Solution for KVM:

  1. Create a virtual vetwork: Virtual Machine Manager -> Edit -> Host Details -> New (+)

    Tick off the Enable DHCP item.

  2. Add the following machines in the virtual network:
    • guest with PXE;
    • guest that needs to boot from PXE;
    • guest with DHCP.
  3. Configure the guest virtual machines:
    1. Guest machine with DHCP Server - Start the DHCP server;
    2. Guest machine with Acronis PXE server - Update gPXE to gPXE 1.0.1.

      gPXE must be specific for the network card of the guest virtual machine which will be used to boot from Acronis PXE Server.

    3. Guest machine that needs to boot from Acronis PXE Server:
      • Verify that you have a working DHCP server on Windows guest machine within the virtual network;
      • Set network boot for the machine: Edit -> Virtual Machine Details -> Boot -> Network -> Boot
      • Start the virtual machine;
      • At the very beginning of the boot process press Ctrl-B and enter the gPXE command-line utility;
      • Execute the dhcp net0 command and press Enter. The reply from the machine should be OK;
      • Enter the configuration utility by specifying the config command;
        • For the next-server parameter specify an IP address of the guest machine with DHCP;
        • For the filename parameter specify bootwiz.bin.
        • Exit the configuration utility;
        • Execute the command autoboot
