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.
FIxes#3409
In order to reduce memory footprint and improve boot speed/predictability.
The following changes have been made:
- add vm.min_free_kbytes to sysctl
- periodically clear disk cache (depending on memory size)
- only start guest services specific to hypervisor
- use systemvm code to determine hypervisor type (not systemd)
- start cloud service at end of post init rather than through systemd
- reduce initial threads started for httpd
- fix vmtools config file
Fixes#3039
