Yes, Fedora seems to be popular for most KVM users :-)

I'll give it a shot.

The VM won't start at all.  Nothing seems to point to gtk-vnc.

The libvirtd output is:
libvir: QEMU error : QEMU quit during console startup
Could not parse VNC address

Virt-manager pops up a console with this error:

virDomainCreate() failed QEMU quit during console startup
Could not parse VNC addresssudo echo 1 >> /proc/sys/net/ipv4/ip_forward
sudo /sbin/iptables -t nat -A POSTROUTING -s 192.168.21.150 -j MASQUERADE

the "Details" window within the popup provides this:

Unable to start virtual machine '<class 'libvirt.libvirtError'> 
virDomainCreate() failed QEMU quit during console startup
Could not parse VNC address

Traceback (most recent call last):
   File "/usr/local/share/virt-manager/virtManager/console.py", line 
402, in control_vm_run
     self.vm.startup()
   File "/usr/local/share/virt-manager/virtManager/domain.py", line 377, 
in startup
     self.vm.create()
   File "/usr/local/lib/python2.5/site-packages/libvirt.py", line 228, 
in create
     if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)
libvirtError: virDomainCreate() failed QEMU quit during console startup
Could not parse VNC address

My graphics line in my xml is:

<graphics type='vnc' port='5900'/>

I've also tried values 1 and -1 for port.

Thanks again,
