I would appreciate if you could share your LKVM performance (if any).
How to do that? I can share benchmarks or command outputs if anyone guides me
I tried installing Chromium OS and XP on VirtualBox. both work smooth. XP even works in Seamless mode.
VirtualBox's architecture is not dependent on hardware virtualization whereas Linux KVM is.
Here is a simple scenario to get started with LKVM:
First of all make sure that you have the following device:
$ ls -l /dev/kvm crw-rw----+ 1 root kvm 10, 232 2010-06-12 04:01 /dev/kvm
Secondly, your "userid" should be part of group "kvm"
Thirdly open up a terminal window and start up "top" to observe resource consumption
Fourthly start a LiveCD Guest OS in a KVM environment.
qemu-kvm \ -enable-kvm \ -vga cirrus \ -m 1024 \ -boot d \ -cdrom /path/to/a/liveCD/iso/file
In Debian/Ubuntu "qemu-kvm" may be some other name.
The above command will start up KVM and boot your LiveCD iso as a Guest OS. Once the Guest OS boot process is complete you will have access to it's desktop. Since we have not given any NIC params, it will be NAT'd.
Keep an eye on "top" to see cpu idle and memory usage during the boot process as well when the Guest OS is booted and you are using it's desktop e.g. OO, FF etc. You can shutdown the Guest OS by following the normal shutdown procedure.
I hope the above will get you started on KVM. I am keen to see your test results; let us know.
