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.

Description lijin 2013-07-26 02:20:03 UTC 
Description of problem:
With build65,netkvm has only one "TestOnly" parameters:"TestOnly.RXThrottle",after downgrade to build 54,netkvm adapter has sevral "TestOnly" parameters,such as:TestOnly.DelayConnect,TestOnly.InterruptRecovery,TestOnly.Promiscuous,etc.
Then upgrade netkvm back to build 65,those "TestOnly" parameters still here,they should be removed.

Version-Release number of selected component (if applicable):
Red Hat Enterprise Linux Server release 7.0 Beta (Maipo)
kernel-3.10.0-0.rc7.64.el7.x86_64
qemu-kvm-1.5.1-2.el7.x86_64
seabios-1.7.2.2-2.el7.x86_64
virtio-win-prewhql-65

How reproducible:
100%

Steps to Reproduce:
1.boot guest with netkvm:
/usr/libexec/qemu-kvm  \
-drive file=win2k8R2.qcow2,if=none,cache=none,media=disk,format=qcow2,id=drive-scsi-0 \
-device ide-drive,drive=drive-scsi-0,id=blk0,bootindex=0 \
-global PIIX4_PM.disable_s3=0 -global PIIX4_PM.disable_s4=0 \
-usb -device usb-tablet \
-monitor stdio \
-chardev socket,id=aaaa,path=/tmp/tttt,server,nowait \
-mon chardev=aaaa,mode=readline \
-spice port=5900,disable-ticketing -vga qxl \
-chardev file,path=/root/console.log,id=serial1 \
-device isa-serial,chardev=serial1,id=s1 \
-cpu 'Penryn' -M pc \
-smp 4,cores=2,threads=1,sockets=2 -m 6G \
-enable-kvm \
-netdev tap,sndbuf=0,id=hostnet1,vhost=on,script=/etc/qemu-ifup,downscript=no -device virtio-net-pci,netdev=hostnet1,id=net1,mac=00:52:12:16:54:46,bus=pci.0,addr=0x7 \

2.in guest,device manager--->Redhat Virtio Ethernet Adapter--->Advanced,check the parameters
3.downgrade netkvm driver to build 54
device manager--->Redhat Virtio Ethernet Adapter--->Advanced,,check the parameters
4.upgrade netkvm driver to build 65
device manager--->Redhat Virtio Ethernet Adapter--->Advanced,,check the parameters

Actual results:
after step4,parameters specific in build 54 still exist,but acctually those parameters have been removed in build65.

Expected results:
after upgrade to build 65,those parameter should not shown in netkvm

Additional info:
in rhel6 host,still hit this issue.
Comment 2 Yvugenfi@redhat.com 2013-07-28 14:08:33 UTC 
Hi,

This is MS bug. If using upgrade through device manager the old registry values are not removed.

This bug should be documented.

Best regards,
Yan.
