[Qemu-devel] Windows 7 guest hangs after waking up from S3
Hi, I'm using qemu with qxl (with S3/4 support. patches sent by Alon Levy). While with Windows xp guest I had no problems, Windows 7 (32 bits) hangs after S3 (it looks alive for a second, and then it gets stack).It happens only when using -net tap; with -net user, I didn't encounter a problem. Cheers, Yonit.

Please post your QEMU command-line. For sanity also please try without the QXL patches. That way we know whether this issue is related to QXL or not. Stefan

How can I test S3 without qxl? I tried using cirrus and the Sleep option
was disabled on windows 7.
I also tried the older qxl (without the patches that support s3), and
disabled off-screen surfaces (in order to allow s3 to work), and the
same problem occured.
my command line:
qemu-system-x86_64 -L pc-bios/ -m 1024 -hda img -boot c -vga qxl
-spice port=5678,disable-ticketing,streaming-video=all -net
nic,macaddr=00:1a:4a:01:00:e0,model=rtl8139 -net
tap,ifname=WIN7,script=/local/scripts/lan-ifup -nographic -global
qxl-vga.debug=1 --enable-kvm -snapshot
/local/scripts/lan-ifup

#!/bin/sh
switch=sw0
ifconfig $1 0.0.0.0 up
brctl addif ${switch} $1

-net tap vs -net user rings the bell for me. There is a known (for
me) problem with Windows S3 resume + networking. It appears that Windows
enables NIC receive interrupt before it registers NIC's interrupt handler
(only on S3 resume! On regular boot the order is different). If interrupt
arrives before NIC's interrupt handler is registered Windows hangs because
interrupt condition is never cleared in the NIC. On real hardware this
is not happening because relatively long time passes between enabling
link and receiving a first packet. With -net user guest never receives
unsolicited packet, with -net tap there are always enough broadcasts
to trigger the problem.
my command line:
qemu-system-x86_64 -L pc-bios/ -m 1024 -hda img -boot c -vga qxl
-spice port=5678,disable-ticketing,streaming-video=all -net
nic,macaddr=00:1a:4a:01:00:e0,model=rtl8139 -net
