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.

How reproducible:
------------------
100%


Steps to Reproduce:
--------------------
boot guest:
/usr/libexec/qemu-kvm -monitor stdio -cpu qemu64,+sse2 -smp 2,cores=1,threads=4,sockets=2 -m 2G -drive file=/home/win2008r2-64-virtio.qcow2,if=none,id=drive-virtio-disk1,media=disk,cache=none,format=qcow2,werror=stop,bootindex=0 -device virtio-blk-pci,bus=pci.0,addr=0x3,drive=drive-virtio-disk1,id=virtio-disk1 -boot menu=on -M rhel6.2.0 -balloon none -spice port=8000,disable-ticketing -vga qxl -netdev tap,id=id10,script=/etc/qemu-ifup -device virtio-net-pci,netdev=id10,mac=9a:fe:9d:9b:24:10,id=ndev10,bus=pci.0,addr=0x5 -device usb-ehci,id=ehci -device usb-host,hostbus=2,hostaddr=2,id=hostdev1,bus=ehci.0,port=1


Actual results:
------------------

      is enabled and HC is enabled
ehci: PERIODIC list base register set while periodic schedule
      is enabled and HC is enabled
ehci: PERIODIC list base register set while periodic schedule

Comment 3 juzhang 2011-11-09 01:04:47 UTC 
FYI,I just hit this issue with windows guests.linux guests works well
Comment 4 Xiaomei Gao 2011-11-24 05:24:39 UTC 
also, i boot a guest with 1.0 controller:
/usr/libexec/qemu-kvm -usb -device usb-host,hostbus=2,hostaddr=2,id=hostdev1

dmesg on host:
JBD2: I/O error detected when updating journal superblock for sdb1-8.
Aborting journal on device sdb1-8.
JBD2: I/O error detected when updating journal superblock for sdb1-8.
journal commit I/O error
EXT4-fs error (device sdb1): ext4_put_super: Couldn't clean up the journal

Comment 5 Gerd Hoffmann 2012-02-14 16:58:16 UTC 
Win7 guest works fine, on WinXP the issue reproduces.
Will look into it.
