原因
e1000驱动问题，见：https://forum.proxmox.com/threads/e1000-driver-hang.58284/
解决方案（据说会影响性能）：
vim /etc/network/interfaces
在iface vmbr0 inet static的最后加入 post-up ethtool -K eno1 tso off gso off，例如：
auto lo
iface lo inet loopback
iface eno1 inet manual
auto vmbr0
iface vmbr0 inet static
address 192.168.1.117
gateway 192.168.1.1
bridge-ports eno1
bridge-stp off
bridge-fd 0
post-up ethtool -K eno1 tso off gso off
然后:wq 保存并退出
