9.2. Booting a Guest Using PXE

Procedure 9.2. Booting a guest using PXE and bridged networking

1. Ensure bridging is enabled such that the PXE boot server is available on the network.
2. Boot a guest virtual machine with PXE booting enabled. You can use the virt-install command to create a new virtual machine with PXE booting enabled, as shown in the following example command:

   virt-install --pxe --network bridge=breth0 --prompt

   Alternatively, ensure that the guest network is configured to use your bridged network, and that the XML guest configuration file has a <boot dev='network'/> element inside the <os> element, as shown in the following example:

   <os>
      <type arch='x86_64' machine='pc-i440fx-rhel7.0.0'>hvm</type>
      <boot dev='network'/>
      <boot dev='hd'/>
   </os>
   <interface type='bridge'>
      <mac address='52:54:00:5a:ad:cb'/>
      <source bridge='breth0'/>
      <target dev='vnet0'/>
      <alias name='net0'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
   </interface>

Procedure 9.3. Using a private libvirt network

1. Configure PXE booting on libvirt as shown in Section 9.1.1, “Setting up a PXE Boot Server on a Private libvirt Network”.
2. Boot a guest virtual machine using libvirt with PXE booting enabled. You can use the virt-install command to create/install a new virtual machine using PXE:

   virt-install --pxe --network network=default --prompt
