Hetzner Additional IPs Config HELP!

edit: i got software raid, i did wrong

mount what? there is no mount in n e t w o r k ... 🤣

or do you mean in rescue? depending on your setup (sw-raid obviously) you need to mount /dev/mdX rather than a single partition that's only part of the raid-array.

cat /proc/mdstat

might give a clue.

you really should try to learn and understand what you are doing first. if you are just looking at random howtos or for readymade solutions you'll never be able to fix things if something breaks.

what do you want to achieve anyway? you know that you will need the main IP still for the hypervisor and the addon IP for the guest. so you still are stuck with one machine - why virtualize then at all?

NAT of course is a way for more machines, but hell, that's going to be a long way to learn 😆

btw: you don't/shouldn't need to define eth0, ens2p0 or whatever the device is called in /etc/network/interfaces, I usually leave it in there set to manual and give no further details. then you define the bridge and bridge it to the device. for a bridged setup that's it.

a full /etc/network/interfaces could look something like this:

source /etc/network/interfaces.d/*

auto lo
iface lo inet loopback
iface lo inet6 loopback

iface enp2s0 inet manual

# default bridge
auto vmbr0
iface vmbr0 inet static
  address 148.123.45.67
  netmask 255.255.255.255
  pointopoint 148.123.45.1
  gateway 148.123.45.1
  bridge_ports enp2s0
  bridge_stp off
  bridge_fd 1
  bridge_hello 2
  bridge_maxage 12

iface vmbr0 inet6 static
  address 2a01:123:456:789::1
  netmask 64
  gateway fe80::1

THANK YOU!!!
Now, i am going to install a virtual machine (debian for example) and write Virutal MAC in that network config? right?

you want to put the virtual mac in the appropriate field in the proxmox control panel while setting up the guest, yes ;-)

PS: debian for the guest is a good start to try, as the interfaces file is easier to setup (in my opinion) - just be aware that the netinst/iso usually don't get network connection during the install with that kind of setup, so you need to go for a very minimal install and edit it in proxmox VNC console after the VM is up and running.

@Falzo
(this has nothing to networking to do but) when I VNC it refreshes every second xD

xlucasonepvp

is it able to fix that?

Falzo

no idea, probably a browser-related issue? which browser and extensions are you using?

you're welcome ;-)

for centos+virt-manager it more or less will be the same, I just can't be bothered to look into the network config files for that. debian. thx.

do you know how to remove a vm?

Falzo

sure. stop the VM and then select more/remove from upper right corner in the panel:
