Description
I had asked this at: https://stackoverflow.com/questions/49268571/how-to-use-9p-virtio-mounts-in-gem5 but it was freaking auto deleted due to inactivity, please don't do that Stack Overflow!!!
I want to mount folders from host without networking on a Linux guest, much as explained for QEMU at: https://superuser.com/questions/628169/how-to-share-a-directory-with-the-host-without-networking-in-qemu
I have tried to apply the patch mentioned at: http://gem5.org/WA-gem5 on top of fbe63074e3a8128bdbe1a5e8f6509c565a3abbd4 to reach this commit.
Then I try to run gem5 ARM with a working setup, and adding the --workload-automation-vio=$(pwd) option.
But then I get the error message:
fatal: system.realview.viopci.vio.socketPath without default or user set value
and gem5 exits.
Are there other options that I have to pass? Why isn't that patch merged upstream?
My full gem5 CLI is:

The Workload Automation tools claims to make it work, but I want to find out the raw command needed to set it up manually.
