Btw. it should work now already, the GNS3 image that Filip linked to in his reply
used the same format, so this seems to be relatively common.

I used the GNS3 one yesterday as test case to integrate some detection quirks, I
also had to accept whitespace in the OVA disk names (we normalize those as standard
PVE volume name through import anyway).

I then also imported A HAOS OVA image, that works in general, but the disk was not
added as boot device, and the disk bus was LSI, I needed to change both to make the
disk available for OVMF. IIRC the OS type was detected "Others" on import, I changed
that, but seems not all defaults changed with it – maybe one could look into that?
HAOS is a common usecase, I alone installed it twice this year, back then I had to
use the qcow2 image and manually import that like a cave man though hehe
