything.
Rich.

[libnbd PATCH 0/3] opt_list_meta_context
by Eric Blake
I'm posting this now, as I'm at the end of a workday and I got things
working for manual experimentation.
Still to do:
- write interop tests for qemu-nbd and nbdkit (including my proposed
patch addition of qemu-nbd -A to show qemu:allocation-depth)
- figure out if we can make 'nbdinfo --map' use the new API to
automatically select all contexts advertised by the server
Eric Blake (3):
api: Add get_nr_meta_contexts, clear_meta_contexts
generator: Rename OPT_SET_META_CONTEXT states
api: Add nbd_opt_list_meta_context

[nbdkit PATCH] server: Adjust limit on max NBD_OPT_* from client
by Eric Blake
Up to nbdkit 1.22, we never advertised large export lists, so a client
had no real reason to give more than 32 NBD_OPT_ commands before
finally selecting an export or quitting, and we were justified in
dropping indecisive chatty clients as being a waste of server
resources. But now that we support .list_exports, it is reasonable
for a client (such as 'qemu-nbd --list' or 'nbdinfo --list') to want
to call NBD_OPT_INFO and several NBD_OPT_LIST_META_CONTEXT commands
for every export returned in NBD_OPT_LIST. We still want to avoid
clients that can tie us up in eternal handshaking, so let's reject a
second call to NBD_OPT_LIST; but once the first call is made, the
client now has a chance to get info on everything listed.

[libnbd PATCH] nbdsh: Add --opt-mode command line option
by Eric Blake
Similar to --base-allocation, this is a common enough configuration
that cannot be performed with -c when using --uri, but which makes
life easier in scripting. And like --base-allocation, I'm starting
with only a long option spelling, rather than burning a short option
letter.
