![LXC SSH 在 CentOS7 中太慢](https://linux22.com/image/678965/LXC%20SSH%20%E5%9C%A8%20CentOS7%20%E4%B8%AD%E5%A4%AA%E6%85%A2.png)
我有一个新创建的centos7。我安装了LXC并创建了一个配置:
lxc.network.type = veth
lxc.network.link = lxcbr0
lxc.network.hwaddr = fe:84:8b:f1:76:8e
lxc.network.flags = up
lxc.rootfs = /var/lib/lxc/lon-staging-nginx1.web.com/rootfs
lxc.include = /usr/share/lxc/config/centos.common.conf
lxc.arch = x86_64
lxc.utsname = lon-staging-nginx1.web.com
lxc.network.ipv4 = 192.168.42.110/24
lxc.network.ipv4.gateway = 192.168.42.1
lxc.mount.entry = /root/staging-test vagrant/ none bind 0 0
lxc.mount.entry = /srv/www/cdn srv/www/cdn/ none bind 0 0
lxc.mount.entry = /srv/www/main-application/app srv/www/web/ none bind 0 0
我启动它,并且可以毫无问题地从主机 ping 它。我可以毫无问题地从主机到其他虚拟机进行 SSH。SoftLayer 上的虚拟机和虚拟机之间的 SSH 正在运行。当我想通过 SSH 连接到容器时,我尝试这样做:
ssh -vvvv [email protected]
我尝试过UseDNS 否和GSSAPI身份验证否但这些对我没有帮助。此位置的连接状态:
...

经过很长一段时间才开始使用它:

我看了看时间 ssh ...命令和尝试时间是
