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 Yihuang Yu 2020-04-28 06:22:54 UTC 
Description of problem:
Failed to create a image via "qemu-img create"

Version-Release number of selected component (if applicable):
qemu-img: qemu-img-4.2.0-19.module+el8.3.0+6423+e4cb6418.ppc64le
kernel: 4.18.0-193.13.el8.ppc64le

How reproducible:
always

Steps to Reproduce:
1. Create a qcow2 image
# qemu-img create -f qcow2 test.qcow2 10G
qemu-img: Unable to initialize gcrypt

2. Create a raw image
# qemu-img create -f raw  test.raw 10G
qemu-img: Unable to initialize gcrypt

3.

Actual results:
Failed to create image

Expected results:
Can successfully create a image

Additional info:
Comment 1 Yihuang Yu 2020-04-28 06:40:21 UTC 
I can confirm that my system has installed the libgcrypt package.

# rpm -qa | grep libgcrypt
libgcrypt-1.8.3-4.el8.ppc64le
libgcrypt-devel-1.8.3-4.el8.ppc64le

And this problem will block all qemu test.

Tested with qemu-img-4.2.0-19.module+el8.3.0+6423+e4cb6418.x86_64, hit this issue. And also can not query qemu version.

Comment 4 Yanan Fu 2020-04-28 08:22:22 UTC 
Hi Yash,

I would like to highlight this issue.
It is a regression issue with RHEL8.3.0 slow train, which block the gating test now.
Thanks!


Best regards
Yanan Fu
Comment 5 Yihuang Yu 2020-04-29 03:24:03 UTC 
A highlight is that libgcrypt provided by RHEL-8.3.0 needs to be updated. This problem depends on bug 1762765

After upgrade the libgcrypt package, qemu can work.

# rpm -qa | grep libgcrypt
libgcrypt-1.8.5-3.el8.ppc64le
libgcrypt-devel-1.8.5-3.el8.ppc64le

I think we might be able to move it to TestOnly.

Hi Yanan,

Can you try again with Yihuang's suggestion of using libgcrypt-1.8.5-3 ?
I will get someone from our team to have a look at the QEMU side as well.

Hi Yash,

Yes, libgcrypt-1.8.5-3 can work.

# rpm -qa | grep gcrypt
libgcrypt-1.8.5-3.el8.x86_64

Comment 8 Danilo de Paula 2020-04-29 15:05:19 UTC 
The fix appears to be included in the libgcrypt nightly. I triggered a new build.
Comment 9 Jeff Nelson 2020-04-29 22:19:49 UTC 
Setting testonly keyword and assigning to maintainer. If the new build works, then please move to ON_QA.
Comment 10 Yanan Fu 2020-04-30 03:50:58 UTC 
After RHEL.8.3 BaseOs 'RHEL-8.3.0-20200428.n.0', libgcrypt version already be updated from libgcrypt-1.8.3-4 to '1.8.5.2'.
This issue gone.
