Re: Adding a static route to the SSVM for remote NFS server
I can add the route manually but when the SSVM is rebooted it loses that route.
I edited the /etc/network/interfaces file and added it there but it still gets overwritten on reboot.
Do you know how to add it permanently across reboots ?

Yes, that should work. I did it some time back in my environment where NFS server is sitting in a separate subnet (in LAN), and public NIC/gateway in the SSVM was used to route the packets to/fro NFS server. We have added static route via the private/management NIC because the NFS server sits in LAN.
Let us know how it goes.

Subject: Adding a static route to the SSVM for remote NFS server
I am doing basic networking with 2 NICS (one for management/storage and the other for Guest traffic).
When you configure the physical NIC/bridges you can only define one default gateway so I do it for the guest traffic which means the routing table on the SSVM ends up as -
root@s-1-VM:/etc# netstat -nr
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
0.0.0.0 172.30.4.1 0.0.0.0 UG 0 0 0 eth2
22.214.171.124 172.30.3.1 255.255.255.255 UGH 0 0 0 eth1
126.96.36.199 172.30.3.1 255.255.255.255 UGH 0 0 0 eth1
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
172.30.3.0 0.0.0.0 255.255.255.192 U 0 0 0 eth1
172.30.4.0 0.0.0.0 255.255.255.128 U 0 0 0 eth2
where 172.30.3.0/26 is the management network and 172.30.4.0/25 is the guest network.
My NFS server has an IP of 172.30.5.2 so it is on a different subnet which means the the secondary storage would have to run over the guest NIC if I am understanding this properly.
I want storage over the management NIC. Based on some advice on this mailing list I configured storage to use the same bridge (KVM label) as management but it won't build ie. it errors on the storage traffic part I suspect because the subnet details I enter are not part of the management subnet.
Can I just add a static route to the SSVM for the 172.30.5.0/28 subnet and would this work or is there a better way to do it ?
On a more general note with basic networking the assumption seems to be you run everything over the same NIC and if you don't it seems to cause no end of problems :)
