Well, although I got MSI device working after a S3 resume on my box,
I just found it still lacking something. The hypervisor doesn't
automatically restore the vectors to the physical devices, but only
does that on a hypercall: physdev_restore_msi.
I guess that it works because the S3 during is short and the addr/data
are still in the device?

I uses the following:
echo 0 > /sys/class/rtc/rtc0/wakealarm
echo +20 > /sys/class/rtc/rtc0/wakealarm
echo mem > /sys/power/state
