Upstream patch series v4: https://patchwork.kernel.org/project/qemu-devel/list/?series=629626 Hi Viktor, I found that this could be a DUPLICATED with bz 1983947, I am closing it and let's follow bz 1983947 please. Sorry for any inconvenience. Regards, Qianqian *** This bug has been marked as a duplicate of bug 1983947 *** Sorry, just noticed this is for qemu not virtio-win driver, moving back now. As the patches were accepted to upstream QEMU after 7.0, moving to RHEL9.2. https://patchwork.kernel.org/project/qemu-devel/list/?series=629626 Set 'Verified:Tested,SanityOnly' as gating/tier1 test pass with the 'Fixed In Version': qemu-kvm-7.1.0-2.el9. Tested it with qemu-kvm-7.1.0-2.el9.x86_64,but dump is not produced.
