Hello there.
I had the following network configuration:
/etc/network/interfaces
# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage parts of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!

Everything is ok.
I've had created a Linux VM with this configuration in the network:
net0: virtio=2A:34:29:A5:15:23,bridge=vmbr0,firewall=1,tag=942
So I've had tag the vm network to 942.
My issue is when I started the VM, all of the sudden, it's appears a unknown VLAN, and this make my server goes down, completely!
As you can see in the image.
That's a bit of a mistery to me and I don't know how to solve it.
I have another servers in other DC with same configuration and everything is ok!
I hope somebody can help me!
Thanks.
