Message #18929
Instances not getting their IPs from dnsmasq
*Dear Stackers,*
*Sorry if that question has already been discussed multiple times but I am
currently stuck trying to understand why none my instances are getting an
IP from dnsmasq. *
*
*
*I am running Folsom on Ubuntu 12.10 in VLANManager mode and multi-host
configuration (one nova-network per compute node).*
*
*
*Everything seem to be configured and operating properly excepted last
mille IP @ assignment from dnsmasq.*
*
*
*Running disk image is
cirros-0.3.0-x86_64-disk.img<https://launchpad.net/cirros/trunk/0.3.0/+download/cirros-0.3.0-x86_64-disk.img>
*
*Any help would be greatly appreciated.*
*Many thanks*
*Patrick*
