Re: vmware Questions
A rule of thumb is to configure as much service as you need (in this case, dhcpd), with as little overhead as you can get away with (a simple jail vs. a full-blown VM).

Thank you! That is exactly the kind of input I was looking for. As soon as I read yours and Frank Staals' mention of jails, it clicked. A true jail will have a little version of as much of the FreeBSD world as dhcpd needs to run. This should be much easier on resources and more predictable as to results. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]" ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

vmware Questions
If one has a FreeBSD system that has 1 gigabyte of RAM and a 1-GHZ processor, would it be possible to run a couple of vmware instances of FreeBSD? I want to set up a DHCP server on each virtual machine and configure one to be optimized for DHCP failover and dynamic leases while the other is dedicated to static bootp service. It would be much easier for the 2 instances of dhcpd to run in separate machines, so to speak, since they normally use the same named files for logging and configuration. What sort of a performance hit does one usually see on a virtual machine? When we run dhcpd on a normal FreeBSD system of the type described above, the system is normally loaded around 0.05 or so so it isn't having to work too hard. Thanks for any help as to what vmware port is best. The platform is FreeBSD and the 2 virtual machines will also be FreeBSD if that makes any difference.

More VMWare questions
Hello all, I have just loaded VMWare3 from ports, only because I could not get the Linux version 4 to load correctly. But now when I input the license key that I have, it says that it cannot be found or doesn't match available licenses. Has anyone else bumped into this scenario? If so, what is fix? Is there a workaround for this license key issue? Any (and all) help is greatly appreciated. Thanks, Ron Clark __ Do you Yahoo!? Yahoo!
