Hi I have a problem with Proxmox network settings, I want to have the host_system behind a vlan. So I followed the manual, but on the initial install, I have a default installation, since I can't set the vlan settings during the initial install.
The host system can be reached under 192.168.0.129, with these settings in /etc/network/interfaces:
auto lo
iface lo inet loopback
iface enp10s0f0np0 inet manual
iface enp5s0 inet manual
iface enp10s0f1np1 inet manual
auto vmbr0
iface vmbr0 inet static
address 192.168.0.129/24
gateway 192.168.0.1
bridge-ports enp10s0f0np0
bridge-stp off
bridge-fd 0
source /etc/network/interfaces.d/*
this works as expected..
Then I change above settings with the ones here below, basically followed the manual, this works fine, without reboot and ifreload -a, now I can reach host on my vlan under 90.1.50.17:
auto lo
iface lo inet loopback
iface enp10s0f0np0 inet manual
iface enp5s0 inet manual
iface enp10s0f1np1 inet manual
auto vmbr0.90
iface vmbr0.90 inet static
address 90.1.50.17/24
gateway 90.1.50.1
auto vmbr0
iface vmbr0 inet manual
bridge-ports enp10s0f0np0
bridge-stp off
bridge-fd 0
bridge-vlan-aware yes
bridge-vids 2-4094
although on the screen where i did ifreload -a, this new address is not shown, still the old 192.168.0.129. So everything seems to work fine, however if I do a restart, I get the first settings back (showing old IP where host can be accessed)?? and I can't access the host anymore, the only way to get out of this is with a reinstall, applying the 2nd settings doesn"t work in this case.
Anyone knows why this happens ?, if my 2nd settings work, forget the original settings, seems to be a case of trying to help the user (restore old settings), but not in this case.
One weird thing, when i look with ip -br a, before the reset,
I see vmbr0 doesn"t have an IPv4 address, but it has a IPv6 address.
vmbr0.90 does have the correct IPv4 address and an IPv6 address, before I do the restart, after restart the interfaces files contains the 2nd settings, but can"t reach the host anymore and the screen shows my host can be found at 192.168.0.129.
A few years ago this was a reason for me to move to XCP-ng, then as well the host seems to easily lose its connection to its host IP which happened a few times, which drived me nuts.
One other thing, this I am doing on a spare server, I have a main server where something like this happens, this server is not reachable anymore, but the vms on it are still running fine and reachable (also on vlans). So before I start molesting the main server, I want to know what is going on and how to really fix it and not within some weeks loose access to this server again.
