Subject: [edk2-devel] Patch OvmfPkg: Use heap memory for virtio-scsi request causing regression
Date: Thu, 1 Aug 2024 16:58:35 +0530 [thread overview]

Hello all,
After the patches [1fc55a39, b342070c] OvmfPkg: Use heap memory for
virtio-blk request/OvmfPkg: Use heap memory for virtio-scsi request got
merged, this regression is spotted.
AMD SVM/SEV/SEVES guest boot fails with OVMF packages [Ia3264/X64] built
from today's upstream edk2 repository[Head: 85fad99].
Guest boot with OVMF.fd or only with OVMF_CODE.fd gets stuck at below point:
/Divisor = 1
BaudRate/Actual (115200/115200) = 100%
PciSioSerial: Create SIO child serial device - Device Error

qemu-system-x86_64: wrong size for virtio-scsi headers <========== gets
hung/
If both OVMF code and vars file are provided the issue is not hit.
Qemu command line to recreate the issue:
/qemu-system-x86_64 \
-machine q35,kernel_irqchip=split \
-name guest=vm,debug-threads=on \
-drive if=pflash,format=raw,unit=0,file=OVMF_CODE.fd,readonly \
-cpu host \
-m 1024 \
-smp 1,cores=1,threads=1,dies=1,sockets=1 \
-kernel bzImage \
-append "root=/dev/sda rw console=ttyS0 net.ifnames=0 biosdevname=0
movable_node swiotlb=65536 " \
-drive id=disk0,file=22.04-server.qcow2,format=qcow2,if=none \
-device virtio-scsi-pci,id=scsi0,disable-legacy=on,iommu_platform=true \
-device scsi-hd,drive=disk0 \
--enable-kvm \
--nographic

Thanks,
