Nothing really new to say.  The documentation for 3.1 VS Migration says that the only version of windows that cannot be live migrated in OnApp is 2003.  Now during testing I find our 2008R2 and 2012 test VSs can't be live migrated.  Seeing as we come from an ESX and XenServer background this is rather surprising.

Is there a roadmap for including hot migration for existing Windows templates.   Will the 2012R2 templates be supported for Hot Migration when they are release?

  Hello David and Niclas,

  Sorry for the late reply. I have discussed this topic with our QA engineers and I can assure you that the following x86 and x64 templates should support hot-migrate on the CentOS 6 / 7 (KVM and XEN) Compute Resources:

  Windows Server 2008

  Windows Server 2012

  Windows Server 2016

  Windows 7

  Windows 8

  Windows 8.1

  Windows 10

  In case you find that a template does not support hot-migrate, please update it to the latest version and check whether you have the latest supported OnApp release (currently 6.0 LTS) installed on Control Panel and Compute Resources.

  If the template still doesn't allow hot-migrate please create a Support Ticket and check for Release Notes. Our support engineers will pass the ticket to development and QA side for inspection and fixing.

  Hi David,

  In most cases hot migrate for Windows templates should be fine, although is not enabled by default currently pending updated QA template testing results. You can enable this for testing with the following for example:

  update templates set allowed_hot_migrate=1 where file_name=
  'win12_x64_std-sqlweb-ver3.2-kvm_virtio.tar.gz';

  Note, for KVM with CentOS 6 HVs, hot migrate will only work with templates with kvm_virtio enabled, you will see this mentioned in the filename.

  Is there any progress on this - is QA done yet?
