I have a virtual machine which I launch using following code. 

kvm -m 2G -hda image.raw -hdb image.data.qcow2 -redir tcp:11180::80

How can I transfer files from a Linux host to the virtual machine?

You can transfer files using SCP protocol working on the same port as SSH. For that you need to redirect the port 22 on the virtual machine to a local port (2222 in this example):

kvm -m 2G -hda image.raw -hdb image.data.qcow2 -redir tcp:11180::80 -redir tcp:2222::22

and connect with ssh to that port:

ssh -p 2222 user@localhost

To transfer files you can then use scp:

scp -p 2222 file.txt user@localhost:file.txt

  • @ankitkumar How can I know? You need to provide the correct password to your virtual machine.

  • If you're automating this while at the same time increasing security, you can also turn on Public Key Authentication instead of password authentication.
