[Libguestfs] [PATCH 1/3] v2v: tests: check generated OVF
Check the generated OVF for -o rhv and -o vdsm outputs. Variable UUIDs and date/times are filtered out. Make sure the the important UUIDs (disk, volume, VM) are where we think they should be.

[Libguestfs] [PATCH 2/3] v2v: ovf: Create OVF more aligned with the standard
For historical reasons the OVF used in RHV export domain contains some deviations from the OVF standard. The format used in -o rhv has to remain fixed but for -o vdsm and we could produce much nicer OVF. This patch serves as a preparatory step to this. The main reason for creating different OVF is that it can be used to create VM by oVirt REST API. The RHV export domain flavor cannot be used that way. For now the virt-v2v behavior is unchanged. The modified output will be enabled in some later patch.

[Libguestfs] [PATCH 3/3] v2v: vdsm: add --vdsm-fixed-ovf option
Add option for -o vdsm that enables output of the modified OVF. oVirt engine should already be able to consume the OVF, but let's not take any chances and enable it only by command line argument. It can be made default later when it receives proper testing.

TBH I'd use something a bit more descriptive such as a variant: type ovf_flavour | RHVExportStorageDomain | OVFStandard and then code like this becomes:> + if rhv_export_flavor then > + e "Section" ["xsi:type", "ovf:NetworkSection_Type"] [ > + e "Info" [] [PCData "List of networks"] > + ] > + else > + e "NetworkSection" [] [ > + e "Info" [] [PCData "List of networks"] > + ];(match ovf_flavour with | RHVExportStorageDomain -> ... | OVFStandard -> ... ) Note the parentheses around match which are required.
