RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit).

--------------------------------------------------------------
qemu-kvm-1.4.0-1.el7.x86_64

Actual results:
------------------
in guest, s4 fails to work, remove xhci controller and usb-storage attached on it in cmd, s4 works correctly.
Comment 2 Gerd Hoffmann 2013-05-14 14:37:26 UTC 
Please retest with qemu 1.5, might be fixed meanwhile.

In case it still fails:  What happens exactly?  Guest refuses to suspend?  Guest fails to resume?  qemu crashes?  Something else?

Is the usb-storage needed to trigger or do you see failures with xhci alone too?
Comment 3 juzhang 2013-05-16 02:33:18 UTC 
Hi Shu,

Please retest once our internal build which is based on qemu.15.
Comment 4 Shaolong Hu 2013-05-28 09:34:33 UTC 
Test with qemu-kvm-1.5.0-2.el7.x86_64 and kernel 3.10.0-0.rc2.57.el7.x86_64 both in guest and host, this time S3/S4 won't even work without xhci, it's hard to tell what's the problem since there are tens of S3/S4 bugs, i will re-test this one after S3/S4 works again, keeps the needinfo set.
Comment 5 Gerd Hoffmann 2013-11-05 12:43:09 UTC 
Ping, s3 seems to work meanwhile (at least with "-M pc").
Please see comment #2 and retest.
Comment 7 Gerd Hoffmann 2014-05-23 08:44:33 UTC 
possibly related: upstream commit f1f8bc218a422081f36f0b325b3de5e6a5078b74

Hi Shu,

Can you have a try and update the testing result in the bz?

Best Regards,

Tried with command line in comment0, with:

guest fails to recover from S4 


without Usb related command line, guest recovers from S4 correctly.
Comment 11 Shaolong Hu 2014-07-04 09:03:33 UTC 
Version:

qemu-kvm-rhev-1.5.3-60.el7ev.x86_64
Comment 12 Gerd Hoffmann 2014-07-04 11:35:07 UTC 
Please retest with this test build:
http://people.redhat.com/ghoffman/bz1103193/

(probably doesn't change anything, test build has a bunch of usb fixes but
 nothing s4 related, but who knows, doesn't hurt to check ...)

What does "fails to recover" mean exactly?
Guest dead?  Only USB broken?  Something else?

Boot guest again, guest restarts instead of recovering from hibernate.
