<p>Build worker image not found: Windows Server 2019</p>
<p>so I guessed, I need to send an email to the appveyor support for the activation of this image for my account. Maybe using the Windows Server 2019 has nested virtualization enabled (just guessing from <a href="https://help.appveyor.com/discussions/problems/22269-packer-build-fails-on-vboxmanage-error-vboxmanage-error-vt-x-is-not-available-verr_vmx_no_vmx">https://help.appveyor.com/discussions/problems/22269-packer-build-f...</a>)?!</p>
<p>Oh, and since my account <a href="https://ci.appveyor.com/project/jonashackt/">https://ci.appveyor.com/project/jonashackt/</a> is somehow blocked right now (see <a href="https://help.appveyor.com/discussions/problems/26379-no-builds-are-triggered-anymore-no-new-project-can-be-added-there-was-an-error-while-trying-to-complete-the-current-operation-please-contact-appveyor-support">https://help.appveyor.com/discussions/problems/26379-no-builds-are-...</a>), it would be great to have my account unblocked bevor. The account <a href="https://ci.appveyor.com/project/quakefrog">https://ci.appveyor.com/project/quakefrog</a> was just created, since the other one didn't work anymore.</p></div>jonashackttag:help.appveyor.com,2012-11-13:Comment/481119382020-02-24T17:58:29Z2020-02-24T17:58:29ZNested Virtualization needed for OpenSource projects (VT-x is not available (VERR_VMX_NO_VMX))<div><p>Hi Jonas,</p>
<p>Thank you for using AppVeyor!</p>
<p>Right now <code>Visual Studio 2019</code> image is the one based on Windows Server 2019 OS with nested virtualization enabled. It has Hyper-V components installed as well. This image is available to all AppVeyor users without request.</p>
<p>We've unlocked your account - it should be fine now. So, please give that image a try and let us know if there are any issues.</p>
<p>And, of course, a blog post will be super helpful! :) Thank you for your support!</p></div>Feodor Fitsner
