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 of problem:
When using the RHEL-7.7-20190420.n.0-Server-ppc64le-dvd1.iso install guest, it will display ":Warning /dev/root does not exist"
But when I use RHEL-7.7-20190408.n.0-Server-ppc64le-dvd1.iso, I can install the guest normally.

Version-Release number of selected component (if applicable):
  kernel version:3.10.0-1040.el7.ppc64le
  qemu-kvm version:qemu-kvm-rhev-2.12.0-26.el7

Normal installation


Additional info:

The same problem occurs in the following versions：
1. kernel version:4.18.0-80.17.el8.ppc64le
   qemu-kvm version:qemu-kvm-2.12.0-63.module+el8+2833+c7d6d092

2. kernel version:4.18.0-80.17.el8.ppc64le
   qemu-kvm version:qemu-kvm-4.0.0-rc4
Comment 2 Zhenyu Zhang 2019-04-25 08:26:05 UTC 
Additional info:
We found guest installation was a failure， in all trees of RHEL-7.7-20190409.n.0-Server-ppc64le-dvd1.iso -----RHEL-7.7-20190424.0.iso  
But when I use RHEL-7.7-20190408.n.0-Server-ppc64le-dvd1.iso, I can install the guest normally.
Comment 3 Gu Nini 2019-04-25 08:31:26 UTC 
Please note the bug should be not ppc specific since kernel qe found a similar bz1702867.

It works well for x86.

Does this setup use iscsi?

> Does this setup use iscsi?

Hi Lukáš,
Usually, we use the disk from LocalFS, ISO file from nfs/LocalFS to test this scenario.

In addition, I can successfully launch the installation GUI when I add "-kernel" and "-initrd"

-kernel 'vmlinuz'  \
-initrd 'initrd.img'  \

Comment 9 Zhenyu Zhang 2019-04-30 03:18:08 UTC 
We found that the compose version of RHEL-7.7-20190424.0-Server-ppc64le has the same problem.
But download these two files 'vmlinuz'and 'initrd.img' to the host,add "-kernel" and "-initrd"to the command line to install successfully
