Re: Installing a Linux Guest Using Only The XAPI CLI?

[Practical XenServer <practicalxenserver@xxxxxxxxx>]

For example: I've attempted to create a CentOS guest by following the instructions in Section 5 of the Citrix XenServer 7.2 Virtual Machine User's Guide...

1. I've made the contents of the CentOS installation image available via NFS: On the lab NFS server...

# mount -t iso9660 /srv/images/ISO/CentOS-7.7-x86_64-Minimal.iso /srv/pkgs/ISO/

2. I've created the VM:

# xe vm-install template=CentOS\ 7 new-name-label=CentOS7-2 sr-uuid=21044441-dfba-9293-408b-41379e194718
2a56158d-9759-03af-568a-648399d5754f

3. I've created the VIF:

# xe network-list bridge=xenbr0
uuid ( RO)                : 47a6223e-74d0-b75d-bec3-0ca6324b498c
          name-label ( RW): Pool-wide network associated with eth0
    name-description ( RW):
              bridge ( RO): xenbr0

# xe vif-create vm-uuid=2a56158d-9759-03af-568a-648399d5754f network-uuid=47a6223e-74d0-b75d-bec3-0ca6324b498c mac=random device=0
c2aa8481-f8b4-bc65-1f13-24bad54f9c5c

4. I've configured the installation repository:

# xe vm-param-set uuid=2a56158d-9759-03af-568a-648399d5754f other-config:install-repository=nfs://192.168.0.95:/srv/pkgs/ISO

5. I've started the guest:

# xe vm-start uuid=2a56158d-9759-03af-568a-648399d5754f

# xe vm-list name-label=CentOS7-2 params=dom-id,uuid,name-label,power-state
uuid ( RO)           : 2a56158d-9759-03af-568a-648399d5754f
     name-label ( RW): CentOS7-2
    power-state ( RO): running
         dom-id ( RO): 1

But the guest doesn't have an entry in Xenstore (so I'm not able to connect to the guests's console to perform the installation):

# xenstore-read /local/domain/1

xenstore-read: couldn't read path /local/domain/1

What have I done wrong?

Hello, All!

I'm looking for a good reference for installing a Linux guest in XCP-ng/XenServer using only the XAPI CLI. (I've read Section 5 of the Citrix XenServer 7.2 Virtual Machine User's Guide, "Creating Linux VM's". But it's lacking some details. So I'm looking for something more complete.)

Are there instructions available for doing that?
