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 2 Miroslav Rezanina 2017-08-23 05:17:11 UTC 
Fix included in qemu-kvm-rhev-2.9.0-16.el7_4.5
Comment 4 FuXiangChun 2017-08-24 05:59:29 UTC 
Verified component version as below:

qemu-kvm-rhev-2.9.0-16.el7_4.5.x86_64
seabios-1.10.2-3.el7_4.1.x86_64
3.10.0-693.1.1.el7.x86_64

steps:

1.qemu-kvm cli:
/usr/libexec/qemu-kvm -M pc -cpu IvyBridge -enable-kvm -m 2G -smp 4 \

-device virtio-blk-pci,drive=system1,disable-legacy=on,disable-modern=off,id=boot_disk,bootindex=1,iommu_platform=on,ats=on -drive file=/root/rhel74-bk.qcow2,format=qcow2,if=none,id=system1 \

-vnc :1 -monitor stdio -device virtio-net-pci,netdev=hostnet1,id=net1,mac=52:54:00:7e:af:e6 -netdev tap,id=hostnet1,vhost=on -device virtio-serial-pci,id=virtio-serial0,bus=pci.0,addr=0x6 \

-chardev socket,path=/tmp/qga.sock,server,nowait,id=qga0 -device virtserialport,bus=virtio-serial0.0,chardev=qga0,id=qemu-ga0,name=org.qemu.guest_agent.0

2. Add "iommu=pt intel_iommu=on" to host kernel line

3. Add "intel_iommu=on" guest kernel line

result:

Guest works well. 

Hi Jason,
According to test result as above. Can QE verify this bug? or need to test the other device. e.g virtio-net-pci, virtio-serial-pci..
Comment 5 jason wang 2017-08-24 08:28:05 UTC 
I think you need focus on the dependency. E.g check qemu-kvm-rhev-2.9.0-16.el7_4.5 depends on seabios-bin >= 1.10.2-3.el7_4.1 and ipxe-roms-qemu >= 20170123-1.git4e85b27.el7_4.1.

Thanks

Thanks Jason, I have checked this dependency when installing qemu-kvm-rhev-2.9.0-16.el7_4.5. 

error: Failed dependencies:
	ipxe-roms-qemu >= 20170123-1.git4e85b27.el7_4.1 is needed by qemu-kvm-rhev-10:2.9.0-16.el7_4.5.x86_64
	seabios-bin >= 1.10.2-3.el7_4.1 is needed by qemu-kvm-rhev-10:2.9.0-16.el7_4.5.x86_64
	seavgabios-bin >= 1.10.2-3.el7_4.1 is needed by qemu-kvm-rhev-10:2.9.0-16.el7_4.5.x86_64
	sgabios-bin is needed by qemu-kvm-rhev-10:2.9.0-16.el7_4.5.x86_64

So,This bug is fixed.
