1. QEMU的vIOMMU将IOVA(I / O虚拟地址)转换为GPA(客户机物理地址)。 2. Qemu的内存管理将GPA(客户物理地址)转换为HVA(qemu进程地址空间内的主机虚拟地址)。 3. Vhost-user库将(QEMU的)HVA转换为自己的HVA。这通常很简单,只需在vhost-user库映射QEMU的内存时将QEMU的HVA添加到mmap返回的地址中即可。 但是如...
Additional networks can be attached to the CNF application using theNetworkAttachmentDefintion resource. TheNetworkAttachmentDefinitionutilizes the host-device CNI plugin to attach vhostuser-based additional interfaces to the CNF application POD. The next section provides a sample definition of theNetworkAtt...
Device plugin cannot directly be used on its own though, since ifindex changes on the launcher-pod's net namespace. So we may (1). create macvtap device, (2). do device plugin + take note of maj:min + (3). mknod(2) on launcher pod. Or directly create macvtap device in the laun...
virtio后端--vhost-user vhost-kernel很类似,不过之前在内核的部分现在有另外一个用户进程代替,可能是snapp或者dpdk等。虽然和vhost-kernel实现的目标一致,但是具体的实现方式却有所不同...。 如果有新的socket连接,说明guest创建了新的virtio-net设备,vhost驱动会为之创建一个vhost设备,之后qemu就可以通过socket和vhos...
