CPU 版本型号不同，dpvs新版本不能使用。

[dabinDong]

你好，最近在使用dpvs的snat的功能，发现当服务器使用比较老的cpu时候，dpvs功能不能使用，具体问题如下：安装并启动最新版本的dpvs时，只有cpu0的使用率是100%，其他cpu的利用率是0%，dpvs只能启动，dpip和ipvsadm命令不能使用。

cpu版本为： Intel(R) Xeon(R) CPU E5-2630 0 @ 2.30GHz dpvs 版本为： b7331879af18792ae9cc6caf85185eb4d6f342b8 Wed Feb 28 10:44:59

麻烦帮忙看下吧，感谢。

配置文件完全一样么？　有么有更多的Ｌｏｇ信息？

你好，配置文件是完全一样的，配置文件使用了9个cpu， 运行也不报错，但是dpip 命令不能用一直卡在哪里了， 下面是我运行的结果：

我是用top看，只有cpu0是100%的，其他cpu都没使用： top - 12:04:29 up 23:13, 2 users, load average: 1.21, 0.79, 0.41 Tasks: 254 total, 2 running, 252 sleeping, 0 stopped, 0 zombie %Cpu0 :100.0 us, 0.0 sy, 0.0 ni, 0.0 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st %Cpu1 : 0.0 us, 0.0 sy, 0.0 ni,100.0 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st %Cpu2 : 0.0 us, 0.0 sy, 0.0 ni,100.0 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st %Cpu3 : 0.3 us, 0.3 sy, 0.0 ni, 99.3 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st %Cpu4 : 0.0 us, 0.0 sy, 0.0 ni,100.0 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st %Cpu5 : 0.0 us, 0.0 sy, 0.0 ni,100.0 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st %Cpu6 : 0.0 us, 0.0 sy, 0.0 ni,100.0 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st %Cpu7 : 0.0 us, 0.3 sy, 0.0 ni, 99.7 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st %Cpu8 : 0.0 us, 0.3 sy, 0.0 ni, 99.7 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st %Cpu9 : 0.0 us, 0.0 sy, 0.0 ni,100.0 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st %Cpu10 : 0.0 us, 0.3 sy, 0.0 ni, 99.7 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st %Cpu11 : 0.0 us, 0.3 sy, 0.0 ni, 99.7 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st KiB Mem : 65816716 total, 22270932 free, 34084088 used, 9461696 buff/cache KiB Swap: 33030140 total, 33030140 free, 0 used. 31071668 avail Mem

dpip命令： [root@nat /home/xxx/dpvs/bin]# ./dpip addr add 218.23.44.22/32 dev dpdk0 sapool 一直不动。

dpvs log是没有变化的： [root@nat /data/dpvs]# tail -f dpvs.log Mar 12 11:58:31 NETIF: worker cpu6:dpdk1 rx_queue_id += 5 Mar 12 11:58:31 NETIF: worker cpu6:dpdk1 tx_queue_id += 5 Mar 12 11:58:31 NETIF: worker cpu7:dpdk0 rx_queue_id += 6 Mar 12 11:58:31 NETIF: worker cpu7:dpdk0 tx_queue_id += 6 Mar 12 11:58:31 NETIF: worker cpu7:dpdk1 rx_queue_id += 6 Mar 12 11:58:31 NETIF: worker cpu7:dpdk1 tx_queue_id += 6 Mar 12 11:58:31 NETIF: worker cpu8:dpdk0 rx_queue_id += 7 Mar 12 11:58:31 NETIF: worker cpu8:dpdk0 tx_queue_id += 7 Mar 12 11:58:31 NETIF: worker cpu8:dpdk1 rx_queue_id += 7 Mar 12 11:58:31 NETIF: worker cpu8:dpdk1 tx_queue_id += 7

把配置文件的"log_level WARNING"改为"log_level DEBUG"后重试下，看看有没有更具体的log
