Hi,
We are students studying at Carnegie Mellon University, as part of our course project for Operating System Practicum <https://www.cs.cmu.edu/~412/> we wanted to pursue writing virtio block driver support for VirtualBox. We found the below thread in the developer community (forum) which indicates that virtio block support has not been done yet. https://forums.virtualbox.org/viewtopic.php?f=9 <https://forums.virtualbox.org/viewtopic.php?f=9&t=30869&sid=79168a99014f0c7 921f9caa10e898a17&start=15> &t=30869&sid=79168a99014f0c7921f9caa10e898a17&start=15 We checked in the latest source code and found a file VirtioBlk.c in the path src/VBox/Devices/EFI/Firmware/OvmfPkg, which seems to implement EFI BLOCK IO PROTOCOL. Also, there is file VirtioNet.c (in same path) which seems to implement EFI SIMPLE NETWORK PROTOCOL. There is support for backend virtio network driver but no support for backend virtio block driver. We are curious as to why there is still no support for backend virtio block drivers? Is there is any specific reason for the same? Thanks and Regards, Subodh Asthana
