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the product is no longer active in Red Hat Bugzilla.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.
manual retest this issue:
steps:
1.boot the guest with the virtio-win-prewhql-93 rng driver:
/usr/libexec/qemu-kvm -name 093RNGWIN732ZTS -enable-kvm -m 2G -smp 2 -uuid 61423f01-0d50-4aaf-8f63-d3c05cbf0e5c -nodefconfig -nodefaults -chardev socket,id=charmonitor,path=/tmp/093RNGWIN732ZTS,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=localtime,driftfix=slew -boot order=cd,menu=on -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 -drive file=093RNGWIN732ZTS,if=none,id=drive-ide0-0-0,format=raw,serial=mike_cao,cache=none -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 -drive file=en_windows_7_ultimate_with_sp1_x86_dvd_u_677460.iso,if=none,media=cdrom,id=drive-ide0-1-0,readonly=on,format=raw -device ide-drive,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -drive file=093RNGWIN732ZTS.vfd,if=none,id=drive-fdc0-0-0,format=raw,cache=none -global isa-fdc.driveA=drive-fdc0-0-0 -netdev tap,script=/etc/qemu-ifup,downscript=no,id=hostnet0 -device rtl8139,netdev=hostnet0,id=net0,mac=00:52:79:55:0b:21,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=isa_serial0 -device usb-tablet,id=input0 -vnc 0.0.0.0:0 -vga cirrus -object rng-random,filename=/dev/urandom,id=rng0 -device virtio-rng-pci,rng=rng0
2.downgrade the driver to virtio-win-prewhql-90
Actual results:
the driver cannot downgrade to virtio-win-prewhql-90 version successfully with the message" Windows encountered a problem installing the driver software for you device".
Expected results:
the rng driver can downgrade to virtio-win-prewhql-90 version successfully.
Retest this issue with virtio-win-prewhql-95 virtio-rng driver,the job "DF-Reinstall with IO Before and After (Certification)" can be passed successful.
