ubuntu – 允许NTP自动大量更新？

这是我的场景：我在工作站上运行多个VM来模拟生产环境.在一天结束时,我在下午6点睡觉我的工作站(我的VM在后台运行).当我第二天早上8点回到办公室并唤醒工作站时,我的所有虚拟机都在下午6点.

厌倦了重置NTP或只是想记住强制更新,我将以下内容放在5分钟的cron中

服务ntp stop&& ntpd -gq&&服务ntp开始

这是我的/etc/ntp.conf

tinker panic 0

driftfile /var/lib/ntp/ntp.drift

logfile /var/log/ntpd.log

# Enable this if you want statistics to be logged.
#statsdir /var/log/ntpstats/

statistics loopstats peerstats clockstats
filegen loopstats file loopstats type day enable
filegen peerstats file peerstats type day enable
filegen clockstats file clockstats type day enable

# Specify one or more NTP servers.

# Use servers from the NTP Pool Project. Approved by Ubuntu Technical Board
# on 2011-02-08 (LP: #104525). See http://www.pool.ntp.org/join.html for
# more information.
server 0.ubuntu.pool.ntp.org
server 1.ubuntu.pool.ntp.org
server 2.ubuntu.pool.ntp.org
server 3.ubuntu.pool.ntp.org

# Use Ubuntu's ntp server as a fallback.
server ntp.ubuntu.com

# Access control configuration; see /usr/share/doc/ntp-doc/html/accopt.html for
# details.  The web page <http://support.ntp.org/bin/view/Support/AccessRestrictions>
# might also be helpful.
# 
# Note that "restrict" applies to both servers and clients,so a configuration
# that might be intended to block requests from certain clients Could also end
# up blocking replies from your own upstream servers.

# By default,exchange time with everybody,but don't allow configuration.
restrict -4 default kod notrap nomodify nopeer noquery
restrict -6 default kod notrap nomodify nopeer noquery

# Local users may interrogate the ntp server more closely.
restrict 127.0.0.1
restrict ::1

# Clients from this (example!) subnet have unlimited access,but only if
# cryptographically authenticated.
#restrict 192.168.123.0 mask 255.255.255.0 notrust


# If you want to provide time to your local subnet,change the next line.
# (Again,the address is an example only.)
#broadcast 192.168.123.255

# If you want to listen to time broadcasts on your local subnet,de-comment the
# next lines.  Please do this only if you trust everybody on the network!
#disable auth
#broadcastclient

有没有更好的方法来实现这一目标？

如果您使用的是VMware Workstation(或VMware vSphere),则有 specific ways to handle timekeeping on your (Linux) virtual machines.但是,这对于您的睡眠情况来说还不够.仅限来宾的NTP在这里没有帮助.

您绝对需要在来宾虚拟机上安装VMware来宾工具,并确保在主机上运行NTP.这将解决睡眠问题和客人被暂停时发生的漂移.

编辑：

哦,这是Ubuntu …我发现很多Ubuntu用户都没有安装本机VMware工具套件. Here are the steps(以及一个视频)来实现这一目标.
