VirtualBox behaves almost the same on different OSes but the default network name for host-only network is different.
The picture below is from Windows. On Linux, it will be named "vboxnet0" by default.
This causes a problem on cross-platform export/import and it's already reported.
VERR_INTERNAL_ERROR: Inexistent host networking interface, named 'vboxnet0'
There are at least 2 workarounds.
VBoxManage.exe modifyvm node1_1 --hostonlyadapter1 "VirtualBox Host-Only Ethernet Adapter"
