We (Qumranet) have Linux paravirtual network support working, but not
ready for general consumption yet.
Hmm, is the general consumption of the network support a matter of
weeks, or months

When I start my Windows VM with -no-kvm, it seems to boot much more
quickly than without. Also there's a long period, right after the VM
changes its screen resolution from the 640x480 used for Windows' boot
screen to 1280x1024, where the VM's screen goes all white. Is this
all normal?

You probably have acpi enabled in Windows. This causes massive
slowdowns in kvm; the real fix will unfortunately require you to upgrade
your hardware.
There is a workaround:

Ah, ok -- I misunderstood the whole thing. The way to avoid the race is
to disable interrupts before entering the guest. This way the IPI is
delayed until you enter guest mode:

the pv block driver is in Ingo's -rt tree if you want to look at it.
Glad to know you made it to his tree :)
When do you think it can be integrated to mainline kvm?
the biggest gap left is how to associate the virtual file with the host.
Once I've figured that it's ready to go imo.

This is just a (probably silly) idea I had the other day. Currently, the
