Etherchannel - NIC Teaming

Hello Experts,
 
I am trying to configure Etherchannel to support NIC teaming.
The 2 NIC cards of a VMserver is connected to my 6500 switch on port gi7/18
and 19. I could see port channel is up and it shows Gi7/18 & 19 as it members.
The ports are also up. But I am unable to have IP connectivity get established
from VMserver.
 
I could get the IP connectivity established only when any of
the Interface Gi7/18 or 19 is made manually down. Could you please anyone help
me to resolve this. Is this anything related to STP. Please find my
configuration below.
 
interface Port-channel1
 switchport
 switchport trunk
encapsulation dot1q
 switchport mode trunk
end
!
interface range
GigabitEthernet7/18 - 19
 switchport
 switchport trunk encapsulation dot1q
 switchport mode trunk
 channel-group 1 mode on
end
