what vm solutions do people use

[Kelly Prescott]

My question says it all... What virtual machine solutions do you all use 
with Linux and speakup?
I use the amazon cloud for the most part, but I have some machines which I 
need virtual machines on and I wonder what people find works for them...
any ideas would be appreciated.

I haven't tried it with Speakup, but I use KVM here. It supports virtualized
audio devices if you specify the appropriate option when you start the VM.

It also supports virtual braille displays, which can connect to a real display
running on the host system.

I need a vm solution as well, so if you could send any info on setup and usage, I would appreciate it.

I use both user-mode linux, and virtualbox. What I like about
user-mode linux are two things. First, it doesn't require extra
software on the host. You need utilities to get networking going, but
the actual virtual machine could be run by any user without getting
the admin involved. Second, I like the fact that I can take "physical"
consoles from the virtual machine, and attach each one to for example
the host's physical console in a screen session. I get the virtual
machine's output from start to shutdown via speakup on the host
(grin). My server is a user-mode linux machine, which makes it very
portable. I could probably run it from a grml live cd on the host if I
wanted to.

What I like about virtualbox is that I can use the same virtual
machine on a gnu/linux, windows, and probably mac host as well. As
long as I'm willing to create a new configuration if switching from a
windows to a gnu/linux host for example, the virtual hard drive stays
the same, and the guest operating system won't know it's running on a
different host os. Virtualbox does also support virtual machine
extensions as long as the host processor has that capability, and many
other features. The workstation I'm writing this on is a virtual
machine inside virtualbox.

It should be easy enough to find "HOWTO" guides on the Web, so instead of
duplicating what they document better than I can in a mailing list post, I'll
give the highlights here.

There are basically two approaches: you can run kvm from the shell, or you can
run it via virt-install and virsh, which also have the advantage of supporting
other virtualization solutions such as Xen. VirtualBox is from Oracle (a
former Sun project) and has an extensive command line interface also, but I
haven't used it.

If you wish to run Kvm directly (as you may for some of its accessibility
features), I would suggest reading the manual page and selecting command line
options appropriately. On my system (Debian), the qemu manual page is the
place to start - see also qemu-img for creating virtual disk images.

If you're booting an ISO 9660 image that supports text mode, you can run
Qemu/Kvm so that it provides terminal (curses) output. This can be very
helpful during installation; I've booted Grml this way.

The audio and braille display support should all be in the manual page.
Virtual serial ports can be configured too.

I hope this is a helpful starting point.
