Pxeboot: 클라이언트가 DHCP 서버에서 IP 주소를 얻지 못했습니다.

저는 Pxeboot에서 작업 중입니다. KVM으로 Ubuntu 시스템이 있고 시스템에 가상 머신 관리자를 설치했습니다.

또한 가상 머신에 Ubuntu를 설치했습니다.

가상 머신을 시작하기 전에 가상 네트워크 인터페이스를 연결했습니다.

Source device: Host device eth0:macvtap
Device model : Hypervisor default
Mac Address  : 00:22:11:01:22:55
Source mode  : private

가상 머신에 DHCP 서버를 설치했습니다.

# apt-get install isc-dhcp-server

그리고 파일에서 구성하십시오 dhcpd.conf.

allow booting;
allow bootp;

filename "pxelinux.0"

subnet 10.5.5.0 netmask 255.255.255.0 {
  range 10.5.5.5 10.5.5.100;
  option domain-name-servers ns1.testworld.local.net;
  option domain-name "testworld.local.net";
  option routers 10.5.5.1;
  option broadcast-address 10.5.5.254;
  default-lease-time 600;
  max-lease-time 7200;
 }

host pxebootserver {
  hardware ethernet 00:22:11:01:22:55      
  fixed-address 10.5.5.1
 }

isc-dhcp-server를 다시 시작하면 시스템 로그에 다음 오류가 표시됩니다.

클라이언트조차도 DHCP 서버를 검색할 수 없습니다.

클라이언트 VM에서 어떤 가상 네트워크 어댑터를 활성화해야 합니까?
