[PATCH 0/4] v2v: more control over device types
by Roman Kagan
The decision on which device type to use for disks, network and video
cards on output used to be taken deep inside the converting functions.
This is not always desirable. In particular, there are scenarios when
this decision is made before the convertion takes place. E.g. in
in-place mode, the decisions are taken and the output VM configuration
is created outside of v2v tool.
This patchset adds support for such scenarios. Specifically,
- the input configuration parsers are taught to extract network and
video device models in addition to storage controllers
- the converting functions are taught to take the requested device types
into consideration
- the main routine in in-place mode takes the relevant data from the
input VM and passes it to the converter
The copying mode may eventually also profit from this patchset by taking
command-line options for controlling device types, but this isn't
included here.
Roman Kagan (4):
v2v: collect source network and video adapter types
v2v: introduce requested guestcaps type
v2v: take requested caps into account when converting
v2v: in-place: request caps based on source config

[PATCH 1/2] added ntfscat_i api
by Matteo Cafasso
Adding ntfscat_i command for downloading files based on their inode number.
This allows the dowload of files unaccessible otherwise from a NTFS guest disk image.

[PATCH v2 0/4] v2v: more control over device types
by Roman Kagan
The decision on which device type to use for disks, network and video
cards on output used to be taken deep inside the converting functions.
This is not always desirable. In particular, there are scenarios when
this decision is made before the convertion takes place. E.g. in
in-place mode, the decisions are taken and the output VM configuration
is created outside of v2v tool.
This patchset adds support for such scenarios. Specifically,
- the input configuration parsers are taught to extract network and
video device models in addition to storage controllers
- the converting functions are taught to take the requested device types
into consideration
- the main routine in in-place mode takes the relevant data from the
input VM and passes it to the converter
The copying mode may eventually also profit from this patchset by taking
command-line options for controlling device types, but this isn't
included here.
---
v2:
- add catch-all string-valued variants for source network and video adapter
models
- use match instead of mixing match and if
Roman Kagan (4):
v2v: collect source network and video adapter types
v2v: introduce requested guestcaps type
v2v: take requested caps into account when converting
v2v: in-place: request caps based on source config

I haven't tested this in a while to generalize like that. But last time
tested (which was more than a year ago) Cubietruck, I had to use the
host CPU model for the guests[1]. And I don't have it with me
anymore to test again.

Regarding your timeout, from #libguestfs on Freenode, Rich says:
------
<rwmjones> kashyap: yes, they need to use the libguestfs-test-tool -t
option, basically because 32 bit arm is far too slow to run libguestfs
well (probably also they don't have KVM acceleration enabled in their
kernel)
<rwmjones> http://libguestfs.org/libguestfs-test-tool.1.html#options
<rwmjones> but yeah, they're going to have loads of trouble running
libguestfs on such slow hardware

[PATCH] added ntfscat_i api
by Matteo Cafasso
Adding ntfscat_i command for downloading files based on their inode number.
This allows the dowload of files unaccessible otherwise from a NTFS guest disk image.

Does anyone (*ahem* Rich) already have a yum repo with upstream libguestfs rpms for RHEL/CentOS7?
by Ryan Sawhill
Obviously due to the heavy development, the packages in RHEL7 (even
7.2) lack tons of things. I'm specifically interested in virt-builder
and wondering if there's a preview repo that I'm not aware of. ...?

Displaying mountables in the error output of guestfish etc
by Richard W.M. Jones
Cédric pointed out this problem we have:
$ guestmount -a /var/lib/libvirt/images/sles12sp1-pv.img -m '/dev/sda1:/:subvol=.snapshots/2/snapshot:btrfs' /mnt
libguestfs: error: mount_vfs: /dev/sda1 on / (options: 'subvol=.snapshots/2/snapshot'): mount: mount(2) failed: No such file or directory
guestmount: '/dev/sda1' could not be mounted.
guestmount: Check mount(8) man page to ensure options 'subvol=.snapshots/2/snapshot'
guestmount: are supported by the filesystem that is being mounted.
guestmount: Did you mean to mount one of these filesystems?
guestmount: btrfsvol:/dev/sda1/@ (btrfs)
guestmount: btrfsvol:/dev/sda1/@/.snapshots (btrfs)
guestmount: btrfsvol:/dev/sda1/@/opt (btrfs)
guestmount: btrfsvol:/dev/sda1/@/srv (btrfs)
guestmount: btrfsvol:/dev/sda1/@/tmp (btrfs)
guestmount: btrfsvol:/dev/sda1/@/home (btrfs)
[etc]
The problem here is the strings btrfsvol:... are the internal
"mountable" format, and shouldn't be displayed to end users for a
couple of reasons:
(1) It's not intended that people would "know about" these strings.
You're only compliant with the API if you get a string from an API
like guestfs_list_filesystems and pass it to another API like
guestfs_mount.
(2) These strings aren't actually useful, because you cannot pass them
back to the guestfish/guestmount `-m' option. Instead you have to use
the non-obvious form:
-m /dev/sda1:/:subvol=/@/tmp
How do we solve this? Trickier than it seems.
The first attempt to Cédric tried was to call
guestfs_internal_parse_mountable which conveniently splits the
internal string into a device and a volume. As the name suggests,
that is an internal API. We shouldn't be calling this from our tools,
and in any case it doesn't work unless we define -DGUESTFS_PRIVATE=1
all over the place. So that's a bad idea.
I think probably the way to solve this is with new public APIs for
returning the device and volume name from a mountable. Similar to
guestfs_internal_parse_mountable in fact, but a public API that we
commit to.
char *device = guestfs_mountable_device (g, const char *mountable);
char *volume = guestfs_mountable_volume (g, const char *mountable);
If a mountable doesn't have a (sub-)volume, the second API should
probably return a well-defined errno (ESRCH or ENOENT?).
The code in fish/options.c then just has to:
foreach fs in guestfs_list_filesystems:
device = guestfs_mountable_device fs
volume = guestfs_mountable_volume fs
if guestfs_mountable_volume fs returned well defined errno:
printf "-m %s" device
else
printf "-m %s:/:subvol=%s" device volume
That's my idea anyway ...
Rich.

[PATCH] doc: add info on per-function needed feature

Document which feature, if any, is needed for a function; this should
help users in properly checking feature availability when using certain
functions.
