encryptblockr

I am unable to create VMs on this XCP-ng host i installed from scratch.

Here is logs from trying to launch a VM on it

vm.start
{
  "id": "156afbfe-ec01-cab8-0fa4-7f14ffb5a348"
}
{
  "code": "NO_HOSTS_AVAILABLE",
  "params": [],
  "call": {

    "params": [
      "OpaqueRef:8954728c-4a96-47b5-b685-38c4707f7d1c",
      false,
      false
    ]
  },
  "message": "NO_HOSTS_AVAILABLE()",
  "name": "XapiError",
  "stack": "XapiError: NO_HOSTS_AVAILABLE()

}

anything am missing here. I have also installed all patches and rebooted the host and still issue creating VM on it.

How much RAM does the system have? my first guess is the host doesn't have enough free RAM to start the VM, the dom0 management VM will take some up, plus whatever VM you're trying to start

fixed!

issue was virtualization was not enabled in BIOS settings
logs on XOA was not good enough

xcp-ng center gave me a better error log message of HVM is Required for this Operation

thanks!

Ping @pdonias about improving logs. We'll see what XCP-ng Center is doing to "guess" the issue behind the scene

@thelearner What's the hardware your trying to work with, could you make a screenshot of the bios settings?
