Hello! I need to create a VM and passthrought some host USB port to it. Sadly libvirt doesn’t support QEMU built-in feature to use -hostport argument (which was added 10 years ago…). I tried to add custom arguments to domain (qemu:commandline) but this didn’t work. When I just run qemu-system-x86_64 -device host-usb,hostbus=X,hostport=Y -usb everything works well. It seems like libvirt restricts some QEMU actions. How can I fix this? OS: Debian 12
Not the person you were replying to, and don’t understand exactly what you mean with port and device id. But if it changes every time, -ish, you plug it in, do you mean like /dev/sdX device names? If so, then maybe look at /dev/disk/by-TYPE/ and use those instead? You have stuff there which is the same each time you plug in.
