Naoki Sakamoto commented on CLOUDSTACK-3533:
--------------------------------------------
I think you ask me about following result (no_dhcp_release) in "edithosts.sh".
=======================================
(L83)
command -v dhcp_release > /dev/null 2>&1
no_dhcp_release=$?
(L104)
if [ $no_dhcp_release -eq 0 ]
then
#release previous dhcp lease if present
logger -t cloud "edithosts: releasing $ipv4"
dhcp_release eth0 $ipv4 $(grep "$ipv4 " $DHCP_LEASES | awk '{print $2}') >
/dev/null 2>&1
logger -t cloud "edithosts: released $ipv4"
fi

I found "edithosts: releasing 10.0.0.2" and "edithosts: released 10.0.0.2".
Then I think no_dhcp_release = 0 at that time.
If you ask me the command existence.
I execute "which" like following.
root@r-11-VM:~# which dhcp_release
/usr/bin/dhcp_release
root@r-11-VM:~#
> [IPv6][dnsmasq] VM not able get ip from dhcp which is previously assigned to
> vm
