It looks like that Mircosoft has defined a large number of synthetic
registers in their Hyper-v spec, so ultimately KVM should virtualize
most of these registers, so as to support the Mircosoft Enlightment,
right?

Yes, but you don't have to support all the Hyper-V features at once.
Hypervisor declares supported feature by specifying appropriate flags
in Feature identification (0x40000003) and Implementation
recommendations (0x40000004)CPUID leaves.

How to get the source of windows pv-eoi?
And what is "reference time counter", could you provide some references or code, please?

I'll be referencing to git://git.kernel.org/pub/scm/virt/kvm/kvm.git
for lazy eoi please take a look at commit:
b63cf42fd1d8c18fab71222321aaf356f63089c9
> And what is "reference time counter", could you provide some references or code, please?
Take a look at commit:
e984097b553ed2d6551c805223e4057421370f00
I also suggest reading Hypervisor Functional Specification 3.0a provided
by Microsoft and available for downloading
from http://www.microsoft.com/en-au/download/details.aspx?id=39289

Hi, Vadim
I start a vm(windows server 2008 64bit) with below qemu command, get stuck with black screen during boot stage,
no error report by qemu and kvm hypervisor, but if I remove the item "hv_vapic", then start and run the VM successfully.

Hi Zhang,
No I haven't seen such problem
Which kernel version are you running?
Does it include the latest lazy eli changes?
Btw, hv_spinlocks=0xfffffff is a pretty huge value.
Best regards,
Vadim.
