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.

Red Hat Product Errata RHSA-2017:0621 0 normal SHIPPED_LIVE Moderate: qemu-kvm security and bug fix update 2017-03-21 12:28:31 UTC

Comment 1 weliao 2016-01-21 10:12:29 UTC 
retested on rhel6.7 host version:

2.6.32-573.el6.x86_64
qemu-kvm-0.12.1.2-2.479.el6.x86_64


also had this issue, so this not a regression bug.
Comment 3 weliao 2016-01-22 03:00:17 UTC 
retested rhel6.7.Z host version:
2.6.32-573.19.1.el6.x86_64
qemu-kvm-0.12.1.2-2.479.el6_7.3.x86_64

also had this issue.
Comment 4 Vlad Yasevich 2016-03-07 13:25:04 UTC 
Moving to 6.9.  Not critical.
Comment 5 Yash Mankad 2016-12-14 19:13:41 UTC 
Fix included in qemu-kvm-0.12.1.2-2.498.el6
Comment 7 weliao 2016-12-19 03:32:34 UTC 
Reproduced this bug in following versions:
Host:
    2.6.32-672.el6.x86_64
    qemu-kvm-0.12.1.2-2.496.el6.x86_64
Guest:
    2.6.32-671.el6.x86_64

Steps to Reproduce:
1.Boot a guest with(e1000/rtl8139):
-device e1000,mac=9a:60:61:62:63:64,id=idpBvu3g,netdev=idTjoQTn,bus=pci.0,addr=05 \
-netdev tap,id=idTjoQTn

2.Change mac address in guest
#ip link set eth0 addr 9a:60:61:62:63:68

3.Check the mac address in guest and qemu monitor
Before Mac change:
(qemu) info network 
Devices not on any VLAN:
  idTjoQTn: ifname=tap0,script=/etc/qemu-ifup,downscript=/etc/qemu-ifdown peer=idpBvu3g
  idpBvu3g: model=e1000,macaddr=9a:60:61:62:63:64 peer=idTjoQTn
After Mac change:
(qemu) info network 
Devices not on any VLAN:
  idTjoQTn: ifname=tap0,script=/etc/qemu-ifup,downscript=/etc/qemu-ifdown peer=idpBvu3g
  idpBvu3g: model=e1000,macaddr=9a:60:61:62:63:64 peer=idTjoQTn

The same result with rtl8139 NIC.

-----------------------------------------------------------------------------
Verify this bug in following versions:
Host:
    2.6.32-672.el6.x86_64
    qemu-kvm-0.12.1.2-2.498.el6.x86_64
Guest:
    2.6.32-671.el6.x86_64

The same test steps:
Step3 results:
Before Mac change:
(qemu) info network 
Devices not on any VLAN:
  idTjoQTn: ifname=tap0,script=/etc/qemu-ifup,downscript=/etc/qemu-ifdown peer=idpBvu3g
  idpBvu3g: model=e1000,macaddr=9a:60:61:62:63:64 peer=idTjoQTn
After Mac change:
(qemu) info network 
Devices not on any VLAN:
  idTjoQTn: ifname=tap0,script=/etc/qemu-ifup,downscript=/etc/qemu-ifdown peer=idpBvu3g
  idpBvu3g: model=e1000,macaddr=9a:60:61:62:63:68 peer=idTjoQTn

Mac address can be change in qemu monitor, so this bug fixed well.
