I am trying to do something like this

nova boot --flavor m1.large \
--block-device source=image,id=736f014f-8907-4e1e-9e02-cd4b04c4adb2,dest=volume,size=40,shutdown=preserve,bootindex=0 \
--nic net-id="b1ef8720-6333-4ddc-810d-cf04b654ca2b",v4-fixed-ip="" \
--nic net-id="91f91de6-4aa8-447c-b129-eb4201d99637",v4-fixed-ip="" \
--security-groups sec-group1,sec-group2 --key-name gh-keypair1 --user-data deploy.xml  \

But I am getting this error

Error: Failed to launch instance "server1.test.local": Please try again later [Error: No valid host was found. Exceeded max scheduling attempts 3 for instance 43a2c6a1-b04e-4791-bb03-0a5b892dcb44. Last exception: [u'Traceback (most recent call last):\n', u' File "/usr/lib/python2.7/dist-packages/nova/compute/", line 2054, in _do].

When I remove the fixed-ips then the deployment goes through fine

nova boot --flavor m1.large \
--block-device source=image,id=736f014f-8907-4e1e-9e02-cd4b04c4adb2,dest=volume,size=40,shutdown=preserve,bootindex=0 \
--nic net-id="b1ef8720-6333-4ddc-810d-cf04b654ca2b" \
--nic net-id="91f91de6-4aa8-447c-b129-eb4201d99637" \
--security-groups sec-group1,sec-group2 --key-name gh-keypair1 --user-data deploy.xml  \

The network does have DHCP on. Is this what's causing the problem or this is something else?

you should look at the logs under /var/log/nova and /var/log/neutron (if you are using neutron). It seems to be a network problem so your best bet is neutron logs! Update OP with these logs (especially nova-scheduler.log, nova-compute.log and neutron logs).

So it is a strange issue that when I use --block-device, I get this problem but if I create a volume and attach it then I am fine :/ I am guessing this is some sort of timeout.

If you are Trying to assign static IP address then this openstack cli command worked well for me:

openstack server create --flavor m1.tiny --image Cirros-0.3.4 --nic net-id="3aa113b3-0312-4ce7-b371-07acaba910f1",v4-fixed-ip="" --security-group default --key-name trystack test2

The Nova boot worked as well but with a deprecation warning:

nova boot --flavor m1.tiny --image Cirros-0.3.4 --nic net-id="3aa113b3-0312-4ce7-b371-07acaba910f1",v4-fixed-ip="" --security-group default --key-name trystack test3

But it seems like your problem is rather a host issue. Check nova service logs and your resources as well.
