Yes, we use cgroups extensively already.
Ok, I will try to see about this
Can you also tell me if the selinux/seccomp will prevent qemu from opening more than one /dev/vfio/vfio ? I suppose the answer is no?
QEMU manages the container:group association with legacy vfio, so it can't be restricted from creating multiple containers. Thanks,
.. and it absolutely will create multiple containers (i.e. open /dev/vfio/vfio multiple times) if there are multiple guest-side vIOMMU domains. It can, however, open each /dev/vfio/NN group file only once each, since they are exclusive access. -- David Gibson | I'll have my music baroque, and my code david AT gibson.dropbear.id.au | minimalist, thank you.
