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.

Comment 9 Xu Han 2014-01-27 08:16:51 UTC 
Reproduce this bug with component:
qemu-kvm-1.5.3-38.el7.x86_64

Steps:
1. Start Win2k8 R2 guest (2 Virtio SCSI disks).
e.g:# /usr/libexec/qemu-kvm -M pc -S -cpu SandyBridge -enable-kvm -m 2048 -smp 2,sockets=2,cores=1,threads=1 -no-kvm-pit-reinjection -usb -device usb-tablet,id=input0 -name zxc -uuid 990ea161-6b67-47b2-b803-19fb01e30d30 -rtc base=localtime,clock=host,driftfix=slew -device virtio-serial-pci,id=virtio-serial0,max_ports=16,vectors=0,bus=pci.0,addr=0x3 -chardev socket,id=channel1,path=/tmp/helloworld1,server,nowait -device virtserialport,chardev=channel1,name=com.redhat.rhevm.vdsm,bus=virtio-serial0.0,id=port1 -chardev socket,id=channel2,path=/tmp/helloworld2,server,nowait -device virtserialport,chardev=channel2,name=com.redhat.rhevm.vdsm,bus=virtio-serial0.0,id=port2 -drive file=/home/win2008r2-64-virtio.qcow2,if=none,id=drive-system-disk,format=qcow2,aio=native,werror=stop,rerror=stop -device virtio-scsi-pci,bus=pci.0,addr=0x4,id=scsi0 -device scsi-hd,drive=drive-system-disk,bus=scsi0.0,channel=0,scsi-id=0,lun=0,id=system-disk,bootindex=1 -netdev tap,id=hostnet0,vhost=on,script=/etc/qemu-ifup -device virtio-net-pci,netdev=hostnet0,id=virtio-net-pci0,mac=00:01:02:B6:40:11,bus=pci.0,addr=0x5 -device virtio-balloon-pci,id=ballooning,bus=pci.0,addr=0x6 -global PIIX4_PM.disable_s3=0 -global PIIX4_PM.disable_s4=0 -drive file=/home/my-data-disk.qcow2,if=none,id=drive-data-disk,format=qcow2,aio=native,werror=stop,rerror=stop -device scsi-hd,drive=drive-data-disk,bus=scsi0.0,channel=0,scsi-id=0,lun=1,id=data-disk -k en-us -boot menu=on -qmp tcp:0:4444,server,nowait -serial unix:/tmp/ttyS0,server,nowait -vnc :2 -spice disable-ticketing,port=5932 -monitor stdio
2. Start check of guest system disk (chkdsk c: /x /f /v /r).
3. Reboot guest for start checking.

Results:
qemu-kvm: hw/scsi/scsi-disk.c:287: scsi_dma_complete: Assertion `r->req.aiocb != ((void *)0)' failed.
bz1035644-cli: line 1:  8414 Aborted                 (core dumped)
------
Verify this bug with component:
qemu-kvm-1.5.3-41.el7.x86_64

Same steps as above.

Results:
after step 3, guest reboot well after chkdsk checking and it work well.

Base on these test results above, this bug has been fixed.
