SCSI-attach source VMDKs onto a proxy guest with ReconfigureVM and read them as local SCSI devices, including NVMe/SATA sources remapped onto proxy SCSI. Co-authored-by: Cursor <cursoragent@cursor.com>
The SAN transport can be used when VMFS is stored on an iSCSI lun. Instead of talking to ESXi over NBD/NFC, the data is retrieved from the iSCSI lun directly, which will be temporarily mounted locally. This also means that we need to parse VMDKs residing on VMFS. Normally we'd use vmfs(6)-fuse to mount the filesystem and then parse the VMDK using libqemu. Unfortunately all the vmfs-fuse implementations seem to be abandoned, so we had to implement VMFS and VMDK parsing in OpenVixDiskLib. For this reason, we'll consider this implementation experimental only. FibreChannel is unsupported, we didn't have hardware to test it.
