I run Graylog on Hyper V, but there is no network connection, there is message about “failed to connect to lvmetad” ![Annotation%202019-11-10%20104044](https://us1.discourse-cdn.com/flex016/uploads/graylog/original/2X/1/1fae854df033eeb49f931a61c6fdb6914705cc95.png) ---

If you use OVA, this VM by default support obtaining IP address from DHCP. So first check your network interface loging into ubuntu using username: `ubuntu` and password: `ubuntu`. After that check your interface name and ip adress using command: `sudo ip addr show` If you don’t have DHCP in your network, you have to configure IP address manualy using netplat like this: `sudo vim /etc/netplan/01-netcfg.yaml` > network: > version: 2 > renderer: networkd > ethernets: > ens160: > addresses: > - 10.0.0.10/24 > gateway4: 10.0.0.1 > nameservers: > addresses: [10.0.0.1] _Change line ens160: to your real interface name (output of command: sudo ip addr show)_ `sudo netplat apply` Graylog show default web interface password for admin user only first time on console (it’s generated). So if you restart your VM second time, you can’t see it. If so you have 2 options: 1. Either generate your own password and setup it to parameter `root_password_sha2` sudo vim /etc/graylog/server/server.conf [https://docs.graylog.org/en/3.1/pages/configuration/server.conf.html#general](https://docs.graylog.org/en/3.1/pages/configuration/server.conf.html#general) 2. Or remove generated password on parameter `root_password_sha2` so line like will look like this: `root_password_sha2 = `. After that create file /var/lib/graylog-server using command: `sudo touch /var/lib/graylog-server/firstboot` and reboot. After reboot you should see new password on console before login. > sudo vim /etc/graylog/server/server.conf > sudo touch /var/lib/graylog-server/firstboot > sudo reboot ---

Please use this indentation… so either add space to desired lines, or replace with next block ``` network: version: 2 renderer: networkd ethernets: enp0s10f0: addresses: - 192.168.40.62/24 gateway4: 192.168.40.1 nameservers: addresses: [192.168.40.1] ``` ---
