Hi,
I'm having network issues with a Windows Server 2008 R2 guest running 
on an F19 host. The guest has a static configuration and is able to 
ping itself and the host it is running on, however cannot ping the 
gateway, any other hosts on the local network, or external hosts. A 
RHEL 6.4 guest on the same host with a similar static configuration 
works normally.
Iptables/firewalld on the host are switched off and the network 
definitions in the XML for each VM (Windows/RHEL) are the same. The 
virtio network drivers are installed in the guest. The guest was 
created from a Win 2008 R2 template, which was created from a VM 
imported from oVirt 3.2. Software versions below.
Just to be sure, iptables/firewalld!=Windows Firewall. Is there a rule 
in the windows firewall to allow ping or is it disabled?
...
Are there any manual configuration steps required on the host to 
support Windows guests? Are there any particular diagnostic steps I 
could take to try and narrow down the cause?
Don't think so, just converted a Windows2008R2 datacenter guest from 
Vmware to oVirt and it ran, after adding virtio drivers or using e1000 
and/or ide disks.
...
Versions:
-oVirt 3.3.0-4
-F19 3.10.11-200
-QEMU 1.4.2-9
-Libvirt 1.1.2-1
-VDSM 4.12.1-2
-virtio-win 0.1-52
Your problem looks like the problem René had with his Solaris guest, its 
a recent thread. Turned out that setting -cpu Nehalem by ovirt caused 
networking in the Solaris guest to fail.
Don't think this is your problem though since lots of people run Windows 
guest without problems.

Regards,

Joop
