The initialization of packer core in JSON also validates that `null` variables were set, except in the case of `packer validate --syntax-only` , but after the refactor to allow to have all commands work with HCL2 and JSON this subtlety was lost.
This refactors the initialisation of the core in order to allow to have `packer validate --syntax-only` not error in case a variable is not set. Since these calls are refactored this works for HCL2 too.
fix#9478
* add kex algorithm option to ssh config
* regenerate code
* This commit fixes old vmware acceptance tests that have not been run in some time. It does this in two parts:
1) It modifies the minimal vmware build configuration to use a custom kex algorithm, which enables the ssh connection to succeed.
2) It modifies logic in reading and defaulting hardware config values, which was crashing.
3) It adds a new acceptance test with a preseed file to test loading from an http directory.
This avoids the need to expose WinRM ports on the internet and allows
using instances with only an internal private IP address.
When using a WinRM tunnel there is a race condition between the tunnel
connection attempt timing out and packer assuming the connection was
successful. To allow for this, when using WinRM the default success
timeout is increased to 40 seconds.
