Description of problem:

Virt-v2v usually chooses the right amount of RAM and number of vCPUs to assign to the libguestfs appliance during conversion. However the "right" numbers are unknowable in general, and this sometimes causes problems. (eg RHEL-111165).

Virt-v2v 2.9.4 upstream now supports new options --memsize and --smp:

https://github.com/libguestfs/virt-v2v/commit/03b656ed468ecbe309e7cca24721de9369d476aa

We'll add these in RHEL 10.2 (RHEL-111241).

It might be an idea to make these configurable through MTV, at least for advanced users. (Most users should not touch the defaults).
