### problem Before the upgrade to version 4.21.0, the DHCP server for VPC Guest Network tier included both the Guest Network Gateway and the DNS server defined in the zone as nameservers. However, after upgrading from version 4.20.1 to 4.21.0, the DHCP server only announces the DNS server defined in the zone. Consequently, all internal DNS resolutions fail due to this change. in 4.20.1 VPC VR /etc/dnsmasq.d/cloud.conf ``` dhcp-option=tag:interface-eth0-0,6,10.2.1.1,172.17.2.1 ``` in 4.21.0 VPC VR /etc/dnsmasq.d/cloud.conf ``` dhcp-option=tag:interface-eth0-0,6,172.17.2.1 ``` ### versions ACS: 4.20.1 OS: OL9 x86_64 hypervisors: KVM storage: NFS(SharedMountPoint) network: vxlan ### The steps to reproduce the bug 1. Create a VPC with "Default VPC offering" 2. Create a guest network with "DefaultIsolatedNetworkOfferingForVpcNetworks" under that VPC 3. launch a VM 4. verify /etc/resolv.conf are missing guest network gateway ip as nameserver ### What to do about it? _No response_ -- This is an automated message from the Apache Git Service.
