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.

Fixed In Version:
Doc Type: Bug Fix
Doc Text:
In the previous version all inflate/deflate request were performed by workitems, which makes it possible to execute inflate/deflate requests simultaneously with PnP and Power management handlers. The problem was fixed by changing design from work items to dedicated thread, and processing PnP and PM requests only after completion all other pending requests.

Description of problem:

win7 guest crash when I disble/enable virtIO balloon device during enlarging/evicting memory and at same time qemu monitor window get a message said "(qemu) virtio_ioport_write: unexpected address 0x13 value 0x1"

Version-Release number of selected component (if applicable):

virtio-win-1.5.2-1.el6.noarch

How reproducible: (reproduce ratio is about 60% )

step 1:

Bootup windows7 guest with balloon device enabled , command like below:

/usr/libexec/qemu-kvm -M rhel6.3.0 -cpu Penryn -smp 2,sockets=2,cores=1,threads=1 -m 4G -enable-kvm -uuid `uuidgen` -boot order=dnc,once=d  -drive file=/usr/share/virtio-win/virtio-win-1.5.2.iso,if=none,media=cdrom,id=drive-ide0-1-0,readonly=on,format=raw -device ide-drive,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0,bootindex=1 -spice port=5904,disable-ticketing -k en-us -rtc base=localtime,driftfix=slew -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 -device usb-tablet,id=input0 -drive file=/root/win7.qcow2,if=none,id=drive-virtio-disk0,format=qcow2,serial=yzWaibVh,cache=none,werror=stop,rerror=stop,aio=native -device ide-drive,drive=drive-virtio-disk0,id=virtio-disk0 -netdev tap,id=hostnet0,vhost=on -device virtio-net-pci,netdev=hostnet0,id=net0,mac=9a:1b:69:1a:e5:5c,bus=pci.0,addr=0x5,bootindex=3 -monitor stdio -device virtio-balloon-pci,id=balloon1,bus=pci.0,addr=0x7 -qmp tcp:0:4444,server,nowait

step 2:

Open "Device manager" window and install virtIO balloon device driver from CD-room in guest

step 3:

Execute info balloon in qemu monitor window

step 4:

Disabled virtIO balloon device in "Device Manager"(guest side)

step 5:

Execute "balloon 600" evicting memory in qemu monitor window

step 6:
Enabled virtIO balloon device in windows "Device Manager" window

step 7:

Disable virtIO balloon device in windows "Device Manager" window during evicting memory

step 8:
resize balloon value in qemu monitor window with "balloon 2048"

repeat step5 - step8 (most of times , guest crash in step4 or step8)

Actual results:

sometimes, guest crashed


Expected results:

guest works fine, no crash happened


Additional info:

qemu-kvm-0.12.1.2-2.295.el6.x86_64

Comment 1 Amit Shah 2012-06-13 10:53:05 UTC 
> (qemu) virtio_ioport_write: unexpected address 0x13 value 0x1"

This means the driver is trying to write to a read-only address, VIRTIO_PCI_ISR.  Linux guests never write to this address.  Looks like the Windows PCI driver does, and that's a bug.
Comment 4 Ronen Hod 2012-09-02 08:35:13 UTC 
Postponed to RHEL6.5, due to capacity constraints, and under the assumption that no customer is using virtio-win ballooning.
Comment 5 Vadim Rozenfeld 2012-09-09 14:33:35 UTC 
please recheck with the latest driver from build 35
http://download.devel.redhat.com/brewroot/packages/virtio-win-prewhql/0.1/35/win/virtio-win-prewhql-0.1.zip

  Reproduced this issue on virtio-win-1.5.2
  Verified the bug on virtio-win-prewhql-0.1-35

  Start guest,
  /usr/libexec/qemu-kvm -cpu Penryn -smp 2 -m 4G -enable-kvm -uuid `uuidgen` -spice port=5931,disable-ticketing -k en-us -rtc base=localtime,driftfix=slew -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 -device usb-tablet,id=input0 -drive file=/home/win7-64-725-active.raw,if=none,id=drive-virtio-disk0,format=raw,serial=yzWaibVh,cache=none,werror=stop,rerror=stop,aio=native -device ide-drive,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 -netdev tap,id=hostnet0,vhost=on -device e1000,netdev=hostnet0,id=net0,mac=9a:1b:69:1a:e5:5c,bus=pci.0,addr=0x5,bootindex=3 -monitor stdio -device virtio-balloon-pci,id=balloon1,bus=pci.0,addr=0x7 -qmp tcp:0:4444,server,nowait
 
 Steps,
 repeat steps 5-8 from comments 0

Actual Results:
on virtio-win-1.5.2 ,guest got BSOD.
on virtio-win-prewhql-0.1-35,guest works well without error.

Based on above ,this issue has been fixed already ,move status to VERIFIED.
