Terraform error vsphere provider

[sebsot]

Hi, im currently trying to deploy VM's from terraform using the vsphere provider (terraform version v1.10.4 and vsphere provider v2.10.0) and i get an error when i try to deploy them from a template.

The main issue is when i use the customize option , where is the moment i get the error.

I get the following error:

Someone told me that the text marked in bold might be important.

i also give you the customize part

clone {

template_uuid = data.vsphere_virtual_machine.template.id

customize {

linux_options {

host_name = "server"

domain = "domain"

}

network_interface {

ipv4_address = "1.1.1.2"

ipv4_netmask = 24

}

ipv4_gateway = "1.1.1.254"

dns_server_list = ["10.1.2.3", "10.1.2.9"]

}

}

}

The ip's are examples

I tried using .OVA templates like the terraforms docs told me to, but i was unsuccesful. I would love to get some help please

cheers !

Hi @sebsot,
I have meet this problem in the same case. Did you resovled it yet?

[sebsot]

Hi @IIJ-DanhDo, yes, i remember the main problem was with the compatibility with the hypervisor and Guest OS version: https://partnerweb.vmware.com/programs/guestOS/guest-os-customization-matrix.pdf
I solved it by using cloud-init with Debian 12, because my hypervisor wouldn’t support customization. Hope it helps you :)

Hi @sebsot,
Thanks for your valuable feedback. I'll note them.
And in my case, when the step customization process, if the DRS execute migration the virtual machine that will failed. When I provision multiple VMs, some are still success.

Hi @IIJ-DanhDo, if somehow a VM is still created, then it might be another issue. In my case I wasn’t able to even create a VM
