Your guessing is completely right! I am using no-hosts in dnsmasq.conf. Now
the new codes work greatly in my environment.

But another issue I found is, the IP binding can't be really released even
after remove the config files and manually call dhcp_release. So when I
create another VM with the same IP address, it will report duplication.

dnsmasq.log is something like:
---------------
Feb 15 06:12:45 dnsmasq-dhcp[3521]: DHCPRELEASE(eth2) 10.11.0.3
fa:e1:51:0b:a5:00
...

Feb 15 06:13:13 dnsmasq[3521]: inotify, new or changed file
/etc/hosts.dhcps//fa:e9:4a:40:7f:00
Feb 15 06:13:13 dnsmasq-dhcp[3521]: read /etc/hosts.dhcps//fa:e9:4a:40:7f:00
Feb 15 06:13:13 dnsmasq[3521]: duplicate dhcp-host IP address 10.11.0.3 at
line 1 of /etc/hosts.dhcps//fa:e9:4a:40:7f:00

....
Feb 15 06:13:23 dnsmasq-dhcp[3521]: DHCPDISCOVER(eth2) fa:e9:4a:40:7f:00 no
address available
Feb 15 06:13:26 dnsmasq-dhcp[3521]: DHCPDISCOVER(eth2) fa:e9:4a:40:7f:00 no
address available

Anything wrong?
