In my case, I run a ping to the host (10.0.2.2) while the s4 suspend/resume operations are performed. Complete dmesg, for all 3 invocations of the guest. First one boots, starts ping, starts s4. Second one starts s4 after confirming ping is working fine. Third one just stays there, spinning. $ ./x86_64-softmmu/qemu-system-x86_64 -kernel ~/src/linux/arch/x86/boot/bzImage -append 'root=/dev/vda1 console=tty0 console=ttyS0 no_console_suspend' -drive file=/guests/f14-suspend.qcow2,if=none,id=dr0 -device virtio-blk-pci,drive=dr0 -net nic,model=virtio -net user -serial stdio -enable-kvm -m 512 -cpu host -smp 4 [ 0.000000] Initializing cgroup subsys cpu [ 0.000000] Linux version 3.3.0-rc2+ (amit@xxxxxxxxxxxxxxx) (gcc version 4.6.2 20111027 (Red Hat 4.6.2-1) (GCC) ) #295 SMP PREEMPT Fri Feb 10 18:39:48 IST 2012 [ 0.000000] Command line: root=/dev/vda1 console=tty0 console=ttyS0 no_console_suspend [ 0.000000] BIOS-provided physical RAM map: [ 0.000000] BIOS-e820: 0000000000000000 - 000000000009dc00 (usable) [ 0.000000] BIOS-e820: 000000000009dc00 - 00000000000a0000 (reserved) [ 0.000000] BIOS-e820: 00000000000f0000 - 0000000000100000 (reserved) [ 0.000000] BIOS-e820: 0000000000100000 - 000000001fffd000 (usable) [ 0.000000] BIOS-e820: 000000001fffd000 - 0000000020000000 (reserved) [ 0.000000] BIOS-e820: 00000000feffc000 - 00000000ff000000 (reserved) [ 0.000000] BIOS-e820: 00000000fffc0000 - 0000000100000000 (reserved) [ 0.000000] NX (Execute Disable) protection: active [ 0.000000] DMI 2.4 present.
