This is an easy way to install software that, when unpacked, is larger then a DVD, but don't want to copy it to the local drive every time. I have a few ISO-images of around 14Gig with software on it. Just connect that to the virtual machine and install from there. :) -- Joost

No, that's the iso I just happened to have attached to that vm -- it has no effect on the host. But my CD player does show up in the dialog box, so I have no idea why yours doesn't.

Every time I create a new virtual machine it automatically has a virtual CD/DVD player on which I can mount ISO files. Just tell vbox which ISO image you want mounted on the virtual CD player and start the vm. Are you seeing something very different at your end?

Should someone get a shell in either of these VM clients, would they even be able to determine that they're not on hardware (using full virtualization)? 3. Do the VMs see themselves as being on a LAN (e.g. 192.168.x.x), or do they actually share the hardware with the host? 4. Do you communicate with them via, e.g. SSH and/or X? Thank You (been hoping to find someone who knew both VB and KVM :-) )
Re: [gentoo-user] Re: Gentoo Virtualization
1) Security is for exploiting 2) If they are well versed on the drivers that virtualization technologies use, then yes they can tell they are on a virtual machine and not on dedicated server. 3) You can bridge network connection physically on the network minus the nic of course 4) Virtualization servers VMware, VirtualBox offer clients to connect to the servers, ssh, sftp is also possible as is done with regular servers.

I'm not a computer professional, so I'm not the best one to give advice about security. I can tell you that both vbox and kvm are built on top of a qemu base so they share a lot of code. The principal advantage for vbox is its nice gui interface to the massive list of qemu command-line options, and its highly optimized virtual graphics driver, which is what make vbox faster than kvm. If you don't need the fancy fast graphics driver (for your server) then it's just about a tossup between the two, both being based on qemu.(Oh, but vbox is very fast even without hardware virtualization support, and kvm isn't.) Networking is anywhere between trivial and a nightmare, depending on what you need it to do. Both by default just work when a guest is talking to the internet via your host machine, but then it's difficult communicating with the guest locally. There are ways to do bridging, firewalling, making a virtual lan between guests, and lots of fancy stuff, but then you really need to know how to use all those fancy options (which I don't). I use both of them to run Windows guests using the default network settings (no custom configuration whatever) and I use samba on the host to share files with the guests, which is very easy. I suspect that running a virtual server might require some network tweaking to make a decent job of it, but I'm only guessing. I hope some experts can add to or correct the above.

Well, not an expert by any measure here, but I have been using Vbox for about a year (with a variety of both hosts and guests), and I will mention that networking with it is an absolute breeze 9 out of 10 times. Bridged connections, internal networks (client to client visible only, great for hosting mysql on one guest and apache on another), host-only (internal with a virtual connection into it on the host, only worked with this on Windows hosts), NATed connections through the host (not optimal for servers, but the default and great for initial builds and 'simple' work with a guest). I also run 3-4 guests at a time with no problem on my meager little Core 2 duo, 3.0ghz, 4gb ram. -- Poison [BLX] Joshua M. Murphy
