有個guest在備分時偶爾會出現以下的錯誤
怪的狀況不是每天
而是不定時會發生

查了一下forum有人碰到相同的情況

是建議修改

/usr/share/perl5/PVE/QMPClient.pm 

in line 134

      } else {

            $timeout = 3; # default

to

      } else {

            $timeout = 8; # default

我直接把 $timeout改為30

restarted the pve daemons

for service in pvedaemon.service pveproxy.service pvestatd.service ;do

     echo "systemctl restart $service"

     systemctl restart $service

  done

目前就先醬改了

再觀察看看
