| | |
| | /etc/libvirt/ Holds QEMU/Libvirt configurations files are. |
| | /etc/libvirt/hooks/ Holds your own scripts that would starts when a specific VM does. |
| | /etc/libvirt/nwfilter/ Looks like Libvirt has its own networking/firewall rules. |
| | /etc/libvirt/qemu/ Holds VMs' XMLs are stored. |
| | /etc/libvirt/qemu/networks/ Holds QEMU/Libvirt virtual networks' XMLs are. |
| | /etc/libvirt/qemu/networks/autostart/ A QEMU/Libvirt virtual network XML symlinked there will make said virtual network starts when QEMU/Libvirt does. |
| | /etc/libvirt/secrets/ ??? |
| | /etc/libvirt/storage/ Holds QEMU/Libvirt datastores/pool configurations files are. |
| | /etc/libvirt/storage/autostart/ A QEMU/Libvirt datastore/pool configuration file symlinked there will make said datastore/pool starts when QEMU/Libvirt does. |
| | |
| | /var/lib/libvirt/boot/ ??? |
| | /var/lib/libvirt/dnsmasq/ Holds further QEMU/Libvirt virtual networks' configuration files. |
| | /var/lib/libvirt/images/ Default QEMU/Libvirt virtual disks' datastore/pool. |
| | /var/lib/libvirt/qemu/ ??? |
| | /var/lib/libvirt/qemu/channel/ ??? |
| | /var/lib/libvirt/qemu/target/ ??? |
| | /var/lib/libvirt/qemu/checkpoint/ ??? |
| | /var/lib/libvirt/qemu/dump/ ??? |
| | /var/lib/libvirt/qemu/nvram/ Holds VMs' UEFI settings. Same goes for TPM and Secure Boot databases? |
| | /var/lib/libvirt/qemu/ram/ ??? |
| | /var/lib/libvirt/qemu/ram/libvirt/ ??? |
| | /var/lib/libvirt/qemu/libvirt/qemu/ ??? |
| | /var/lib/libvirt/qemu/save/ Looks like it holds VMs' saved states. |
| | /var/lib/libvirt/qemu/snapshot/ Looks like it's where VMs' snapshot are saved. |
| | /var/lib/libvirt/sanlock/ ??? |
