similar to: [PATCH] v2v: -o null: support older qemu-img (RHBZ#1580309)

Instead of writing to a temporary file and deleting it, use the null block driver in qemu to throw it away. --- v2v/output_null.ml | 47 +++++++++++++++++++++++++++++++++-------------- v2v/virt-v2v.pod | 4 ---- 2 files changed, 33 insertions(+), 18 deletions(-) diff --git a/v2v/output_null.ml b/v2v/output_null.ml index d01f45654..4d06aa0de 100644 --- a/v2v/output_null.ml +++

It will be used to do extra checks in the output before copying the disks.

This changes the infrastructure to allow the target_file to be a QEMU URI. Rich.

Add a common debug function for printing debugging messages. It only emits the debug message when the verbose (-v) flag is used on the command line. It sends the output to stderr, which is flushed immediately after the message is printed (to help with debugging unexpected crashes). There are good arguments for sending the debug to either stdout or stderr, and almost all existing debug messages

PROBLEMS: - Target cluster defaults to "Default". - Using Insecure = True, is that bad? - -of qcow2 does not work, with multiple problems - Need to attach disks to VMs somehow This adds a new output mode to virt-v2v. virt-v2v -o rhv-upload streams images directly to an oVirt or RHV >= 4 Data Domain using the oVirt SDK v4. It is more efficient than -o rhv because it does not

Since you have --rhv-cafile mandatory, there is no reason to set Insecure=True. > - -of qcow2 does not work, with multiple problems > - Need to attach disks to VMs somehow

Don't pass these flags to dozens of functions. --- builder/builder.ml | 47 +++++++++-------- builder/cache.ml | 4 +- builder/cache.mli | 2 +- builder/cmdline.ml | 13 ++--- builder/downloader.ml | 14 +++-- builder/downloader.mli

PROBLEMS: - -of qcow2 does not work, with multiple problems * needs to set NBD size to something larger than virtual size - Cannot choose the datacenter. - Not tested against imageio which supports zero/trim/flush.

This way it is possible to override the UUIDs of the uploaded disks, instead of letting RHV generate them. This can be useful to force certain UUIDs, and to specify the disks in --no-copy mode (which now can be used). --- v2v/output_rhv_upload.ml | 43 ++++++++++++++++++++++++++++++++----- v2v/rhv-upload-plugin.py | 2 ++ v2v/virt-v2v-output-rhv.pod | 23 ++++++++++++++++++++ 3 files

It is more efficient than -o rhv because it does not need to go via the Export Storage Domain, and is possible for humans to use unlike -o vdsm. The implementation uses the Python SDK (‘ovirtsdk4’ module). An nbdkit Python 3 plugin translates

All the current output modes use the default, It's just that I have a patch that uses this, so there might be someone in the future who wants to use this and if not, then at least you can tell me if this is wrong or not.

Add a new output mode to virt-v2v: similar to -o local, the written metadata is a JSON file with the majority of the data that virt-v2v knowns about (or collects) during the conversion. This is meant to be used only when no existing output mode is usable, and a guest needs to be converted to run on KVM anyway. The user of this mode is supposed to use all the data in the JSON, as they contain

Create two temporary directories for all the files created during the virt-v2v run: 1) tmpdir, created as $TMPDIR/virt-v2v.XXXXXX, for all the small files 2) cachedir, created as $LIBGUESTFS_CACHEDIR/virt-v2v.XXXXXX, for the big files (e.g. disks) This way there is no need to manually schedule all the temporary files and directories for removal when the application quits. --- v2v/input_ova.ml
