[PATCH 0/4] v2v: more control over device types
by Roman Kagan 25 Mar '16

25 Mar '16

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 test-data/phony-guests/guests.xml.in | 8 +++ v2v/convert_linux.ml | 49 +++++++++++---- v2v/convert_windows.ml | 4 +- v2v/input_disk.ml | 2 + v2v/input_libvirtxml.ml | 32 ++++++++++ v2v/input_ova.ml | 2 + v2v/modules_list.ml | 3 +- v2v/modules_list.mli | 3 +- v2v/test-v2v-i-ova-formats.expected | 1 + v2v/test-v2v-i-ova-gz.expected | 1 + v2v/test-v2v-i-ova-two-disks.expected | 1 + v2v/test-v2v-print-source.sh | 4 +- v2v/types.ml | 73 +++++++++++++++++++---- v2v/types.mli | 17 +++++- v2v/v2v.ml | 58 +++++++++++++++++- v2v/windows_virtio.ml | 108 ++++++++++++++++++++++++---------- v2v/windows_virtio.mli | 8 ++- 17 files changed, 309 insertions(+), 65 deletions(-) -- 2.5.0

[PATCH v2 0/4] v2v: more control over device types
by Roman Kagan 29 Feb '16

29 Feb '16

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 test-data/phony-guests/guests.xml.in | 8 ++++ v2v/convert_linux.ml | 49 ++++++++++++++----- v2v/convert_windows.ml | 4 +- v2v/input_disk.ml | 2 + v2v/input_libvirtxml.ml | 27 +++++++++++ v2v/input_ova.ml | 2 + v2v/modules_list.ml | 3 +- v2v/modules_list.mli | 3 +- v2v/test-v2v-i-ova-formats.expected | 1 + v2v/test-v2v-i-ova-gz.expected | 1 + v2v/test-v2v-i-ova-two-disks.expected | 1 + v2v/test-v2v-print-source.sh | 4 +- v2v/types.ml | 77 +++++++++++++++++++++++++----- v2v/types.mli | 19 +++++++- v2v/v2v.ml | 58 +++++++++++++++++++++-- v2v/windows_virtio.ml | 89 ++++++++++++++++++++++++++--------- v2v/windows_virtio.mli | 6 +++ 17 files changed, 298 insertions(+), 56 deletions(-) -- 2.5.0

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.

Does anyone (*ahem* Rich) already have a yum repo with upstream libguestfs rpms for RHEL/CentOS7?
by Ryan Sawhill 26 Feb '16

26 Feb '16

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 26 Feb '16

26 Feb '16

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 ...
