Re: How to connect two VMs running in one system

Hi...
I need some help with this one...
I have installed virtual box in windows XP. Then i set up two virtual machines in that virtual box. Both being fedora 11.
I have manually given the two VMs diff IPs. They are 192.168.1.24 & 192.168.1.22. But as I run the two VMs simultaneously and try 2 ping each of the IPs
it shows destination unreachable. I have set the netmask to 255.255.255.0.
How can I resolve this issue???

What connection mode are you using? NAT, Bridged, Host-only, Internal?
Also look at firewall issues.

Hey thnx 4 taking time & helping out.
Is the connection type an issue??? I am not sure about it. How do I check for that???
I have manually assigned the two VMs diff IPs using the SETUP command in fedora. I can use my http server in both but cant ping each of d 2 VMs.
I have already tried using iptables -F to unblock the firewall in both the VMs.
One more thing the 2 VMs have been installed from same virtual box.
I need some way 2 make these VMs connect each other from my single virtual box.

In the VirtualBox main program where you set it all up, look under the network settings and see what you are using. Report back here.

And please read the manual, chapter 6, to learn more about the network modes.

I just checked the network settings and the two VMs are using NAT.
I changed the settings to Internal Network and tried to ping each of the IPs but it still shows destination unreachable.
Please advice a method so that I can connect the two VMs.

The IP address and netmask are OK. If they are in the same network it should work.

As suggested earlier, firewalls can block ping.

With Internal Networking, the name of the network must be the same. If you want to do another test, you can use Host-Only (only difference with Internal is that this includes the Host in the network).

Well i changed the network settings in virtual box to Host-Only and its working.
