LXC SSH 在 CentOS7 中太慢

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：

...    
debug3: load_hostkeys: loading entries for host "192.168.42.110" from file "/root/.ssh/known_hosts"
    debug3: load_hostkeys: found key type ECDSA in file /root/.ssh/known_hosts:2
    debug3: load_hostkeys: loaded 1 keys
    debug1: Host '192.168.42.110' is known and matches the ECDSA host key.
    debug1: Found key in /root/.ssh/known_hosts:2

    debug2: key: /root/.ssh/id_ecdsa ((nil)),
    debug2: key: /root/.ssh/id_ed25519 ((nil)),

经过很长一段时间才开始使用它：

debug1: Authentications that can continue: publickey,gssapi-keyex,gssapi-with-mic,password
debug3: start over, passed a different list publickey,gssapi-keyex,gssapi-with-mic,password
debug3: preferred publickey,keyboard-interactive,password
debug3: authmethod_lookup publickey
debug3: remaining preferred: keyboard-interactive,password
debug3: authmethod_is_enabled publickey
debug1: Next authentication method: publickey
debug1: Offering RSA public key: /root/.ssh/id_rsa
debug3: send_pubkey_test

我看了看时间 ssh ...命令和尝试时间是

real    5m27.966s
user    0m0.021s
sys 0m0.001s
