----------------------------------------------

             Summary: Bug in cloudstack virtual router (KVM) in Simple zone with public ips
/ DHCP Debian Wheezy specific
                 Key: CLOUDSTACK-8326
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8326
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: KVM, Virtual Router
    Affects Versions: 4.3.2
         Environment: Ubuntu 12.04.5 for Host
Debian Squeeze for VR
            Reporter: Ivan A Kudryavtsev


I've found several bugs in DHCP script /root/edithosts.sh

here:
\# don't want to do this in the future, we can have same VM with multiple nics/entries
\# sed \-i /,$host,/d $DHCP_HOSTS <- commented
and the same clear for $HOSTS file

Actually, this causes that if someone creates VM with some name, removes it and creates again,
then dnsmasq fails to lease DHCP offer because of such message in 

/var/log/messages-*
Feb 18 13:41:44 r-1184-VM dnsmasq[2640]: not giving name bill.domain to the DHCP lease of
176.XX.25.76 because the name exists in /etc/hosts with address 176.XX.25.130
Feb 18 13:41:44 r-1184-VM dnsmasq[2640]: not giving name bill to the DHCP lease of 176.XX.25.76
because the name exists in /etc/hosts with address 176.XX.25.130

The second bug is that /etc/sysctl.conf is not invoked during startup (it's known Squeeze
issue), that could be fixed in the /etc/rc.local like

/etc/init.d/procps restart

otherwise there are conntrack errors in dmesg.
