RE: [Xen-devel] [PATCH 0/4] HVM Virtual S3

["Yu, Ke" <ke.yu@xxxxxxxxx>]

The symptom is that: if use stdvga in config file, the windows guest
will not show "standby" in shutdown menu, which means S3 is disabled.
The following link explains why.

When use cirrus_vga, the "standby" appears in shutdown menu. However,
after "standby" is pressed, windows will pop up a dialog box, saying
default monitor driver has no power  management support, so windows
refuse to go further. 

I think Windows has strict checking on standby. it won't do standby
until the required device driver has suspend/resume support. so it is
due to qemu device emulation, not ACPI in rombios.
