Hi, Now I am facing the issue on rx. VPP is running on the VM having macvtap with e1000. After forwarding the packets for several minutes, suddenly the rx on this interface is stopped. Looks like there is no error on VPP. I can see a lot of Rx drop on macvtap interface on the host operating system.
When injecting the traffic, VPP can forward the traffic during few minutes but suddenly rx on a given interface is stopped. And rx drop counter on a corresponding macvtap interface on the host operating system is increased. Please advice what I need to check and how I can figure out the root cause. Thanks, Tetsuya === 2022/04/26 18:55:13:129 notice dpdk EAL: Detected lcore 0 as core 0 on socket 0 2022/04/26 18:55:13:129 notice dpdk EAL: Detected lcore 1 as core 0 on socket 0 2022/04/26 18:55:13:129 notice dpdk EAL: Detected lcore 2 as core 0 on socket 0 2022/04/26 18:55:13:129 notice dpdk EAL: Detected lcore 3 as core 0 on socket 0 2022/04/26 18:55:13:129 notice dpdk EAL: Detected lcore 4 as core 0 on socket 0 2022/04/26 18:55:13:129 notice dpdk EAL: Detected lcore 5 as core 0 on socket 0 2022/04/26 18:55:13:129 notice dpdk EAL: Detected lcore 6 as core 0 on socket 0 2022/04/26 18:55:13:129 notice dpdk EAL: Detected lcore 7 as core 0 on socket 0 2022/04/26 18:55:13:129 notice dpdk EAL: Detected lcore 8 as core 0 on socket 0 2022/04/26 18:55:13:129 notice dpdk EAL: Detected lcore 9 as core 0 on socket 0 2022/04/26 18:55:13:129 notice dpdk EAL: Detected lcore 10 as core 0 on socket 0 2022/04/26 18:55:13:129 notice dpdk EAL: Detected lcore 11 as core 0 on socket 0 2022/04/26 18:55:13:129 notice dpdk EAL: Detected lcore 12 as core 0 on socket 0 2022/04/26 18:55:13:129 notice dpdk EAL: Detected lcore 13 as core 0 on socket 0 2022/04/26 18:55:13:129 notice dpdk EAL: Detected lcore 14 as core 0 on socket 0 2022/04/26 18:55:13:129 notice dpdk EAL: Detected lcore 15 as core 0 on socket 0 2022/04/26 18:55:13:129 notice dpdk EAL: Support maximum 256 logical core(s) by configuration. 2022/04/26 18:55:13:129 notice dpdk EAL: Detected 16 lcore(s) 2022/04/26 18:55:13:129 notice dpdk EAL: Detected 1 NUMA nodes 2022/04/26 18:55:13:129 notice dpdk EAL: No shared files mode enabled, IPC will be disabled 2022/04/26 18:55:13:129 notice dpdk EAL: No shared files mode enabled, IPC is disabled 2022/04/26 18:55:13:129 notice dpdk EAL: VFIO PCI modules not loaded 2022/04/26 18:55:13:129 notice dpdk EAL: No shared files mode enabled, IPC is disabled 2022/04/26 18:55:13:129 notice dpdk EAL: Bus fslmc wants IOVA as 'DC' 2022/04/26 18:55:13:129 notice dpdk EAL: PCI driver net_e1000_em for device 0000:00:04.0 wants IOVA as 'PA' 2022/04/26 18:55:13:129 notice dpdk EAL: PCI driver net_e1000_em for device 0000:00:05.0 wants IOVA as 'PA' 2022/04/26 18:55:13:129 notice dpdk EAL: PCI driver net_e1000_em for device 0000:00:06.0 wants IOVA as 'PA' 2022/04/26 18:55:13:129 notice dpdk EAL: Bus pci wants IOVA as 'PA' 2022/04/26 18:55:13:129 notice dpdk EAL: Selected IOVA mode 'PA' 2022/04/26 18:55:13:129 notice dpdk EAL: Probing VFIO support... 2022/04/26 18:55:13:129 notice dpdk EAL: IOMMU type 1 (Type 1) is supported 2022/04/26 18:55:13:129 notice dpdk EAL: IOMMU type 7 (sPAPR) is not supported 2022/04/26 18:55:13:129 notice dpdk EAL: IOMMU type 8 (No-IOMMU) is not supported 2022/04/26 18:55:13:129 notice dpdk EAL: VFIO support initialized 2022/04/26 18:55:13:129 notice dpdk EAL: Ask a virtual area of 0x2e000 bytes 2022/04/26 18:55:13:129 notice dpdk EAL: Virtual area found at 0x100000000 (size = 0x2e000) 2022/04/26 18:55:13:129 notice dpdk EAL: Setting up physically contiguous memory... 2022/04/26 18:55:13:129 notice dpdk EAL: Setting maximum number of open files to 4096 2022/04/26 18:55:13:129 notice dpdk EAL: Detected memory type: socket_id:0 hugepage_sz:2097152 2022/04/26 18:55:13:129 notice dpdk EAL: Creating 4 segment lists: n_segs:8192 socket_id:0 hugepage_sz:2097152 2022/04/26 18:55:13:129 notice dpdk EAL: Ask a virtual area of 0x61000 bytes 2022/04/26 18:55:13:129 notice dpdk EAL: Virtual area found at 0x10002e000 (size = 0x61000) 2022/04/26 18:55:13:129 notice dpdk EAL: Memseg list allocated at socket 0, page size 0x800kB 2022/04/26 18:55:13:129 notice dpdk EAL: Ask a virtual area of 0x400000000 bytes 2022/04/26 18:55:13:129 notice dpdk EAL: WARNING!
