KVM call minutes for 2020-01-14

Hi

This notes are very terse because the discussion was quite technical and I am not familiar with this part of qemu. Feel free to fill this.

- libmuser:
* Take all the complication of implementing the device
* support several transport types?
* mediated devices
* tcp or rdma connection
* VMI vs VMF
* SPDK
* Oracle move from unix socket to muser
* Will we use it over kernel or over userspace?
* For polling we are single process
* How do handle recovery, outside process can have quite a bit of state
- multi-process
* trying to integrate multiuser + muser
* look if their vision is ok with qemu expectations
* one continue with muser kernel module
* other is vfio over unix socket
* preferrence is going vfio over unix socket
this allows all implementations work
- out of tree device
* problematic
* require to link with qemu
* what about dpdk and other external
* other appoarch: vfio with outside device
- vfio over sockets
* who is doing that work?
* felipe prototype it long ago
- best way to get this multiprocess in
* they have worked on this for a long time
* no idea about how to go from there

Later, Juan.
