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 Laurent Vivier 2017-10-02 14:46:29 UTC
Description of problem:

An easy shortcut to boot from an install ISO is to use "-cdrom" but since qemu-kvm-rhev-2.9.0 it is broken

Version-Release number of selected component (if applicable):

qemu-kvm-rhev-2.10.0-1.el7

How reproducible:

100%

Steps to Reproduce:
1.  /usr/libexec/qemu-kvm -cdrom /home/isos/RHEL-7.3-20161019.0-Server-ppc64-dvd1.iso

Actual results:

qemu-kvm: -cdrom /home/isos/RHEL-7.3-20161019.0-Server-ppc64-dvd1.iso: machine type does not support if=scsi,bus=0,unit=2

Expected results:

The guest should start and boots from the CDROM ISO.

Additional info:

The problem has been introduced by a downstream only commit:

39372c8 scsi: Disable deprecated implicit SCSI HBA creation more cleanly
BZ 971799

Comment 3 aihua liang 2017-11-01 06:02:38 UTC
x86 don't hit this issue.

Test version:
  kernel version: 3.10.0-760.el7.x86_64
  qemu-kvm-rhev version:qemu-kvm-rhev-2.10.0-3.el7.x86_64

Comment 5 Markus Armbruster 2017-11-28 12:38:08 UTC
This bug only affects machine types where -drive defaults to if=scsi.  x86 defaults to if=ide.

Comment 8 Miroslav Rezanina 2017-11-30 16:54:03 UTC
Fix included in qemu-kvm-rhev-2.10.0-10.el7

Reproduction:
[root@ibm-p8-kvm-02-qe yhong]# rpm -qa | grep qemu
ipxe-roms-qemu-20170123-1.git4e85b27.el7_4.1.noarch

[root@ibm-p8-kvm-02-qe yhong]# 
[root@ibm-p8-kvm-02-qe yhong]# /usr/libexec/qemu-kvm -cdrom ./iso/RHEL-7.4-20170711.0-Server-ppc64le-dvd1.iso
qemu-kvm: -cdrom ./iso/RHEL-7.4-20170711.0-Server-ppc64le-dvd1.iso: machine type does not support if=scsi,bus=0,unit=2

Verification:
[root@ibm-p8-kvm-02-qe yhong]# rpm -qa | grep qemu
ipxe-roms-qemu-20170123-1.git4e85b27.el7_4.1.noarch

[root@ibm-p8-kvm-02-qe yhong]# 
[root@ibm-p8-kvm-02-qe yhong]# /usr/libexec/qemu-kvm -cdrom ./iso/RHEL-7.4-20170711.0-Server-ppc64le-dvd1.iso
VNC server running on ::1:5900

Then boot it with cli:
eg:
[root@ibm-p8-kvm-02-qe command]# cat install.sh 
/usr/libexec/qemu-kvm \
-name 'guest' \
-machine pseries-rhel7.4.0 \
-m 8G \
-nodefaults \

-boot order=cdn,once=d,menu=off,strict=off  \
-device nec-usb-xhci,id=xhci0 \
-device usb-tablet,id=usb-tablet0 \
-device usb-kbd,id=usb-kbd0 \
-device VGA,id=vga0 \
-chardev socket,id=qmp_id_qmpmonitor,path=/var/tmp/qmp-cmd-monitor-yhong,server,nowait \
-mon chardev=qmp_id_qmpmonitor,mode=control  \
-enable-kvm \
-device virtio-scsi-pci,bus=pci.0,addr=0x06,id=scsi-pci-0 \
-drive file=/root/test_home/yhong/image/install-sys-disk-20G.qcow2,snapshot=off,format=qcow2,if=none,aio=threads,cache=none,media=disk,werror=stop,rerror=stop,id=drive-0 \
-device scsi-hd,bus=scsi-pci-0.0,id=scsi-hd-0,drive=drive-0,channel=0,scsi-id=0,lun=0 \
-netdev tap,id=hostnet0,script=/etc/qemu-ifup \
-device virtio-net-pci,netdev=hostnet0,id=virtio-net-pci0,mac=40:f2:e9:5d:9c:03 \
-qmp tcp:0:3000,server,nowait \
-chardev socket,id=serial_id_serial,path=/var/tmp/serial-yhong,server,nowait \
-device spapr-vty,reg=0x30000000,chardev=serial_id_serial \
-monitor stdio \
-cdrom ../iso/RHEL-7.4-20170711.0-Server-ppc64le-dvd1.iso \
-vnc :30

Actual result:
Guest could boot up and install so from cdrom successfully.

So this bug is fixed with qemu-kvm-rhev-2.10.0-10.el7.ppc64le. Change the status to VERIFIED.
Thanks.
