xenserver-iso: Ошибка загрузки: открыто: нет такого файла или каталога

Я пытаюсь создать образ "vdi_vhd" с помощью упаковщика на xenserver, но у меня возникла ошибка, приведенная ниже. Не могли бы вы помочь мне с этим, заранее спасибо.

   [root@localhost bin]# packer build /usr/local/test-scripts/main.json
 xenserver-iso output will be in this color.

 ==> xenserver-iso: XAPI client session established
 ==> xenserver-iso: Downloading or copying ISO
     xenserver-iso: Downloading or copying: http://www.mirrorservice.org/sites/mirror.centos.org/7.6.1810/isos/x86_64/CentOS-7-x86_64-Minimal-1810.iso
     xenserver-iso: Error downloading: open : no such file or directory
 ==> xenserver-iso: ISO download failed. Build 'xenserver-iso' errored: ISO download failed.

 ==> Some builds didn't complete successfully and had errors:
 --> xenserver-iso: ISO download failed.

 ==> Builds finished but no artifacts were created.

Вот шаги, которые я использовал для установки упаковщика

mkdir -p /usr/local/packer/
cd /usr/local/packer/
wget https://releases.hashicorp.com/packer/1.4.1/packer_1.4.1_linux_amd64.zip
unzip packer_1.4.1_linux_amd64.zip
vim ~/.bashrc
##added the below
export PATH=/usr/local/packer/:$PATH
##save and exit
sudo ln -s /usr/local/packer/packer /usr/bin/packer
source ~/.bashrc

Это шаги, которые я использовал для установки плагина xenserver-iso

RELEASE="go1.12.6.linux-amd64.tar.gz";
cd /tmp && curl -L -O "https://dl.google.com/go/${RELEASE}";
tar -zxvf "${RELEASE}";
mv -v go $HOME/go-1.12.6;
rm -f "/tmp/${RELEASE}";
vim ~/.bashrc
##added the below
export GOROOT=$HOME/go-1.12.6;
export GOPATH=$HOME/go-workspace;
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin;
##save and exit

source ~/.bashrc
mkdir -p $GOPATH/src/github.com/hashicorp/packer;
cd $GOPATH/src/github.com/hashicorp/packer;
go get github.com/mitchellh/gox;
go get github.com/mitchellh/go-vnc;
cd $GOPATH;
PROV="src/github.com/xenserver";
mkdir -p $PROV && cd $PROV;
git clone https://github.com/xenserver/packer-builder-xenserver.git;
cd packer-builder-xenserver;
./build.sh;

проверить плагин

[root@localhost bin]# ll
total 34732
-rwxr-xr-x. 1 root root 17813736 Jul  2 12:04 packer-builder-xenserver-iso
-rwxr-xr-x. 1 root root 17747856 Jul  2 12:04 packer-builder-xenserver-xva
[root@localhost bin]# pwd
/root/go-workspace/src/github.com/xenserver/packer-builder-xenserver/bin
[root@localhost bin]#

ПРИМЕЧАНИЕ. Я установил плагин packer и xenserver на свой локальный сервер Virtual-box.

Я ожидаю, что результат будет примерно таким, как показано ниже:
