Hi All
After our ACS is upgraded to 4.11.3, the VM on the shared network usually
loses its IP address (it cannot get an IP address in the guest VM).
Analysis of the cloud.log in vr, we found that sometimes restarting or deleting
the A VM will cause the B VM to disappear in /etc/dhcphosts.txt.
Because /etc/dhcphosts.txt is inconsistent with the data in
/var/lib/misc/dnsmasq.leases. This triggers delete_leases to remove the IP
address of the B VM from the DHCP server.
