I have a very similar setup with a Sapphire RX Vega 56 and also observing this lockup. I am using an unpatched Debian 4.19.0. Qemu 3.1.0. Libvirt 5.0.0. A single host core is pegged at 100%. I've attached my XML too. $ cat /sys/module/kvm/parameters/ignore_msrs Y I cannot find any logs indicating any problems... $ sudo journalctl | grep kvm Mar 28 20:35:52 socrates kernel: Command line: BOOT_IMAGE=/boot/vmlinuz-4.19.0-4-amd64 root=/dev/mapper/VolGroup00-lvdebian ro iommu=pt amd_iommu=force_isolation rd.driver.pre=vfio-pci hugepagesz=1GB hugepages=16 vfio_iommu_type1.allow_unsafe_interrupts=1 kvm.ignore_msrs=1 Mar 28 20:35:52 socrates kernel: Kernel command line: BOOT_IMAGE=/boot/vmlinuz-4.19.0-4-amd64 root=/dev/mapper/VolGroup00-lvdebian ro iommu=pt amd_iommu=force_isolation rd.driver.pre=vfio-pci hugepagesz=1GB hugepages=16 vfio_iommu_type1.allow_unsafe_interrupts=1 kvm.ignore_msrs=1 Mar 28 20:35:52 socrates kernel: kvm: Nested Virtualization enabled Mar 28 20:35:52 socrates kernel: kvm: Nested Paging enabled $ sudo journalctl | grep msrs Mar 28 20:35:52 socrates kernel: Command line: BOOT_IMAGE=/boot/vmlinuz-4.19.0-4-amd64 root=/dev/mapper/VolGroup00-lvdebian ro iommu=pt amd_iommu=force_isolation rd.driver.pre=vfio-pci hugepagesz=1GB hugepages=16 vfio_iommu_type1.allow_unsafe_interrupts=1 kvm.ignore_msrs=1 Mar 28 20:35:52 socrates kernel: Kernel command line: BOOT_IMAGE=/boot/vmlinuz-4.19.0-4-amd64 root=/dev/mapper/VolGroup00-lvdebian ro iommu=pt amd_iommu=force_isolation rd.driver.pre=vfio-pci hugepagesz=1GB hugepages=16 vfio_iommu_type1.allow_unsafe_interrupts=1 kvm.ignore_msrs=1
