List smb shares (eg debugging)
smbclient -NL //10.0.2.2
## Shared host directory via NFS
For debian HOST install 'nfs-kernel-system', then:
vim /etc/exports
Example: "/path/to/share 127.0.0.1(rw,no_subtree_check,insecure)"
exportfs -a; /etc/init.d/nfs-kernel-server restart
For windoof HOST install WinNFSd, then:
WinNFSd.exe -addr 127.0.0.1 C:\path\to\share /path/to/share
In GUEST to access it do:
$SUDO apt install -y --no-install-recommends nfs-common
apk add rpcbind && /etc/init.d/rpcbind start
mkdir /mnt/host
$SUDO mount -t nfs -o vers=3 10.0.2.2:/path/to/share /mnt/host
Keep build result inside vm:
mkdir /tmp/build /mnt/host/build
mount --bind /tmp/build /mnt/host/build
## USB pass-through
NOTE: Couldn't yet test any of those commands.
### By physical port
-usb -device usb-host,hostbus=1,hostport=2
### By physical port via hub
-usb -device usb-host,hostbus=1,hostport=2.3
### By device
-usb -device usb-host,vendorid=123,productid=456
