Package: neutron-dhcp-agent
Version: 2014.1.1-2~bpo70+1
Severity: normal

Dear Maintainer,

After installing and following the OpenStack installation guide I faced an issue with instance not getting his IP from the DHCP server.

After some investigation, syslog reported:
/var/lib/neutron/dhcp/{id}/host : Permission denied

And as the dnsmasq process is launch as "nobody", and as the /var/lib/neutron is only rx for owner and group (neutron) only (no right for others), the dns masq process was unable to read his allocable IP pool.

I just done a chmod o+x /var/lib/neutron and it worked.

Could you fix it in the package (finding a way to run dnsmasq as neutron user or setting the suffisant permission on the directory)?

Thanks for your work.
