I'd like to perform a bisect to figure out what commit caused this regression. We need to identify the earliest kernel where the issue started happening as well as the latest kernel that did not have this issue.
Can you test the following kernels and report back? We are looking for the first kernel version that exhibits this bug: 4.5 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.5-wily/ 4.6 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6-yakkety/ 4.7 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7/ 4.8-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8-rc1/ You don't have to test every kernel, just up until the kernel that first has this bug.

The only thing I have changed between the 2 setups is adding <driver name='kvm'/> to the network definition as the now default vfio also failed with qemu-system-x86_64: vfio_dma_map(0x55f1c4f8bb00, 0xfe000000, 0x4000, 0x7fa687700000) = -14 (Bad address) qemu: hardware error: vfio: DMA mapping failed, unable to continue If I am doing something wrong I apologise, this is my first bug report and I'm still relatively new to Linux.
