I've tried out the last few versions of KVM and think it's great. It's
much easier to use and understand than Xen and performance is
surprisingly good.
One of the things I'd like to do is modify it to allow PMI generation
based on the Intel performance counter facilities. Specifically, I'd
like to
Vineet:
You probably need to provide more hardware details since it's likely
something specific to that. Ubuntu 6.10 works fine for me after
installing it with -no-kvm or on bare h/w and then booting the image
with QEMU/KVM. The msr message isn't an error; it's just stating that
the MSR_EFER and M
ers experienced in this
area.
Thanks,

Thanks for the very quick response. You guys at Qumranet are good. :)

I was messing around with using the perf counters a couple weeks ago
as a way to get deterministic exits in the instruction stream of the
guest. I used the h/w msr save/restore area to disable the counters
and save the values on guest exit and restore them on entry. I also
set up the LVT to deliver

I'm glad you found this; I thought I was going to have to repost while
actually remembering to change the subject line.

I swear this has been brought up before in this forum, but I can't
find it. I'm curious what the virtualization gurus in this forum think
of the possibilities for recursive virtualization. I know vbox claims
to support it, but I haven't come across many details on how they do
it and I don't think t
Dor,
Thanks, I realize there will certainly be a lot of work in
virtualizing them. Maybe Intel can help out with VVT-x to give a
root-root mode. ;)
Any idea at a high level how vbox does it? I will post in their forum,
but I assume somebody here has a good idea.
Thanks.

I just wanted to make the comment that the vmx_msr_index[] array
should probably have a note indicating that MSR_K6_STAR is always
assumed to be the last entry in the array by setup_msrs(). This just
caused me some trouble when I updated to the latest code.
Thanks,
Casey
