Unable to network two virtual machines together

Hello,

I'm having a lot of trouble trying to network two virtual machines for a test environment. Here is some background.

I have two virtual machines, both are configured with host-only networking within Parallels. Both are also configured with manual IP addresses.

Windows Sever 2008 R2
IP: 10.0.0.11
SUBNET:255.255.255.0
Gateway: 10.0.0.1
DNS: 10.0.0.11

Windows XP SP3
IP: 10.0.0.21
SUBNET: 255.255.255.0
Gateway: 10.0.0.1
DNS: 10.0.0.11

I am unable to ping or have the two vm's communicate in anyway. In concerns with pinging. I have turned off the XP firewall all together. For the 2008 R2 box I have allowed an incoming rule to except echo requests for pings. Also, I am unable to connect to the shared folders on the 2008 R2 box.

Even using the parallels DCHP server with DHCP address I am unable to make the machines talk to each other.

My feeling is that there is nothing to route the traffic between the two but I thought thats what the whole host-only networking environment did. Also, I got this setup at one point so I know it works, but am frustrated that I can't get it to work again.

Here is what Parallels says about host only networking. It looks like what I want.

Thanks in advance for any help,

Please
In VM1: click Start -> Run and execute cmd.exe. Type in the appeared window command "ipconfig /all". Then, without closing the window, click Parallels Destkop menu "Help"->"Report a Problem", send a problem report (it is not necessary to provide description) remember the report ID.

Then do the same for VM2.

post here both report IDs
 
Report ID - 7923177 - Windows 2008 R2
Report ID - 7923203 - Windows XP SP3

Also, I run these VM's off a external HD that I use with two Macs. Both are running Parallels for Mac 5 and 10.6.6

According to the report, the Win2k8 VM is in the SharedNetworking mode (and XP is really in HostOnly). They need to have the same networking type to see each other
 
Opps, that is embarrassing. I guess I didn't switch it back when I was trying to fix it last week.

However, I still ran into the problem again. It seems that Host-Only networking will work fine when you get it up and running, however; it kept breaking on me. I found out why. As I said before I use these VM's on two Macs via an external HD. When I go back and forth between the two Macs I tend to suspend the VM's instead of shutting them down. When you switch from one Mac to another in a suspended mode something goes wrong with host-only networking. It can't resume from another Mac.

The fix is pretty easy, you just have to reboot the VM's. Then it will talk correctly with the Host-Only networking on the other Mac.

Thanks a lot though! I really appreciate your help and time!
 
Brent,

I am facing the same problem. I could not release IP address from the W2K8 Server to Windows XP. I have enabled HDCP at the server end. Both virtual PC are in my MBP. I am using the same parallel version.

Please help!!
