ustcweizhou opened a new pull request #3477: RvR: Set up metadata/password/dhcp server on gateway
IP instead of guest IP in RVR
URL: https://github.com/apache/cloudstack/pull/3477
 
 
   ## Description
   
   When we create a vm in the network with redundant VRs, the lease file in the vm (for example
/var/lib/dhcp/dhclient.eth0.leases) shows the dhcp-server-identifier is the guest ip (not
vip/gateway) of master VR. That's the ip ipaddress where the vm fetch password and metadata
from.
   if we stop the master VR (then backup will be master) or restart the network with cleanup
(VRs will be created), the guest ip of master VR changes so vm are not able to get metadata/ssh-key
using the ips in dhcp lease file.
   
   Setting up metadata/password/dhcp server on gateway instead of guest IP in redundant VRs
will fix the issues.
