Subject Re: Regarding the BLOCKER bug Cloudstack-3589 VM created from VPC network is not getting IP
Date Sun, 21 Jul 2013 10:49:48 GMT
H Sheng et al,

I have no overview of what effect my patch has on guest vm's. It is
supposed to only generate a dnsmasq.conf for vpc-router-vm's. not
guestnetwork-vm's. I am happy to look at it, but have no overview of the
issue yet. Should a sepperate dnsmasq.conf instance be created for vpc
routers to deal with the different nics?
