However, I would like to see if I can do all of this on one server. The choice that comes to mind immediately is vmware, but since I am required to use all freeBSD, I would be using vmware via linux compatibility mode, which is somewhat slower than native vmware on linux. I have two specific questions: 1. Is jail ready for prime time ? that is, taking into account stability, performance, and _security_, would you feel comfortable running multiple servers on a single machine where the relative contents of the machines were sensitive (in terms of performance and security) ? 2. Any comments on the differences between using vmware and jail ? Why would I choose vmware over jail ? Does jail offer the same memory usage guarantees, etc. ? Any thoughts / comments on vmware vs. jail, and the viability of using jail on a multi-system system are appreciated. --joesh _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
