Subject: [PATCH] v2v: Add <Disk ovf:capacity> attribute containing disk
 virtual size (RHBZ#1592468).

Virt-v2v transfers to newer versions of ovirt-engine can fail with:

  ovirtsdk4.Error: Fault reason is "Operation Failed". Fault detail is "failed to parse a given ovf configuration ovf error: [empty name]: cannot read '//*/disksection' with value: null". HTTP response code is 400.

This was caused by a change made to oVirt:

  https://gerrit.ovirt.org/#/c/91902/

so that it now requires the <Disk ovf:capacity> attribute.

Thanks: Arik Hadas
