Your etc_xen_win7.cfg says "on_reboot='destroy'" twice, needs little 
cleanup.
To be honest, many of HVM options looks like mysterious magic to me, 
although they are described in the documentation, so I almost always use 
the same configuration with minor changes. Take a look on the config 
file I use to run w7. "ioemu" are commented out but still there for 
reference, my w7 has PV drivers installed.
name    = 'w7VM'
memory  = '2048'
#vif     = [ 'mac=XX:XX:XX:XX:XX:XX,bridge=xenbr01,type=ioemu' ]
#disk    = [
#            'phy:/dev/mainVG/w7VM-disk,ioemu:hda,w',
#            'phy:/dev/mainVG/w7VM-data,ioemu:hdb,w',
#            'file:/mnt/masters/ISO/w7.iso,ioemu:hdc:cdrom,r'
vif     = [ 'mac=XX:XX:XX:XX:XX:XX,bridge=xenbr01' ]
disk    = [
            'phy:/dev/mainVG/w7VM-disk,hda,w',
            'phy:/dev/mainVG/w7VM-data,hdb,w',
          ]
vfb     = [ 
'type=vnc,keymap=es,vnclisten=0.0.0.0,vncdisplay=11,vncpasswd=XXXXXXXX' ]
boot = 'c'
builder = 'hvm'
kernel = '/usr/lib/xen-4.0/boot/hvmloader'
device_model = '/usr/lib/xen-4.0/bin/qemu-dm'
usbdevice='tablet'
localtime=1

on_poweroff = 'destroy'
on_reboot   = 'restart'
on_crash    = 'preserve'

s/mamem/maxmem/ ??

In any case, I would not expect the amount of RAM to be the issue. Even 
1GB is enough to run w7 without applications on it.

Start checking if your vncserver is even listening, with "netstat -lnp | 
grep qemu-dm". Make sure your access to it is not blocked by a firewall.

B[locked] is a normal state for a domain that is up and healthy. In any 
given moment only few domains are in running state, the rest are 
awaiting for resources or simply have nothing to do.
