Approach
1. As we are using the cloud image from vagrant, the kernel contains the minimal dependencies, therefore, some modules required are missing.
I will append the linux-generic to the provision.sh to ensure the modules uio and uio_pci_generic are corrected configured.
Result: The following two lines are removed from the error log this time

2. In order to deal with the virtual memory allocation, I would like to simply increase the memory assigned without setup for swap space
I will be increasing the memory allocated for the vagrant from vb.memory = 2048 to vb.memory = 4096

Conclusion
It is due to the missing modules in the cloud image and the insufficient memory allocated for the vagrant.
