+## NFS
+
+<https://www.techrepublic.com/article/kerberos-authentication-with-nfsv4/>
+
+```bash
+mkdir /exports
+chmod 1777 /exports
+mount --bind /srv /exports/srv
+```
+
+What this does is remounts /srv to /exports/srv. Effectively, this means that
+/srv can be accessed directly, or via /exports/srv and changes in one location
+reflect in the other.
+
+To make this persistent, add the mount command above to /etc/rc.d/rc.local or
+some similar executed-at-boot script.
+
+Next, edit `/etc/sysconfig/nfs` and enable the SECURE_NFS option:
+
+```conf
+SECURE_NFS="yes"
+```
+
+Then edit `/etc/exports`. The “/exports” entry has the “fsid=0” option, which
+tells NFS that this is the “root” export.
+
+```fstab
+/exports     gss/krb5(rw,sync,fsid=0,insecure,no_subtree_check)
+
+/exports/srv gss/krb5(rw,sync,nohide,insecure,no_subtree_check)
+```
+
+Create the server principal for the NFS server and add it to the keytab file on
+the server using kadmin (usually /etc/krb5.keytab):
+
+```bash
+kadmin.local
+
+kadmin.local: addprinc -randkey nfs/nfsserver.domain.com
+kadmin.local: ktadd -e des-cbc-crc:normal -k /etc/krb5.keytab nfs/nfsserver.domain.com
+kadmin.local: quit
+```
+
+Edit `/etc/idmapd.conf` and make sure the Nobody-User and Nobody-Group options
+are correct (i.e. on Red Hat Enterprise Linux and Fedora, use the “nfsnobody”
+user and group, other distributions may just use “nobody”)
+
+```bash
+systemctl restart nfs rpcidmapd
+```
+
+open TCP port 2049 for use with NFsv4
+
+```bash
+firewall-cmd --add-service=nfs
+firewall-cmd --add-service=nfs --permanent
+firewall-cmd --reload
+```

+## Virsh Networking
+
+### Create a Virtual Network
+
+Creating a new network will require an XML configuration file. To see the
+default network's configuration, use 
+
+```bash
+virsh net-dumpxml default > virbr0.xml
+```
+
+To create a dual-stack network, use the following. (Note, I generated a unique
+local ipv6 address [here](https://www.unique-local-ipv6.com/)).
+
+```xml
+<network>
+  <name>dual-stack</name>
+  <forward mode="nat"/>
+  <domain name="dual-stack"/>
+  <ip address="192.168.100.1" netmask="255.255.255.0">
+    <dhcp>
+      <range start="192.168.100.2" end="192.168.100.254"/>
+    </dhcp>
+  </ip>
+  <ip family="ipv6" address="fd4d:58e7:17f6:1::1" prefix="64"/>
+</network>
+```
+
+I've already defined this network in `active/software_virsh/dual-stack-dhcp.xml`. Install it with
+
+```bash
+# Define and autostart the network
+virsh net-define active/software_virsh/dual-stack-dhcp.xml
+virsh net-start dual-stack-dhcp
+virsh net-autostart dual-stack-dhcp
+
+# List networks to ensure it created
+virsh net-list --all
+
+# Get the UUID of the created network
+virsh net-uuid dual-stack-dhcp
+```
+
+### Attach a New Virtual Network
+
+```bash
+export VM_NAME=my_vm
+virsh attach-interface \
+--type bridge \
+--source virbr1 \
+--model virtio \
+--config \
+--live \
+--domain ${VM_NAME}
+```
+
+### Set a Static IP
+
+To set a static IP, run `virsh net-edit default` and add the following between `<dhcp>` and `</dhcp>`
+
+```xml
+<host mac='xx:xx:0x:xx:xx:1x' name='virtual_machine' ip='1xx.1xx.1xx.xx'/>
+```
+
+Then run
+
+```bash
+# `--location /path/to/image.iso` supplies a disk installer. (Remove `--import`)
+# `--import` skips the installation process.
+# `--graphics spice --video qxl --channel spicevmc` installs graphics
+# `--console pty,target.type=virtio` adds a console connection
+# For any command, use `virt-install --arg=?` to see all available options
+virsh net-destroy default
+virsh net-start default
+virsh shutdown virtual_machine
+systemctl restart libvirtd
+virsh start virtual_machine
+```
+
+## Creating VMs
+
+If you have [an osbuild
+image](/active/software_osbuild/image_builder.md#installing) you can run the
+following to generate a qcow2 disk image. Then you can [create a VM with an
+existing qcow2
+disk](#create-vm-with-no-graphics-and-use-an-existing-qcow2-disk) and skip the
+installation process altogether.
+
+```bash
+sudo systemctl start osbuild-composer.socket
+composer-cli compose list
+composer-cli compose image --filename /var/lib/libvirt/images/fedora-42-test.qcow2 image-uuid
+```
+
+### Create VM with No Graphics and use an Existing QCOW2 Disk
+
