Thanks for your prompt reply, Simon and Harish. I used the exact format suggested (mac,ip,lease).
Additionally, I see this in the logs when dnsmasq starts, dnsmasq[16686]: cannot read /var/run/_root_root_vdhcpd200.dhcp_hosts.cfg: Permission denied dnsmasq[16686]: read /var/run/_root_root_vdhcpd200.dhcp_hosts.cfg That is a bit confusing. I made sure the user and group are right and dnsmasq is running as root. >>Can you do an arping from a computer from an another hub to a specific >>VM instance ?? >>Is it the same when physical machines are added to the config file ?? Harish, yes. Arpings to the IPs assigned works. I am only adding guest machine information into the hostsfile. The problem is dnsmasq overlooks --dhcp-hostsfile completely. I even used the 'static' keyword in --dhcp-range=<startip><,dstip><,mode> Are there any reasons why dnsmasq would do that? The options passed look good.
