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.
Dnsmasq starts as root, but it normally runs as another user. The
distributed code defaults to "nobody" but it might be a dnsmasq-specific
user on some Linux distros. (On Debian and Ubunutu, it's "dnsmasq").
Try making the file world-readable as a test, then tighten up the
permissions if you need to.
The logging is a bit confusion here: the second "read <filename>" line
is a lie, believe the first line.
HTH
Simon.
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.
Thanks,
Shashank

I ask these because Mac address and vm instances have always been a
hit and a miss for me personally.
S's have always been a pain to work with until now ..
