*** Bug 2117253 has been marked as a duplicate of this bug. *** Verify this bug on qemu-kvm-6.2.0-11.module+el8.6.0+16360+9e5d914e.4.x86_64 with below tests, all pass except that hit similar bz 2106726 (I don't think we need to clone this for RHEL 8.6.z): 1. Zerocopy functional and negetive tests according to https://docs.google.com/document/d/1AINki8qsX3WX7YDam1W-NwH9J9ySBCKZnuXr6buXheY/edit; 2. All plain migration/multifd/autoconverge cases tests with zerocopy on; 3. Tier 1 migration tests with zerocopy off. Chensheng is testing zerocopy from Sap Hana side, let's wait for his test results. Verify the bug on qemu-kvm-6.2.0-11.module+el8.6.0+16360+9e5d914e.4. My test environment had some issues, so Karen O'connor help me to run the test. Her test environment is host: RHEL 8.6.z + guest 8.4 (6 TiB memory) The migration job on idle and cooled off scenario with zero-copy on works normally. In the busy scenario, there are some issues in SAP HANA benchmark process, it cause the live migration took a long time(about 20 hours), she'll rerun after it finish. I had tried the busy scenario in 3T guest with scratch build and set zero-copy on, it works normally. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory (virt:rhel and virt-devel:rhel bug fix and enhancement update), and where to find the updated files, follow the link below.
