9.2. Booting a Guest Using PXE
This section demonstrates how to boot a guest virtual machine with PXE.
9.2.1. Using bridged networking
Procedure 9.2. Booting a guest using PXE and bridged networking
- Ensure bridging is enabled such that the PXE boot server is available on the network.
- 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>
9.2.2. Using a Private libvirt Network
Procedure 9.3. Using a private libvirt network
- Configure PXE booting on libvirt as shown in Section 9.1.1, “Setting up a PXE Boot Server on a Private libvirt Network”.
- 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
Alternatively, ensure that the guest network is configured to use your private libvirt 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>
Also ensure that the guest virtual machine is connected to the private network:
<interface type='network'> <mac address='52:54:00:66:79:14'/> <source network='default'/> <target dev='vnet0'/> <alias name='net0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface>
