something (qemu?) is leaking

Hi guys. I do a simple thing which should be easy to reproduce. -> $ virt-install -n rum1 --virt-type kvm --os-variant centos8 --memory $((4*1024)) --disk=/VMs3/rum1.qcow2,device=disk,bus=virtio --network network=10_3_1,model=virtio --graphics=listen=0.0.0.0 --cpu EPYC-Rome --vcpus 3 --cdrom /VMs3/CentOS-Stream-9-latest-x86_64-dvd1.iso During manual setup in the VM I set 'hostname' to something and when installation begins and disk config stage takes place I can see - and later when VM(c9s) is ready can confirm - that VG name is taken from another VM defined/running on the host. Host is c9s with: qemu-kvm-7.0.0-1.el9.x86_64 libvirt-daemon-8.2.0-1.el9.x86_64 5.14.0-86.el9.x86_64 Does anybody see this/similar? many thanks, L.
