Description Sibiao Luo 2013-01-07 03:15:09 UTC 
Description of problem:
boot rhel7 guest on rhel7 host, but fail to do S3/S4. 
BTW, 
1.it can do S3/S4 successfully when boot rhel6.4 guest on the rhel7 host with the same qemu-kvm command line.
2.it can do S3/S4 successfully in rhel7 host.

Version-Release number of selected component (if applicable):
host info:
# uname -r && rpm -q qemu-kvm
3.6.0-0.29.el7.x86_64
qemu-kvm-1.2.0-21.el7.x86_64
gust info:
# uname -r
3.6.0-0.29.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1.boot rhel7 guest on rhel rhel7 host with '-global PIIX4_PM.disable_s3=0 -global PIIX4_PM.disable_s4=0'.
2.cat the /sys/power/state in guest.
# cat /sys/power/state 
mem disk
3.do S3/S4 in guest.
# pm-suspend/pm-hibernate

Actual results:
after step 3, cannot do S3/S4.
- for S4, the guest kernel log output as following:
# nc -U /tmp/ttyS0 
[  OK  ] Started Show Plymouth Boot Screen.
[  OK  ] Reached target Basic System.

Expected results:
it can do S3/S4 successfully when boot rhel7 guest on rhel rhel7 host.

Comment 3 Qian Guo 2013-02-26 09:35:52 UTC 
In my test, this bug just occurs when using "-vga cirrus", and the S4 works well.

Version-Release number of selected component (if applicable):
host info:
# uname -r && rpm -q qemu-kvm
3.8.0-0.37.el7.x86_64
qemu-kvm-1.3.0-5.el7.x86_64

guest info:
# uname -r
3.6.0-0.36.el7.x86_64

How reproducible:
100%

Steps 
1.boot rhel7 guest 
2.cat the /sys/power/state in guest.
# cat /sys/power/state 
mem disk
3.do S3/S4 in guest.
# pm-suspend/pm-hibernate

Actual results:

S3 is not work and S4 works well.

I test w/ cirrus, qxl and std, just cirrus hit this problem, so I think it is a bug related w/ cirrus.

My guest cli list below:

Comment 4 Chao Yang 2013-03-18 09:43:55 UTC 
Here is an update on s3/s4 issue tested with qemu-kvm-1.4.0-1.el7.x86_64, guest kernel 3.8.0-0.40.el7.x86_64, qxl in cli. But my case is with VFs assigned. The test result is: cannot suspend guest to memory or disk. 

Suspend to disk:
---------------
Steps:
1. echo disk to /sys/power/state
Result:
qemu-kvm didn't quit.
 
from guest dmesg:
[   59.612586] PM: Syncing filesystems ... done.
[   59.619736] Freezing user space processes ... (elapsed 0.02 seconds) done.
[   59.645113] PM: Preallocating image memory... done (allocated 252897 pages)
[   59.881745] PM: Allocated 1011588 kbytes in 0.23 seconds (4398.20 MB/s)

[   59.896313] Suspending console(s) (use no_console_suspend to debug)

Suspend to memory:
-----------------
Steps:
1. echo mem to /sys/power/state
2. (qemu) info status
VM status: paused (suspended)
3. (qemu) system_wakeup 
(qemu) main_channel_handle_parsed: agent start

(qemu) info status
VM status: running

Result:
qemu-kvm didn't resume correctly. It hung at screen "Bochs VBE Display Adapter enabled". I got lots of:
(qemu) __spice_char_device_write_buffer_get: internal buf is not available
__spice_char_device_write_buffer_get: internal buf is not available
__spice_char_device_write_buffer_get: internal buf is not available
....

from guest dmesg:
[  152.650585] PM: Syncing filesystems ... done.
[  153.612251] Freezing user space processes ... (elapsed 0.02 seconds) done.

HI,chayang
  I have tried to test use your CLI but remove vfio-pci device. Hit another bug:

Bug 920017 - rhel7 guest will call trace after resume from S3/S4 in rhel7 host 
https://bugzilla.redhat.com/show_bug.cgi?id=920017


So i think maybe vfio-pci device trigger the problem  you hit.

MY Test:
Host:
# uname -r
3.8.0-0.40.el7.x86_64
# rpm -q qemu-kvm
qemu-kvm-1.4.0-1.el7.x86_64

Guest:

Comment 7 Qian Guo 2013-04-24 10:15:30 UTC 
Test w/ vnc$std when using rhel7 guest hit following issue:succeed change to S3 state when do 'pm-suspend' inside guest, 

Components:
# uname -r
3.9.0-0.rc7.53.el7.x86_64

# rpm -q qemu-kvm
qemu-kvm-1.4.0-2.1.el7.x86_64


Steps:
1.Guest cli:
# /usr/libexec/qemu-kvm -cpu host -m 4G -smp 4,sockets=1,cores=4,threads=1 -M pc -enable-kvm  -name win2012  -drive file=/home/rhel7cp2.qcow3,if=none,format=qcow2,werror=stop,rerror=stop,media=disk,id=drive-scsi0-disk0 -device virtio-scsi-pci,id=scsi0,addr=0x4 -device scsi-hd,scsi-id=0,lun=0,bus=scsi0.0,drive=drive-scsi0-disk0,id=virtio-disk0 -nodefaults -nodefconfig -monitor stdio   -netdev tap,id=bd,script=/etc/qemu-ifup,ifname=qiguo1 -device e1000,netdev=bd,mac=54:52:1a:46:0b:02,id=vnic1  -vnc :20 -vga std  -boot menu=on -device virtio-balloon-pci,id=balloon1

1.Do S3 inside guest:
(qemu) info status
VM status: paused (suspended)

2.Press keyboard or do 'system-wakeup'

(qemu) info status
VM status: running

Results:
From the vnc window of guest, still in darksreen, but if I try to access tty2 (send key :ctrl+alt+f2), succeed, and then send key (ctrl+alt+f1), resumes well.

Addional info:
not hit this issue w/ qxl 

and like comment #6 , could not do S3 when using cirrus.
Comment 8 langfang 2013-07-05 08:23:12 UTC

2. do S3 and resume
3. system_reset and do S4 and resume.

Results:
After 2, guest can not resume from S3, windows GUI hang, please ref attachment picture. But ping guest is successful. 
After 3, qemu-kvm quit with the following message:

Please retest with RHEL-7.1 (both host+guest), cirrus s3 should be fixed there.

I tried the latest rhel7.1(guest/host) with cirrus vga for repeat tree times S3 which can resume successfully without any problem.

# /usr/libexec/qemu-kvm -M pc...-vnc :1 -vga cirrus

host info:
# uname -r && rpm -q qemu-kvm
3.10.0-219.el7.x86_64
qemu-kvm-1.5.3-84.el7.x86_64
guest info:
# uname -r
3.10.0-219.el7.x86_64

Best Regards,
sluo
