[gentoo-user] VM experiences and faqs?

  I have a 4-core Intel i3 (/proc/cpuinfo dump below) running 64 bit
Gentoo.  I want to try hosting 32-bit Gentoo and also OS/2 Warp 4 on it.

I use vmware-server and also kvm for VMs.

Both work.

vmware:

I don't really like the web-gui, it sometimes is buggy and unreliable,
has ssl-issues and you need a specific firefox-plugin to access the
console of the VMs. It brings its own tomcat-server etc., somehow not as
minimalistic as we gentoo-users like things ...

I also don't like the need to always log into that gui as I am
single-user here anyway. Might be some small hack in PAM or so, never
researched that.

Aside from these issues vmware runs fine, and I like the fact that I am
able to connect 2 very similar USB-serial-converters to one VM,
something that KVM is not yet able to support AFAIK (I need them for my
Suunto heart-rate-monitor and GPS, both cables have the same USB-id ...).

This is the main reason why I haven't yet fully migrated my own VMs to ...

KVM:

It feels (and is) faster. Less overhead.

I really appreciate the fact that it is in the kernel, you just enable
it once and it is there ...

Very little overhead, VMs feel fast and snappy.

For gui I use virt-manager on top of libvirt, nice feature to have all
your VMs at hand in one small gnome-applet ... (it should be possible to
also control vmware-servers with libvirt, but this has been unreliable
for me).

I like the virtio-drivers for block- and network-devices. Fast and direct.

The network-setup for kvm is somewhat more complicated at first, all
that bridging and qtap and stuff, vmware does hide that more from you or
somehow makes it easier to administer (my experience ... it is very
likely that I don't know things ...).

-

In general both systems work fine, I use vmware out of historical
reasons (KVM wasn't there or as ready when I started using VMs) and KVM
as it seems to grow up and become a really powerful and open alternative.

In fact it is already ...

Hi,

I'm using app-emulation/virtualbox-bin and it works really great, even
forwarding of usb devices, but I only tested WinXP in the box for
printing purpose. If you wanna have an open source product, consider
app-emulation/virtualbox-ose (open source edition).

I installed OS/2 Warp 4 with KVM and it "just worked" (TM)! It is also 
incredibly fast (on a Core2 Duo).

But bear in mind the the OSE has no USB support.

  Thanks for that report.  I'll try it out.

KVM is nice.

Just before I recompiled the kernel on a dedicated server I will very
likely never see .... then emerged the packages and booted the first vm,
controlling it via ssh and libvirt ... nice, it is ...

I've found VirtualBox to be a bit faster than kvm only because of
their highly optimized graphics driver.

The vbox gui is also nice, but requires qt4 (a pain for us gnome
users).  Anyone know if kvm has a similar gui for managing virtual
machines?

But my real reason for replying is to ask you why you're interested
in OS/2.  I thought IBM lost interest in it ages ago.  Am I wrong?

  I have Galactic Civilizations V2.5, an OS/2-only game, on a 400 mhz
PII running Warp 4.  I still love it after all these years.  That
machine has lasted a lot longer than it should've, and it's damn loud.
Virtualize that, and I'll be one happy camper.
