Can't assign ip address to VM.

[ping4support]

Hi,

We are new to proxmox. We have created test VM but we can't assign ip address from host node bridge. Any one please assist with us.

Our server network configuration files.
===============================================
root@prox-test:~# cat /etc/network/interfaces
auto lo
iface lo inet loopback

#iface enp0s25 inet manual
iface eno1 inet manual
auto vmbr0
iface vmbr0 inet static
address 209.90.xxx.xxx
netmask 255.255.xxx.xxx
gateway 209.90.xxx.xxx
bridge_ports eno1
bridge_stp off
bridge_fd 0
==================================================

We need to assign ip address to VM same subnet from hostnode.
How to assign below ip's to VM's.

209.90.xxx.xxx
209.90.xxx.xxx

Thanks,

You need to configure the Guest IP inside your Guest. There is no need to change the host network configuration.

Hi,

We had tried guest ip also inside VM it's not working. is there need to configure any DHCP.
And also if we have more no of VM's need to configure network individually ? Need to assign ip address automatically when we create VM's in host node. is there any possible?

Thanks,

No, that should work out of the box. Try to use tcpdump (or similar tools) to debug your network.

And also if we have more no of VM's need to configure network individually ?

Yes, unless you use a DHCP server.
