[SailfishDevel] Some issues about developing in the SDK

[David Greaves]

:)

In that case, ssh in as root and paste this:

ln -sf ../vboxservice.service /lib/systemd/system/basic.target.wants/
cat <<EOF >/lib/systemd/system/vboxservice.service
[Unit]
Description=VBoxService daemon for various aspects of guest control

[Service]
Type=simple
ExecStart=/usr/bin/VBoxService -f

[Install]
WantedBy=basic.target
EOF

restarting the VM should bring it up

You can do this on the SDK and emulator.
