Using a virtual PTP hardware clock with the ptp_kvm driver and chrony is an easy solution for keeping time on guest machines synchronized to their host. Ideally the host is already keeping accurate time by tracking a set of NTP servers, but it is still probably a good idea to still add some network NTP peers on guests as well. (more…)

If you find yourself with an old Terraform state file (say from v0.11) and you need to run terraform plan to check things out, you’ll need to make some adjustments:

• Add a terraform block with required_providers to provide the source for the provider.
• Remove the version statement from the provider block. (You will want to move it to the provider in the required_providers block.)
• Adjust any other syntax changes that result in errors (terraform plan):
  • list() → tolist([])
  • type = "string" → type = string
  • Possibly many others…
• Replace the provider in the existing ancient state file.
• Refresh the providers (terraform init).
• Plan away! (more…)
