Create local ISO repository xcp-ng doc

1. ssh to ng01 server create Local_ISO directory and pull down small debian LT-video

   [08:20 nsg01 ~]# cd /
   [08:55 nsg01 /]# mkdir Local_ISO
   [08:55 nsg01 /]# cd Local_ISO/
   [08:55 nsg01 Local_ISO]# pwd

2. Go to XOA - New - Storage and create Local ISO storage LT-video
   • Host: nsg01
   • Name: Local ISO
   • Description: Small ISO storage for server bootstrap
   • Select Storge Type: ISO SR - Local
   • Path: /Local_ISO
   • Click Create
3. Verify iso XOA - Home - Storages - Local ISO - Disk to verify debian iso

Add Remote Storage

1. Go to XOA - New - Storage and create FreeNAS NFS storage LT-video
   • Host: nsg01
   • Name: FreeNAS NFS
   • Description: FreeNAS NFS storage on local network
   • Select Storge Type: VDI SR - NFS
   • Server: 192.168.2.83
   • Path: (should query the server) /mnt/nspool/
   • Click Create

Add Local Disks

• Install a hard drive on a XenServer.
• Run the following command from the command line interface to display the installed disks:

  fdisk -l
  lsblk
  

• Inspect the disks partitions

  cfdisk /dev/sdc
  

• List the xen server ID

  xe host-list
  

• Run the following command from the command line interface:

  xe sr-create host-uuid<hostid> name-label=<nameLabel> shared=false device-config:device=<devicePath> type=lvm content-type=user
  

  • hostID: is shown by xe host-list (just tab if your on the server)
  • nameLabel: is the display name used in XCP-ng
  • devicePath: shown in fdisk -l or lsblk /dev/sdc
• Example I ran on hsg04

  xe sr-create host-uuid=7749xxxx-xxxx-xxxx-xxxx-xxxxxxxxxxb0 name-label-"hsg04d2" shared=false device-config=/dev/sdb type=lvm content-type=user
  

  1. Pass-through Storage
• Run the following command from the command line interface to display the installed disks:

  lsblk
  

• Inspect the disks partitions delete partitions you want to re-use

  cfdisk /dev/sdc
  

• List the xen server ID

  xe host-list
  

• Make directory with symlinks to devices you want to pass-through

  cd /srv/
  mkdir pass_drives
  cd pass_drives
  ln -s /dev/sdc
  

• Run the following command from the command line interface:

  xe sr-create name-label=Pass_Drives type=udev content-type=disk device-config:location=/srv/pass_drives 
  

  • hostID: is shown by xe host-list
  • nameLabel: is the display name used in XCP-ng
  • devicePath: shown in fdisk -l or lsblk - /dev/sdc
• fire up vm and connect
