• um folder: correspond to /usr/src/linux/arch/um

• uml_switch folder: correspond to /usr/src/dvs/dvs-apps/uml_switch

• dvs_uml_switch folder: correspond to /usr/src/dvs/dvs-apps/dvs_uml_switch

Clone this code:

git clone https://github.com/cotyq/uml-rtuntap.git
cd uml-rtuntap

Create a new branch in uml-rtuntap:

git switch -c update-vm

Mount the VM code in um and uml_switch folders:

sshfs -o nonempty root@192.168.1.2:/usr/src/linux/arch/um um
sshfs -o nonempty root@192.168.1.2:/usr/src/dvs/dvs-apps/uml_switch uml_switch
sshfs -o nonempty root@192.168.1.2:/usr/src/dvs/dvs-apps/dvs_uml_switch dvs_uml_switch

update-vm branch will contain the VM code and master will contain the git repository code.

To see the difference between VM and repo:

git diff --name-status master

Following with the previos section instructions.

In case the VM code is out-of-date:

1. Commit your changes to update-vm branch.

git status
git add ...
git commit

2. Checkout to master branch. Due to um and uml_switch were mounted from VM, checkout changes will be automatically applied in the VM.

git checkout master
