vmware issues

Good-day,
I have a peculiar problem and i need some help
I have installed the following applications on my laptop, GNS3 AND VMWARE
On the vmware app i have installed windows xp and cisco unified callmanager 8.6.2
I have connected the gns3 application to the vmware app using the vmware network adapter VMNET1
I can ping from the gns3 app to the cucm app on vmware
I can also ping from the gns3 app to the windows xp operating system running on vmare
But the issue is
i created two loopback interfaces on the windows xp os, and i cannot ping from the gns3 app to the loopback interfaces
but i can ping from the gns app to the vmware accelerated amd pcnet adapter on my xp station
And all interfaces all belong to one subnet.

Thanks
