No clue from the log , is there anything useful from /var/log/dmesg ? or dmesg

直接就reboot了,看了系统日志前后完全没有提示,很苦恼,看来你们也没碰到过吧

另外,在当时放弃测试后想上线应用,发现用作dpdk的网卡不能正常回包了,表现为主动发往其网关的icmp包能正常返回,同一网段其它主机发给它的包没有返回,抓包看到包确实已经到达此网卡,却没有返回,iptables规则没问题,全清了也一样,uio模块在重启后没有去手动加载,网卡驱动也重置为ixgbe了。
最终无奈重装了系统才恢复,感觉好像编译过程改变了系统内核层的处理,照理不应该呀

我也遇到类似情况,给板载的intel 82599网卡加载igb_uio驱动并且启动dpvs时,会出现整个系统hang住了的情况,屏幕键盘都没有反应,只能重启。但是用安装在PCIE槽的网卡运行则没有问题。可以考虑换个网卡试试?

请问这个问题后来解决了吗?谢谢
from dpvs.
DPDK对网卡的兼容要求确实比较高,因为我们测试和线上环境都是X540网卡,暂时没有其他类型的网卡,也没法复现这样的问题。只好说看看日志或者猜测。另外,也可以去DPDK那边问问,是不是82599有类似的问题。

@okletswin any update ? Or could you pls try other NIC model ?
from dpvs.
@beacer 然后没再测了,我们这边好像都是82599的,回头我也试试X540
from dpvs.
Ok.

这个问题一般是dpdk使用的内核模块(比如rte_kni.ko, igb_uio.ko)的问题,确保它们和使用的DPDK版本匹配,同时不要在正在使用的时候卸载或删除它们。
