NTP를 시작할 수 없습니다. [닫기]

지난주에는 잘 작동했지만 이제 virtualbox 내부의 VM이 5분 동안 동기화되지 않습니다.

$ cat /etc/systemd/timesyncd.conf

[Time]
NTP=0.asia.pool.ntp.org,1.asia.pool.ntp.org,2.asia.pool.ntp.org,3.asia.pool.ntp.org
FallbackNTP=0.arch.pool.ntp.org 1.arch.pool.ntp.org 2.arch.pool.ntp.org 3.arch.pool.ntp.org

무엇이 이것의 원인입니까 NTP synchronized: no?
