Re: F10 -- Xen, VirtualBox, or VMWare?

I would vote KVM as well.  Support for native disks and USB devices is
trivial.  However, the selling points for me of all of them are these:

1. Xen == Novel/Microsoft (yes, MS bought rights to Xen, and development
stopped/slowed to nothing)

2. VMWare == Windows host focus.  Linux support is sub par and building
their kernel modules may always be an issue.

3. KVM is in the mainline kernel and gets a lot of (good and bad)
attention.

4. Virtualbox == some really old code from SUN.  It requires its own
device driver and can conflict with KVM.

What of Rahul's comment, further up the thread, saying "KVM (assuming you have the hardware support) with Virt-manager (if you
need a GUI)"??

How do we tell if we have the hardware it takes? (And I for one do need a GUI for anything very complicated.)

5. I am a command line/scripting person, and starting a series of VMs
based upon KVM is easily made to be automatic.

I have no problem typing:

$ sudo qemu-kvm -hda /dev/sdb1 -net nic -net user -m 1024 -soundhw all

Aaaiiieeeee! <runs screaming into the middle distance> Such CLI-fu is beyond all hope for me. I prefer the CLI where feasible, to be sure, but I won't live long enough to be able to type a whole such line. So what's your take on this Virt-GUI? Is it part of KVM?
Typing one line? I avoid GUI because even when I know exactly what I want to do I have to go look through menu after menu and see if the GUI author wanted to allow me to do what I want. Feels like fly-tying wearing mittens.

Under GNOME you can add a launcher to your tool bar which executes a command line (which all launchers actually do) and have it do just what you want. Like having an icon for each of several virtual machines...

Can we just do "yum install kvm" or "yum install kvm virt" and expect to get, if not success, a message we can use to make success possible? Something, I mean, more encouraging than "Go replace your motherboard, hard drive, and xkcd-bus, you idiot!"?? Or is this whole alternative to dual booting still for Alpha Plus Technoids only?

Dumb question on a small point of purism, btw. IF (big if) I understand correctly, some if not all of these virtualizers actually contain (in some sense of "contain") a full install of XP or whatever, wrapped in linux like a mystery inside an enigma -- or a cyst inside an organ. Does KVM?? I'd a lot rather get rid of all the products of Redmond if I can ....

No, you get to do a Windows install in your virtual machine.
