Dear Pham,
Dear List!
I would like to present a modified version of gem5 that simulates the
behavior of a virtualization layer and can simulate virtual machines.
You may download it from http://ece.ut.ac.ir/DSDLab/virtual-gem5.tar.gz
For more information on how to run this, see
gem5-with-virtualization-support.README inside. And if needed, don't
hesitate to contact me :)

Hi Seyed,
I am very interested in having the code if possible. Please let
me know the best way to get it.
Thanks a bunch!

Hi,
See Virtual-GEMS paper. My patch is similar to this.
http://www-mount.ece.umn.edu/~jjyi/MoBS/2009/program/02D-Garcia-Guirado.pdf
<http://www-mount.ece.umn.edu/%7Ejjyi/MoBS/2009/program/02D-Garcia-Guirado.pdf>
For a brief overview:
- It works in FS mode.
- Memory model is Ruby.
- Multiple instance of "system" is fired up for each VM and then
we properly connect ports of them to ruby.
- You can specify the start-up scripts for each VM. if you do
not specify, you can get terminal with m5term.
- It does not kill other features of gem5 and you can work with
ruby_fs or others as before.
- It supports vCPU
- ...
limitations:
- I/O is not shared (it is dedicated for each VM. like
Intel-VT's direct I/O)
- We do not run a hypervisor. We just simulate the behavior of
the hypervisor.
- ...
It is not published yet.
We have submitted a paper about it. It's under review.
If you are interested, I may send you the code :)
Let me know!

That would be nice. Could you briefly describe your
virtualized environment in Gem5?
I guess your patch has not been committed to the public tree
yet? If so, please let me know the best way to get access to
that.
Thanks,

It is very hard to run a full hypervisor in gem5 since the simulator is
not a complete environment.
However, if you want to run virtual machines on gem5 to have a
virtualized environment, i might be able to help.
I have a patch for that....
Its similar to Virtual-GEMS .

Hi,
I am wondering if it is possible to run virtual machine(s) on Gem5
setup using for example KVM, Xen, VMware ESX...? Recently, I saw a few request
change-set to the gem5-dev for the KVM support, but I am not sure if it is
available to the public yet?
Thank you,
Binh
