Not sure how to get SNAT working without OVS as I am using nova-network. any suggesstions??

actually its because there is no source NAT happening for outgoing ICMP packets from the VM.

doing tcpdump on eth0 of the compute host I see following. The source ip is the private ip of the VM, 10:12:13.359045 IP 10.0.0.2 > 10.160.2.111: ICMP echo request, id 941, seq 26, length 6

I have already assigned 14 IPs to my tenant and that is why I can manually assign floating IPs to VMs.

Its the auto part that doesn't work.

HI I am using FlatDHCPManager to assign private IPs to VMs. I have a 10.0.0.0/24 private network created for that.

I also have a public floating ip pool and VMs are pingable from outside using floating ip address.

I can also ping from inside the instance, compute node/controller mgmt ip as below, but I cannot ping the gateway ip for this subnet.

I don't know why I cannot access internet from instance when instance is accessible from outside.

HI,

I have Juno running on Ubuntu 14.04. I am able to start VMs fine on my setup, but after I added the "auto_assign_floating_ip=True" in nova.conf file , The VMs fail to spawn giving an error

line 772, in floating_ip_allocate_address\n raise exception.NoMoreFloatingIps()\n\nNoMoreFloatingIps: Zero floating ips available.\n\n']

But I made sure there are more than enough floating IPs available. Also if I remove this line from the nova.conf file and associate a floating ip after launching a VM , it works fine.

The auto assignment of floating IPs in not working. Any ideas how to make it work or this is bug.

Thanks for the help.

i can assign floating ips manually but when I set it to auto_assign_floating_ip=True

in nova.conf then VM fails to spawn.

I am facing same issue....

My project has enough floating IPs assigned, but I stiil get this error

"NoMoreFloatingIps: Zero floating ips available".

HI ,

I installed Havana on Centos 6.4. The deployment went smooth . but the VM cannot be started.

I think I am hitting 977555 which requires update of dnsmasq. yum update tell me that I already have the latest version. What version do I need if not the one below?

also pasting relevant logs from compute node.
