Hi Venkatesh,

OK, so does the instance get an IP address if you log into it‎ and tell it to send a new DHCP request? This is normally done by

    dhclient eth0

or

    ifdown eth0; ifup eth0

but it can depend on what the guest OS is.

‎If the guest _does_ then get its IP, I suppose the problem was to do with timing when the instance first booted.

If it doesn't, my next step would be to look in syslog on the network node, to see if the DHCP request is reaching Dnsmasq there, and how Dnsmasq responds to it.

Regards,
     Neil

Hi Venkatesh,

No IP probably means that the DHCP mechanism failed somehow.  Are you running a DHCP agent?
