ZFS storage backend

I'm running libvirt to manage virtual machines utilizing ZFS zvol's for storage. For organization and management purposes, these zvol's are nested: virt/qemu/debian12-template 15.8G 1.57T 24K none virt/qemu/debian12-template/bootefi 1.02G 1.57T 141M - virt/qemu/debian12-template/home 522M 1.57T 2.57M - virt/qemu/debian12-template/opt 522M 1.57T 3.00M - virt/qemu/debian12-template/root 8.13G 1.58T 970M - virt/qemu/debian12-template/swap 522M 1.57T 366M - virt/qemu/debian12-template/tmp 522M 1.57T 2.39M - virt/qemu/debian12-template/var 3.05G 1.57T 161M - virt/qemu/debian12-template/varlog 1.02G 1.57T 101M - virt/qemu/debian12-template/vartmp 522M 1.57T 3.75M - The libvirt ZFS integration seems to assume that all zvol's will exist at the top level of the pool, it won't let you create or manage a hierarchical structure. That is what it is, but it also then misrepresents the actual structure and shows things as being in the root when they are not: virsh # vol-list virt Name Path ------------------------------------- backup /dev/zvol/virt/backup boot-nb /dev/zvol/virt/boot-nb bootefi /dev/zvol/virt/bootefi dest /dev/zvol/virt/dest disk1 /dev/zvol/virt/disk1 home /dev/zvol/virt/home opt /dev/zvol/virt/opt root /dev/zvol/virt/root swap /dev/zvol/virt/swap tmp /dev/zvol/virt/tmp usr /dev/zvol/virt/usr usrlocal /dev/zvol/virt/usrlocal usrobj /dev/zvol/virt/usrobj usrports /dev/zvol/virt/usrports usrsrc /dev/zvol/virt/usrsrc var /dev/zvol/virt/var varlog /dev/zvol/virt/varlog vartmp /dev/zvol/virt/vartmp Ideally libvirt would support nested ZFS organizational structure, as that is a very common layout. But even if not, it probably shouldn't misrepresent a structure it doesn't understand? Thanks for any thoughts…
