一、PVE(Proxmox)提示TASK ERROR: command ‘apt-get update’ failed: exit code 100错误的解决方案

如下图

解决方式：登录PVE web管理界面-服务器视图-数据中心-pve-更新-存储库，将存储库里面的更新全部禁用，你也可以禁用出错的。 

二、错误详见如下与截图

TASK ERROR: start failed: QEMU exited with code 1

我的情况属于直通了GPU，开启虚拟机后就有如上图的错误，原因是我的PVE宿主机内存有16GB，直通的虚拟机也分配了16GB导致的，虚拟机的最大内存=PVE宿主机最大内存-2GB即可。
