What distro do you use?

Don't get me wrong, virtualization is cool, but what is the point of running multiple Linux distros on one machine? They all essentially do the same thing. The only reason I can see using virtualization technology is for running Windows or OS X inside of Linux for certain applications. Running 2 or 3 Linux distros at once seems redundant.Tsuroerusu wrote:Xen is already taking over the world!!mowestusa wrote:This calls for a gear picture so we can see you running all three at the same time.KStorm wrote:Currently I use PCLinuxOS on one partition, Fedora Core 6 and Ubuntu Edgy on the others.

For servers, there's a huge advantage of Xen or other virtualization technologies. First of all, you can consolidate many servers onto one giant box. For example, instead of having multiple dual physical servers, you could have one big giant physical server and run many virtual servers off of it.
On the desktop, especially on Windows, virtualization is good for security, as you can run an OS in an isolated environment, and not risk things getting into it infecting your host environment.
For me personally, I just think it'd be cool to run muiltiple distros at once. Because, I like both say Fedora Core and SUSE, although I prefer SUSE for my daily usage, every now and then I'd like to use Fedora for whatever reason. With virtualization I could do that. Or I could run *BSD and Linux at the same time.

I guess, I get the idea behind Virtual Servers on one big machine, but I wonder why all of this Virtual Stuff is not going in the direction of jails under FreeBSD. That seems to be the coolest idea for servers. You can run isolated instances of different server services and web apps with unique ip addresses with out the bigger hit of multiple kernels and other redundant services and apps.Tsuroerusu wrote: Xen is mostly designed for servers, as it's not like a VMware Workstation, but more like VMware Server.

Does Linux even have anything like jails? (It seems unique to FreeBSD from what I have heard, NetBSD and OpenBSD have something similar, but not the same from what I understand.)
Why hasn't this caught on more than allocating 128mb of ram and CPU power to each Virtual Machine like QEMU, VMware, and Xen? (Just seems like with jails you could run secure webservices and server applications with a much lower spec machine than if you set up Xen on the same lower end hardware.)

I guess it depends on what you need out of your OS, if you look to share your box with other people or wanna lock it down, jails seem very nice. However if you're looking to consolidate a lot of servers, I think full on virtualization makes more sense. Because you're looking to not waste CPU power, if you have spare cycles, you're not using the full power that you have.mowestusa wrote:I guess, I get the idea behind Virtual Servers on one big machine, but I wonder why all of this Virtual Stuff is not going in the direction of jails under FreeBSD.

The "jail" feature is unique to FreeBSD, it's basically a kernel level virtual machine. There is something for NetBSD and OpenBSD called Sysjail, however the website seems to have disappeared, no idea why, and it does something different with the use of systrace.mowestusa wrote:Does Linux even have anything like jails?

I am not aware of any sort of jail stuff for Linux, however it's a quite compelling feature of FreeBSD. You could do a "chroot jail" under Linux, but an attacker can brake out of that, and that is not virtualization.
Well, if you wanna consolidate multiple servers onto one machine, it seems to make more sense making a full on isolation with kernel and everything, because for this you are looking to scale a lot of stuff, not just security.mowestusa wrote:Why hasn't this caught on more than allocating 128mb of ram and CPU power to each Virtual Machine like QEMU, VMware, and Xen?

Just kidding, guys. The only way I come close to running all three at the same time is to reboot into each one of them, because they are all, and Linux is, awesome!mowestusa wrote:This calls for a gear picture so we can see you running all three at the same time.KStorm wrote:Currently I use PCLinuxOS on one partition, Fedora Core 6 and Ubuntu Edgy on the others.

hmmm LSM's and selinux!mowestusa wrote: Does Linux even have anything like jails? (It seems unique to FreeBSD from what I have heard, NetBSD and OpenBSD have something similar, but not the same from what I understand.)
in a jail client A can DoS client B's resources and vice versa. If these are just apps for a single client, then use selinux.mowestusa wrote: Why hasn't this caught on more than allocating 128mb of ram and CPU power to each Virtual Machine like QEMU, VMware, and Xen?

I am using Arch Linux.
A bit OT, but since I am a new user here I could mention that the main reason that made me start listen to TLLTS was because of this topic which BTW was on the Arch Linux forum. I didn't know about the show before.
Great show! I have listen to it since then.

Finally a thread where nobody whines and moans about the audio quality. The Arch Forum earns major points on this one. May have to move Arch up on my "distros to try." SLED got a nice kick to the back of that line.PJ wrote:I am using Arch Linux.

Wow, I didn't actually think anyone would read the complete thread, it was more ar less some kind of reference for where I first heard about TLLTS.Vogateer wrote:Finally a thread where nobody whines and moans about the audio quality.
