libguestfs, nbdkit and virt-v2v have also worked (upstream)
for years out of the box on aarch64, so there should be no
problem there.

If you're interested in RHV (ie. oVirt downstream on RHEL)
then note we don't build virt-v2v for RHEL on aarch64.

Virt-v2v is not very useful on aarch64 since there is not
(yet) any public VMware version for aarch64, although VMware
do have an internal build and rumoured plans for ESXi on aarch64.
