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). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Internal Links: 846202

Description Mike Cao 2012-08-07 06:56:21 UTC 
Description of problem:


Version-Release number of selected component (if applicable):
qemu-kvm-0.12.1.2-2.302.el6.x86_64
2.6.32-294.el6.x86_64
virtio-win-prewhql-32

How reproducible:
2/2

Steps to Reproduce:
1.Start VM:
CLI:/usr/libexec/qemu-kvm -boot dc -m 4G -smp 2 -cpu Westmere -usb -device usb-tablet -netdev tap,sndbuf=0,id=hostnet2,script=/etc/qemdownscript=no -device e1000,netdev=hostnet2,mac=00:52:13:20:F5:22,bus=pci.0,addr=0x6 -uuid 7976cd92-6557-493d-86a3-7e2055a2d4cd -no-kvm-pit-reinjection -monitor stdio -rtc base=localtime,clock=host,driftfix=slew -device virtio-scsi-pci,id=bus1 -drive file=/home/win2k8-64.qcow2,if=none,media=disk,format=qcow2,rerror=stop,werror=stop,cache=writeback,aio=native,id=scsi-disk0 -device scsi-disk,drive=scsi-disk0,id=disk,bus=bus1.0,serial=miketest -vnc :3 -vga cirrus  -fda /home/virtio-win.vfd -bios /usr/share/seabios/bios-pm.bin
2.hotplug scsi disks 
eg:(qemu) __com.redhat_drive_add file=/hotadd.qcow2,werror=stop,cache=none,rerror=stop,id=drive-hotadd
(qemu) device_add virtio-scsi-pci,id=scsi-hotadd
(qemu) device_add scsi-hd,drive=drive-hotadd,id=hotadd,bus=scsi-hotadd.0
(qemu) __com.redhat_drive_add  file=/home/hotadd2.qcow2,werror=stop,cache=none,rerror=stop,id=drive-hotadd2
(qemu) device_add virtio-scsi-pci,id=scsi-hotadd2
(qemu) device_add scsi-hd,drive=drive-hotadd2,id=hotadd2,bus=scsi-hotadd2.0
3.S4 Guest 
4.Resume Guest w/ the same CLI in the step 1
  
Actual results:
Guest BSOD

Expected results:
no BSOD occurs

Additional info:
Tried w/ resume from s4 after hotunplug ,does not hit this issue .

Hi Mike,

   Did you add the second disk in your command line when you resuming guest from S4 ?

What you means is another bug :846202 .
Comment 8 Amit Shah 2013-02-21 11:07:43 UTC 
This doesn't look right: you hot-add disks, then perform S4, and resume guests w/o the hot-added disks.  This is never guaranteed to work.

Try starting qemu with command line from step 1 plus all the hot-added disks and drives, if there still is a problem, it'll be a valid bug.

What you described is a Bug refering to https://bugzilla.redhat.com/show_bug.cgi?id=846202.

This is the only way I can workaround it

You're working around a bug (for what?) with a completely wrong test case.

Closing as notabug.

But the backtrace shows sth wrong in virtio scsi driver ..

So do you mean w/o https://bugzilla.redhat.com/show_bug.cgi?id=846202 fix ,we can not say we support pm+hotplug for windows guest ,right ?

I will check it again, but what i remember from my previous investigation is that
resources allocated on hot-plug were not exactly the same as allocated statically 
during resume. So if we can specify the same resources for both events - hot-plug and resume, and Windows will not reallocate those resources - it is a Windows driver's bug.

Best regards,
Vadim.

Yes, during resume, the hot-plugged disks were not allocated.

If same resources are specified, there's another bug - bug 846202.  This one has a difference in the resource allocation during suspend and resume, which a guest isn't expected to handle.  If you believe that's not true, and is a bug, please reopen.

QE, please check again with build-88.

Closing this bug as WONTFIX for the following reasons:
- We are not going to support S3/S4 except for WHQL testing;
- There is no safe workaround for this problem, since the pci
configuration will be changed between hibernate and resume.
