Ivan A Kudryavtsev updated CLOUDSTACK-8271:
-------------------------------------------
Description:
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.
