在虚拟机上一直报错，Cause: Fail to init traffic control: no memory，增大hugepages 也无法解决

[liuzhen111]

请问，在虚拟机上一直报错，Cause: Fail to init traffic control: no memory，增大hugepages 也无法解决，如何解决啊

How many NUMA nodes (sockets) on your VM? If it's only one, pls try to modify DPVS_MAX_SOCKET, other modification may needed.

# lscpu | grep NUMA
NUMA node(s):          2
NUMA node0 CPU(s):     0-9,20-29
NUMA node1 CPU(s):     10-19,30-39

@beacer 感谢了！

lscpu | grep NUMA

NUMA node(s): 1 NUMA node0 CPU(s): 0-7

修改DPVS_MAX_SOCKET=1？ 其余还有哪些需要修改的啊？

同问

[dingtim]

有解决的方法？

[dingtim]

http://dpdk.org/doc/guides/nics/overview.html#id1 虚拟机的网卡，选择列表中支持的。 如果是vmware，网卡选择e1000 ，非vmxnet3。

[mayou33]

dpdk是支持vmware的vmxnet3。 http://www.dpdk.org/doc/guides/nics/vmxnet3.html

I ran dpvs on a single socket VM successfully. You can try the following:

1. set NETIF_MAX_SOCKETS and DPVS_MAX_SOCKET to 1
2. configure only one lcore in /etc/dpvs.conf if NIC not support flow director or single rxq NIC
3. turn off NETIF_PORT_FLAG_*_CSUM_OFFLOAD if NIC not support hw csum offload

我在测试环境运行DPVS也出现“Cause: Fail to init traffic control: no memory”这个错误。 测试环境： VMware Workstation 12 vCPU : 1Socket 1Core vMem : 8G -- 12G vNIC ：2张 e1000 (一张用于管理，一张用于DPDK) Linux Distribution: CentOS 7.3 Kernel: 3.10.0-514.el7.x86_64

DPVS的部署步骤是按照 Quick Start 中的步骤进行安装配置的（由于我的测试环境是一个NUMA节点，所以关于hugepage的步骤变更为：echo 2048 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages）

@beacer 请问一下，DPVS的启动是否有最低内存的要求。或者是否可以通过修改什么配置可以降低DPVS对内存的需求。 由于条件限制，目前只能在虚拟化环境进行安装与测试。万望回复！！！

[beacer]

是不是单ＮＵＭＡ和内存大小没关系，2048可能是太小了，你可以尝试按照　@ywc689 的修改试试．如果你机器的内存很小，可以改一下参数，比如conn_pool_size之类，你可以看看rte_mempool_create调用的地方．

我的环境VMware使用centos7.4，两个网卡e1000,(一张用于管理，一张用于DPDK)，1个socket 4个cpu，8G内存。 配置文件从dpvs.conf.single-nic.sample拷贝后修改如下： [root@localhost dpvs-master]# cat /etc/dpvs.conf !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !

vmxnet3 e1000虚拟网卡均不行 @beacer @ywc689 建议给个虚拟机上跑dpvs的环境配置要求，这样便于个人开发测试，谢谢！

[vslinux]

我用的物理机，2个numa 192G内存，大页分配了100G，DPVS1.9.2没问题，今天升级为1.9.4也报这个错误
