Re: [libvirt-users] How to add static routes?

Hello i have several libvirt hosts (CentOS6, kvm), each with an internal libvirt "default" network with "forward mode='route'". I have two questions concerning static routes. To give some context: On each of my libvirt hosts there is a VM acting as a OpenVPN-gateway to the other libvirt hosts. [A] How can i add a persistant static route on the libvirt host to one of its guests?

Someone had already asked this on this list in 2011 but apperently did not receive an answer [1]. Likewise, i found that a /etc/sysconfig/network-scripts/route-virbr0 does not get applied when libvirt starts its default network. [B] How can i make libvirt's dnsmasq push static routes into the guests? Apperently dnsmasq supports pushing of static routes using DHCP options 33 or 121 [2], e.g. "--dhcp-option=121,x.x.x.x/yy,z.z.z.z". But i did not find how to add that to a libvirt network declaration. I know that if i had [A] working, the host could redirect the IP traffic on behalf of the guests, but i'd like to avoid the resulting extra hop and the flood of ICMP redirects. Please advise. Cheers /nils.
