don't use /root

[Sun, 05 May 2024 23:32:31 virt-install 61955] WARNING (cli:309) /root/vms/virsh/images/vm1.img may not be accessible by the hypervisor. You will need to grant the 'libvirt-qemu' user search permissions for the following directories: ['/root']

very bad idea - use /root as default, need use /var/lib/libvirt/*
