I can’t assign an IP address to vmware VM from DHCP pool

In GNS3, I have configured the DHCP pool on the router R1, and I have a vmware VM (Ubuntu 16.04), another router R2 and VPCs are connected to R1. The R2 and VPC can get their IP address without a problem, however, the vmwareVM can’t receive the IP address.

Note that:

• the station is configured as host-only
• the connect a host virtual adapter to this network is checked
• the VMware Workstation DHCP Server is turned OFF
• No configuration on my local PC Network Connections (DHCP)

Once I type the command dhclient eth0 to get the IP address from dhcp, it freezes and returns nothing and no IP address is assigned.

I want to know what is the problem that causes that issue and how to solve it.

Thank you.
