Re: Running DHCP Server on a Linux guest

[Aria Bamdad]

If your guest is connected to the network using a vswitch, then
did you define the vswitch as type IP or ETHERNET.  I think you
would need it to be ETHERNET in order to see those types of
packets.  Others can correct me if I am wrong.

Re: Running DHCP Server on a Linux guest

[Stricklin, Raymond J]

Something we ran into with SLES10 SP1:

# this option is REQUIRED as of SLES10 SP1
# the DHCP server will unicast DHCP ACKs without it.
always-broadcast on;


This must be in dhcpd.conf on the server, or the linux clients will
never receive their leases. It's possible this problem does not exist if
you are using a layer two (ETHERNET) VSWITCH.

ok

We've had a heck of a time trying to get DHCPD running on SLES10.  I've
noticed that The Linux guest isn't accepting broadcasts.  When typing
tcpdump -nepi eth0 broadcast on regular x86 servers, it spits out all
