Today I upgraded from 22.04 to 24.04
I have a VM with 16GB of hugepages allocated to it.
This no longer works.
I can not defeat the virtual machine start up error (from virtual manager):
Error starting domain: internal error: QEMU unexpectedly closed the monitor (vm='ubuntu24.04'): 2024-07-16T04:54:51.443751Z qemu-system-x86_64: failed to resize memfd to 17179869184: Permission denied

sudo mount -t hugetlbfs -o mode=1770,gid=kvm none /dev/hugepages

I have edited /etc/libvirt/qemu.conf to uncomment the mount point of the hugepages, even though this was not necessary with 22.04
log entries don't add anything (for me):
