Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.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.

Comment 3 Miroslav Rezanina 2016-08-05 10:57:14 UTC 
Fix included in qemu-kvm-rhev-2.6.0-19.el7
Comment 5 Qianqian Zhu 2016-08-09 07:57:11 UTC 
Verified with:
qemu-kvm-rhev-2.6.0-19.el7.x86_64
kernel-3.10.0-478.el7.x86_64

Steps:
1. Launch guest:
 /usr/libexec/qemu-kvm -name linux -cpu Opteron_G5 -m 2048 -realtime mlock=off -smp 2,sockets=2,cores=1,threads=1  -device virtio-serial-pci,id=virtio-serial0,bus=pci.0,addr=0x6 -drive file=/nfsmnt/RHEL-Server-7.3-64-virtio-scsi.raw,if=none,id=scsi0,format=raw  -device virtio-scsi-pci,id=scsi0 -device scsi-disk,drive=scsi0,scsi-id=0,lun=0 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x8 -spice port=5901,disable-ticketing -vga qxl -global qxl-vga.revision=3 -netdev tap,id=hostnet0,vhost=on -device virtio-net-pci,netdev=hostnet0,id=net0,mac=3C:D9:2B:09:AB:44,bus=pci.0,addr=0x4 -monitor stdio

2. Check migrate_set_parameter command

Result:
(qemu) migrate_set_parameter cp
cpu-throttle-increment  cpu-throttle-initial
