I did try commenting the ::1 entry in /etc/hosts file. I still see this
issue.

For fully-virt  / HVM guests you should see a 'qemu-dm' process
listening
on the port associated with VNC (something around 5900+). If you don't
then this is the primary problem to address - the qemu-dm*log file may
be useful. Also grabbing the command line for qemu-dm active process
should indicate what port it tried to start on. In my case:

# virsh dumpxml  rhel4i386 | grep graphics
    <graphics type='vnc' port='5900'/>
# ps -axuww | grep qemu
root      4005  0.0  0.1  64616  5132 ?        Sl   20:05   0:00
/usr/lib64/xen/bin/qemu-dm -d 2 -m 500 -boot c -serial pty -vcpus 4
-acpi -domain-name rhel4i386 -net
nic,vlan=1,macaddr=00:16:3e:39:f9:76,model=rtl8139 -net
tap,vlan=1,bridge=xenbr0 -vncunused -k en-us -vnclisten 127.0.0.1
# netstat -t -a -n -p | grep qemu
tcp        0      0 127.0.0.1:5900              0.0.0.0:*
LISTEN      4005/qemu-dm        
# virsh dumpxml  rhel4i386 | grep graphics
    <graphics type='vnc' port='5900'/>
