@savage79 Please take a look at https://xcp-ng.org/forum/post/58196

A test was recently pushed to XTF's repository which may crash a host whose hardware is vulnerable to XSA-304 (hardware vulnerability related to EPT superpages).

There are two modes in Xen regarding EPT superpages, fast vs secure, and XCP-ng defaults to fast due to the big performance hit secure would have by default on affected hardware. The vulnerability may allow an HVM guest to crash the host, and this is what the test demonstrates.

I've updated the small Xen testing guide above with instructions to switch to secure mode before running the tests, if you want to avoid the crash in case your host is vulnerable.

Can you try on XOA in trial? (if you trial expired, PM me your registered email so I can extend it)

Yes, that's the export button. Are you on XOA Free for the first screenshot?

Indeed, we can't support versions that have patched since, for a lot of reasons
