Windows 2016 RRAS installation initialization hangs
I came across this while having a similar issue on Nutanix using their Acopolis HV (AHV).
There is no way that I could find to use an emulated Intel driver, so this fix didn't work for me, but it did point me in the right direction, so thank you for that.
The issue was using the Nutanix VirtIO 1.1.1 NetKMV drivers, I installed the latest Fedora VirtIO NetKVM from 0.1.141 and it resolved my issue.
Thanks again for posting this.
