libvirt has some problems to use qemu on MacOS

Software environment

• Operating system: Mac OS Ventura 13.4.1
• Architecture: arm64 (Apple M1 Max)
• kernel version: 22.5.0
• libvirt version: 9.6.0
• Hypervisor and version: qemu 8.0.3

Description of problem

It seams like there is a problem on my mac with libvirt using qemu, when i resize a image, create a new qcow2 image or run a qemu machine. It worked the last days and stopped working today, but I don't know why and how to solve it. Seems like sysconf(_SC_OPEN_MAX) has something to do with it, but I don't know what exactly it does and how it causes this problem or even how I could solve it.

Here is the log:

Steps to reproduce

1. brew install qemu libvirt
2. sudo brew service start libvirt (or to see the logs: sudo /opt/homebrew/opt/libvirt/sbin/libvirtd -f /opt/homebrew/etc/libvirt/libvirtd.conf )
3. `sudo virsh pool-define-as --name default --type dir --target /opt/homebrew/var/lib/libvirt/images/
4. sudo virsh vol-create-as --pool default --name test-volume --capacity 10GB --format qcow2 => first Error (btw. sudo virsh vol-create-as --pool default --name test-volume2 --capacity 10 --format raw
5. sudo /opt/homebrew/bin/qemu-img resize /opt/homebrew/var/lib/libvirt/images/test-image 10000000000=> works without a problem
6. sudo virsh define --file domain.xml => second Error
