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.

Red Hat Product Errata RHBA-2015:2513 0 normal SHIPPED_LIVE virtio-win bug fix and enhancement update 2015-11-24 13:38:38 UTC

Description Qunfang Zhang 2014-08-01 04:57:22 UTC 
Description of problem:
Boot a win2012r2 guest with 256 virtio-scsi target (1 controller, 1 LUN), and then reboot guest, qemu quit with "Guest moved used index from 10122 to 10253". Boot up with 1 scsi target, no problem. 

Version-Release number of selected component (if applicable):
kernel-2.6.32-491.el6.x86_64
qemu-kvm-0.12.1.2-2.432.el6.x86_64
virtio-win-prewhql-87 (for virtio-scsi driver)

How reproducible:
Always

Steps to Reproduce:
1. # cat 256-target.sh 
cli="/usr/libexec/qemu-kvm -machine rhel6.6.0,dump-guest-core=off -m 24G -smp 12 -cpu Westmere -vnc :10 -vga std -monitor stdio -boot menu=on -monitor unix:/tmp/monitor,server,nowait -drive file=/root/scalability/win2012-r2.qcow2,if=none,id=blk1 -device virtio-blk-pci,scsi=off,drive=blk1,id=blk-disk1,bootindex=1 -netdev tap,id=netdev1,vhost=on,script=/etc/qemu-ifup -device virtio-net-pci,netdev=netdev1,mac=02:03:04:05:06:00,id=net-pci1"
cli="$cli -device virtio-scsi-pci,id=scsi0"
count=$((${1:-1}-1))
for i in $(seq 0 $count)
do
echo $i
 cli="$cli -drive file=/home/disk/disk$i,if=none,id=disk$i"
 cli="$cli -device scsi-hd,bus=scsi0.0,drive=disk$i,id=target$i,scsi-id=$i,lun=0"
done
$cli

# sh 256-target.sh 256

2. Check whether the 256 scsi disk could be detected and used.

3. Reboot guest

Actual results:
After step 3:
(qemu) Guest moved used index from 10122 to 10253/etc/qemu-ifdown: could not launch network script

Expected results:
Guest should reboot successfully

Comment 2 Qunfang Zhang 2014-08-01 07:30:45 UTC 
This bug could be reproduced on qemu-kvm-0.12.1.2-2.432.el6.x86_64 with >= 129 virtio scsi target. 
Also test the rhel6.5 released version qemu-kvm-0.12.1.2-2.415.el6.x86_64 with 129 and 130 virtio scsi target, can not reproduce. So this should be a regression.
Comment 4 Fam Zheng 2014-08-06 00:55:13 UTC 
Qunfang, can you reproduce with 433 or later? It has a new fix on virtio-scsi (bug 1123698).

Please test with the latest build if possible.

Thanks,
Fam

Hi, Fam

I just tested qemu-kvm-0.12.1.2-2.435.el6.x86_64, this issue still exists. 

Thanks,
Qunfang
Comment 6 Qunfang Zhang 2014-08-07 03:47:51 UTC 
Can not reproduce this issue with a RHEL6.6 guest.
Comment 10 Fam Zheng 2014-08-08 08:04:43 UTC 
Changing component to RHEL 7 virtio-win since the real fix is in windows virtio-scsi driver.
Comment 11 Fam Zheng 2014-08-08 08:05:42 UTC 
Close since the bug is fixed in latest virtio-win build as comment 9.

Comment 15 Fam Zheng 2014-11-13 01:28:51 UTC 
Mike, would you please take care of this bug's erratum accordingly, or maybe close it if there is already a bug for the virtio-win update?

Thanks,
Fam

Virtio-win is something complex compared w/ other component ,it contains 3 component ,namely ,virtio-win, virtio-win-prewhql, qemu-ga-win , we ship virtio-win at last ,

Actually This bug is fixed on virtio-win-prewhql-89 build ,but the fix does not plan to included in virtio-win yet that's why we did not add the bug to advisory 

I will take care of this bug when developer make the decision (add it to erratum or propose to next release althrough it is in ON_QA/VERIFIED status
