I was happy to see the 3.0 beta with SMP support. SMP support was the last big thing I was hoping for in VB, so I am happy to see that so much effort has been put in to develop it. I know this code is experimental and I have already read a post from the developers that several bugs have already been fixed, so I will be anxiously awaiting the beta 2 release.
I am only posting this in case it can be of any help to the developers.
It took a bit of effort and research, but I was able to get a Windows XP Corporate Edition running on an Ubuntu host with 2 cores seen by the guest.
The only problem I am seeing is that even when nothing is happening on the guest, two of the four cores on my host are pegged at 100%.
Not sure what information the developers will need about this, so just tell me if I can provide any more information.

Re: SMP - High Host CPU Usage
Thanks, that answers my questions.
I am running XP SP3, but I strongly suspect it is the same problem.

Re: SMP - High Host CPU Usage -> fixed already
To update this as for the beta 2 release which came out today.
I can confirm that this is fixed as far as Windows XP SP3 is concerned.
I updated my my Ubuntu 8.04 host with beta 2 and booted my XP guest with a single core. Uninstalled and re-installed GA. Rebooted single core again and then shutdown. Enabled second core for VM and booted XP with SMP kernel. Everything came up fine.
I am looking at at the CPU usage on the host (Quad Core Dell) and I frequently see all 4 cores at or below 10% with nothing running foreground on the guest. McAfee is doing a virus scan which is pushing the CPU usage up a little, but still pretty good.
Kudos to the developers for the SMP. It was the one thing I have been waiting for in VB. I am impressed.
