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the product is no longer active in Red Hat Bugzilla.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.

I run a virtual machine by executing the following command:
/usr/libexec/qemu-kvm -drive id=root_drive,file=root,if=ide,media=disk -drive id=volume_drive,file=volume,if=virtio,media=disk -device virtio-blk-pci,drive=volume_drive,id=volume
On RHEL 6.0 with qemu-kvm-0.12.1.2-2.113.el6_0.8 it works fine, but on RHEL 6.1 with qemu-kvm-0.12.1.2-2.160.el6 it fails with the following output:
qemu-kvm: -drive id=volume_drive,file=volume,if=virtio,media=disk: Property 'virtio-blk-pci.drive' can't take value 'volume_drive', it's in use
Am I misunderstanding something or device attaching is really broken?

You CML probably wrong
you can't define interface two times
-drive id=volume_drive,file=volume,*if=virtio*,media=disk /first time/
-device virtio-blk-pci,drive=volume_drive,id=volume /second time/
Would you please try the following two methods
1.Use -drive&-device
/usr/libexec/qemu-kvm
-drive id=root_drive,file=root,if=none,media=disk
-device ide-drive,drive=root_drive
-drive id=volume_drive,file=volume,if=none,media=disk
-device virtio-blk-pci,drive=volume_drive,id=volume
2.Just use -drive option
#/usr/libexec/qemu-kvm -drive id=root_drive,file=root,if=ide,media=disk -drive
id=volume_drive,file=volume,if=virtio,media=disk
-drive
file=/root/zhangjunyi/rhel5.6-virtio-64.qcow2,if=none,id=test,cache=none,format=qcow2,werror=stop,rerror=stop
-device virtio-blk-pci,drive=test
