Fix virtio problem on s390x with raw DASD devices (!152) · Merge requests · Red Hat / centos-stream / src / kernel / centos-stream-9

Thomas Huth requested to merge thuth/kernel-cs-9:bz2008401 into main Nov 16, 2021

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2008401

Using raw DASD devices as a backend for virtio-blk devices in the guest is currently not possible with the RHEL9 kernel. This patch fixes this issue. Tested by installing the patched kernel in an s390x KVM guest and checking that a virtio-blk disk with a raw DASD backend works again as expected.
