Re: [libvirt-users] If it's possible for a third-party PCIe card to be shared by multiple containers

Dear Daniel, The thirty-party PCIe card is based on the Xilinx’ FPGA which is off the shelf, the main features are as follows: 1) x8 Gen3, 8Gb/s per lane/direction 2) MSI and legacy interrupt support 3) Scatter-gather packet DMA engine provide by Northwest Logic We hope multiple Linux Containers to access the PCIe card in time division mode, for example, during slot 1, lxc1 read/write the PCIe card; during slot 2, lxc2 read/write the PCIe card. Taking reading operation (data flows from PCIe card to host memory) as example, in native mode, the PCIe driver should tell PCIe card the host memory address where to store the incoming data from PCIe card. With this address, the PCIe card will transmit the data to host memory itself. In container case, the problem is how application running in the container knows the expected host memory address. I wonder if we can have a process running in the which solely operates the PCIe card, all the containers will send/receive data to this process via socket.
