[Libguestfs] [PATCH v2v] -o rhv-upload: Give a nicer error if the storage domain

https://bugzilla.redhat.com/show_bug.cgi?id=1986386 My RHV instance is dead at the moment so I didn't do much more than check this compiles and passes the one test we have. Also I want to spend as little time as possible on RHV outputs for virt-v2v since the RHV product will be discontinued soon. I did want to point out some things: - The preceeding code is probably wrong. https://github.com/libguestfs/virt-v2v/blob/master/output/rhv-upload-tran... It attempts to search for the output storage using: storage_domains = system_service.storage_domains_service().list( search='name=%s' % params['output_storage'], case_sensitive=True, ) I couldn't find any documentation about what can go into that search string, but it's clearly a lot more complicated than just pasting in the literal name after "name=". At the very least, spaces are not permitted, see: https://github.com/libguestfs/virt-v2v/blob/master/output/rhv-upload-tran... - The bug reporter used "data*" as the name and I suspect that is parsed in some way (wildcard? regexp? I've no idea). - Probably for the same reason, the preceeding code ought to fail with an error if the output storage domain doesn't exist. The fact we reach the code patched here at all also indicates some bug, maybe in the search string. As I say above, I don't especially care about any of this. Rich.
