更新:切换到使用网络virtio驱动程序似乎已经修复它。
我试图通过scp将文件从虚拟机复制到远程主机。
经过大量的努力,我发现如果我使用一个Ubuntu云映像,scp命令会在这个状态中停留大约一分钟左右:
ubuntu@ubuntu:~$ scp -i foo.pem logo-60263262.mp4 ubuntu@target.example.com:.
logo-60263262.mp4 0% 0 0.0KB/s --:-- ETA在突然完成转移之前:
ubuntu@ubuntu:~$ scp -i foo.pem logo-60263262.mp4 ubuntu@target.example.com:.
logo-60263262.mp4 100% 645KB 6.9KB/s 01:33注意上面的传送花了1分33秒。
而在Centos云映像上,传输时间为2秒:
[centos@localhost ~]$ scp -i foo.pem logo-60263262.mp4 ubuntu@target.example.com:.
logo-60263262.mp4 100% 645KB 322.3KB/s 00:02我没有办法诊断这两个系统之间的不同之处,而这正是Ubuntu上的问题所在。
有人能建议我能做些什么吗?这是Centos 7和Ubuntu 19的最新版本,我也试用了Ubuntu 18

查看ifconfig输出,在Ubuntu上检测到冲突。
