VM shutdown cause entire LAN to freeze

[virtual<3]

I use proxmox 5.0
I have windows 10 VM with following specs:
balloon: 0
bios: ovmf
bootdisk: scsi0
cores: 4
cpu: host,hidden=1
hostpci0: 04:00,x-vga=on,pcie=1,romfile=TI.dump
ide2: local:iso/virtio-win-0.1.126.iso,media=cdrom,size=152204K
machine: q35
memory: 8192
name: TI
net0: virtio=6A:6A:02:0E:EA:04,bridge=vmbr0
numa: 0
ostype: win10
parent: nvidia
scsi0: local-lvm:vm-101-disk-1,size=32G
scsihw: virtio-scsi-pci
smbios1: uuid=35dd7ef6-7db5-4a80-ad0a-3660c6bf5e14
sockets: 1


If I shutdown this vm, my entire network will stop working. I am 100% sure that proxmox is cause to this, because if I unplug my ethernet cable to this specific server instatly everything starts to work. And if I replug ethernet to this server, everything will stop working again.

This sounds to me that you may have some STP blocking traffic. Check your network setup to see if there are links blocked, while the server is unplugged.
