default 값 수정 및 변수 추가

  • esxi_vm_functions.py
    • VIRTDEV, NETDRIVER : 파리미터로 받아 변수 지정으로 위하여 default 값을 지정
    • VIRTDEV : vSCSI Controller
    • NETDRIVER : Network Adapter(Driver)
    • 그 밖에 자주 사용하는 VM spec(cpu,memory,disk) 변경, DISKFORMAT 변경
def setup_config():

    #
    #   System wide defaults
    #
    ConfigData = dict(

        #   Your logfile

parser 아규먼트 추가

  • esxi-vm-create
    • DISKFORMAT, VIRTDEV, NETDRIVER 변수를 입력 값으로 받음.

vmx profile 값 수정

  • esxi-vm-create
    • nvram 추가 : bios 설정 값을 기억
    • cdrom을 ide -> sata 으로 변경

    • usb 추가

vmdk 생성 부분 변경

  • esxi-vm-create
    • paramiko -> subprocess 로 변경하고 sshpass를 사용
import subprocess

if not isDryRun and not CheckHasErrors:
    try:

...

        # Create vmdk
        if isVerbose:
            print "Create " + NAME + ".vmdk file"
        #(stdin, stdout, stderr) = ssh.exec_command("vmkfstools -c " + str(HDISK) + "G -d " + DISKFORMAT + " " + MyVM + ".vmdk")
        #type(stdin)
        config = "vmkfstools -c {a}G -d {b} {c}.vmdk".format(a=HDISK,b=DISKFORMAT,c=MyVM)
        if PASSWORD:
            cmd = 'sshpass -p\'{pw}\' ssh -o ConnectTimeout=5 -o StrictHostKeyChecking=no {ids}@{ip} \"{a}\"'.format(pw=PASSWORD,ids=USER,ip=HOST,a=config)
        else:
            cmd = 'sshpass ssh -o ConnectTimeout=5 -o StrictHostKeyChecking=no {ids}@{ip} \"{a}\"'.format(pw=PASSWORD,ids=USER,ip=HOST,a=config)
        print(cmd)
        result = subprocess.check_output(cmd, shell=True, universal_newlines=True)
...

 

 

vmx 파일 생성 부분 변경

  • esxi-vm-create
    • .vmx 파일의 VMX list가 paramiko를 통한 ssh로 put 할 시 간헐적인 입력값 누락으로 오류 발생
    •  echo를 통해 VMs list 값을 하나씩 밀어넣는 방식에서 local에서 vmx파일을 완성해서 scp로 복사하는 방법으로 변경
import os

...

if not isDryRun and not CheckHasErrors:
    try:

        # Create NAME.vmx
        if isVerbose:
            print "Create " + NAME + ".vmx file"
        (stdin, stdout, stderr) = ssh.exec_command("mkdir " + FullPath )
        type(stdin)
        fp = open('/tmp/'+NAME+'.vmx', 'a')
        for line in VMX:
            fp.write(line)
            fp.write('\n')
        fp.close()
        from scp import SCPClient
        scp = SCPClient(ssh.get_transport())
        scp.put('/tmp/'+NAME+'.vmx',MyVM+'.vmx')

        # Create vmdk
...

        # Register VM
...

        # Power on VM
...

        # Get Generated MAC
...

        # Delete local vmx file
        if os.path.exists('/tmp/'+NAME+'.vmx'):
            os.remove('/tmp/'+NAME+'.vmx')
    except:
