Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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.
---Problem Description---
When guest OS is started using qemu-kvm command appended with "-usb usbdevice
host:<vendorid>:<productid>", the USB passthrough device is not made available to the guest OS.
Though qemu-kvm command starts guest OS without any errors, inside the guest OS, "lsusb" command is
not listing the passthrough device.
Guest OS : SLES11 SP1 64 bit
---uname output---
Linux hostname.in.ibm.com 2.6.32-118.el6.x86_64 #1 SMP Tue Feb 22 11:15:55 EST 2011 x86_64 x86_64
x86_64 GNU/Linux
Machine Type = HS22
---Debugger---
A debugger is not configured
---Steps to Reproduce---
Steps:
1. Started qemu-kvm command appending "-usb usbdevice host:<vendorid>:<productid>".
command: /usr/libexec/qemu-kvm -hda ../images/SLES11-SP1-64.raw -m 512 -vnc :9 -usb usbdevice
host:04b3:4010 -net nic -net tap,script=../scripts/qemu-ifup
2. Once the guest is started, logged in to the guest and run "lsusb".
It is not listing the passthrough device.
