Hello, (please keep me CC'ed, I'm not subscribed) I have a NVMe-like high-performance storage device which requires a proprietary module to work. Because it is not upstream, I tend to distrust by default its quality, and I want to isolate it from the rest of the machine. I did this by using PCI virtualisation, so now I have a qemu-kvm running a kernel with the proprietary module, and containing the block device, and I want to expose this block device back to the host (where the databases desiring to access this block device will run). If I ignore the hypervisor/VM relationship, I would be tempted to setup an iSCSI target over the network, but I am worried about the overhead. But with this special relationship in mind, I would like to use vHost-like, just in the exact opposite way (VM has the backstore, host is the initiator and gets a block device), and likely get a lower overhead. Is this possible ? I am quite new to the whole virtio family, so please forgive me if the answer is blindingly obvious. -- Vincent Pelletier ERP5 - open source ERP/CRM for flexible enterprises
