Bug#1102914:

[Milan Broz <gmazyland@gmail.com>]

Hi,

we have the same issue with 6.1.133-1 (previous 6.1.129-1 works fine).

We use passthrough of NVMe device, VM start now fails with

qemu-system-x86_64: -device {"driver":"vfio-pci","host":"0000:03:00.0","id":"hostdev0","bus":"pci.3","addr":"0x0"}: VFIO_MAP_DMA failed: Cannot allocate memory
qemu-system-x86_64: -device {"driver":"vfio-pci","host":"0000:03:00.0","id":"hostdev0","bus":"pci.3","addr":"0x0"}: vfio 0000:03:00.0: failed to setup container

I cannot easily do bisect on this machine, but if you have problem to reproduce it, I can probably try to setup other machine and run upstream bisect there.

Anyway, I think this is a major regression.

Thanks,
Milan
