Hi Amnon,

 

With the risk op repeating myself:

 

 

They are running two VM's on a RHEL 8.10 host.

One VM is running Windows 10 with the main application.

The other VM runs RHEL and has an image capture application.

 

Note: the image captured here is from the silicon/chip, It's for a metrology application.

 

The image capture application can capture up to 3 GB data per sec.

This needs to be moved to the other host.

 

They looked at Virtio-FS but think it can not go beyond 1 GB/sec.

 

The usecase is indeed filesharing between two VM's running on the same RHEL host.

The challenge seems to be the data volume of 3Gb/sec

 

At the moment they tried IVSHMEM with a shared memory, which works.

 

They are under the impression that Virtio-FS can only scale to 1 Gb/s.

Probably things will depend on the application (multi threading)?

 

Ofc I can go back to the customer for some questions, but maybe a short call would answer it all.
