I was wondering if anyone has done any sort of virtualization testing
with kvm using IOMMU to improve performance of I/O and what sort of
results they've had... I currently don't have a box with IOMMU (at

Hi,
I have a Toshiba Portege M400 laptop with a core2duo T7200 CPU. It kernel

This is what I have transcribed from the screen:-

Hi,
We ran a testing against latest KVM to know its quality status.
In the testing we tried to boot guests, test basic devices of guest, and
install guests.
The commit is: 08908a44630210f97b0276f6e41ff71ec04f1308
A summary for the testing result:
Can boot most IA32/IA32e UP VMX guests, but SMP gue
