[nbdkit PATCH 0/3] Add nozero filter
by Eric Blake
I still need to add testsuite coverage. Perhaps it might be easier
if I create a new '--filter=log logfile=foo' filter that produces
a log of which commands a client sent, then compare the log using
a known client that uses write_zeroes (qemu-io works well) both
with and without --filter=nozero to prove that the change in
advertisement changes the commands sent over the wire (that would
also test the log filter at the same time...).
I'll wait for a review on this series, particularly since patch 2
intentionally breaks filter ABI (more ABI/API breaks on the way
when I resubmit my FUA work; it would be nice to make all the API
breaks before v1.1.29, rather than releasing versions while things
are still in flux).
Note that even if we try hard to let newer nbdkit load an older
filter (which I did not do here), we absolutely cannot let older
nbdkit load a newer filter - while we have sizing limits to
guarantee we don't call beyond the end of an older filter's
smaller struct, there are no sizing limits in the other
direction to prevent a newer filter to know that it cannot call
beyond the end of our smaller nbdkit_next_ops.

[nbdkit PATCH] maint: Improve ./nbdkit handling of --opt=value
by Eric Blake
Although useful for in-tree debugging, the ./nbdkit script was not
very nice when it comes to using the '--longopt=value' single-string
form of options, compared to the two-string '--longopt value' form.
Since we used a glob for the multiple spellings of --exportname and
--pidfile, the script would try to treat the next argument literally
instead of recognizing that the argument was already consumed.
Likewise, the script was not recognizing '--filter=foo'.
Since the script already relies on bash, we can exploit bash's
case fallthrough (using ';&' instead of ';;'), to rewrite inline
--filter=foo without having to duplicate logic.
This does NOT try to honor option abbreviations. If you are testing
that aspect of getopt_long, don't use this script ;)

[PATCH nbdkit] Change the default protocol to newstyle.
by Richard W.M. Jones
nbdkit <= 1.1.28 defaulted to the oldstyle protocol for compatibility
with qemu and libguestfs. However qemu >= 2.6 can now work with
either protocol and is widely installed. Also newstyle is required
for newer features such as export names and TLS. In addition
nbd-client dropped support for oldstyle entirely.
You can select the oldstyle protocol by adding ‘-o’, and it is still
tested.

[RFC] Inconsistent output of guestfs_list_filesystems
by Mykola Ivanets
Before I rush to change something I request your comments on the subject.
Let me know what do you think and if it does make sense.
The issue: guesfs_list_filesystems is inconsistent in its output.
For, example, it filters out partitioned physical devices but doesn't do the same for MD devices.
More over, according to its name and API documentation guestfs_list_filesystem should return something
which potentially can be mounted (SWAP is an exclusion and it is stated in API doc).
It is the reason partitioned physical devices are filtered out:
they are not mountable even in theory (they don't contain filesystem if they contain partition(s)).
Another example of non-mountable block device is extended MSDOS partition.
Also nothing stops you from creating partition table and partitions on logical volume
(yes, it is probably uncommon but nevertheless). In this case such partitions are ignored completely.
Yet another example is Windows dynamic disks aka LDM: guestfs_list_filesystems returns both
ldm_vol_ and ldm_part_ but strongly speaking only volumes should be considered as mountables.
And last example is again with Windows dynamic disks and their physical counterparts:
guestfs_list_filesystems filters out disks with MBR type byte 0x42 but what about GPT?
Patch #1 will add one more test to demonstrate one of the issues described above (partitioned MD device).
Patch #2 will define function which tells if device is partitioned (yes, it doesn't work with dm-devices).
Patch #3 fixes the issue with partitioned MD devices.
At the moment don't pay too much attention at the code itself - it is just a quick way to demonstrate the issue.

Trying to mount vmdk - kernel panic not syncing: Attempted to kill init! exitcode=0x00000100
by James Cook
Hallo
I'm trying to mount individual vmdks from a crashed Esxi server (the HDD
is suffering sector failures).
Using a rescue system I can mount the Esxi with vmfs-fuse.
I copied the files across to a data rescue machine and here guestmount
did work for all but one vmdk - even though the VMs were not necessarily
shutdown gently.
I changed the vmfuse version on the rescue system - with which I'm
accessing the "crashed" server's data (the HDD).
Then the original data rescue machine was deleted by accident. So I've
created a new data rescue machine, and I've copied the vms/vmdk files
from the original server to this new data rescue system.
The only problem is that I now can't get guestmount to work on the vmdks
(as it did before) :(
The reasons could be:
1. further data degradation on the original server - but rsync reported
no errors
2. the new vmfs-fuse doesn't mount vmdk files correctly so copying you
don't get the real thing - again rsync (at file level) reported no
errors
3. the environment in which I am now calling guestmount is somehow
different.
