Measured on a VM with two disks, a CD-ROM and a NIC: 70 libvirt calls per page, now 43. Within the page's cached_reads block the VM's state, the host's info and domain capabilities, and each disk path's volume are read once; the running and the persistent disk lists share a path's volume. The ISO list takes the active pools in one call instead of looking each up by name; it still refreshes them, so an image copied in by hand shows up. The opt-in DRBD status waits at most 10 s for the compute's ssh, then leaves the status unknown instead of holding the page.
