    As a test, I'm thinking I should install and test on kernel 4.4.0-28, before upgrading to 4.4.0-31... Reason? I was thinking about you today = I tried installing Xen directly onto that new server, while it was at 4.4.0-31 ... and it crashed so bad it would not boot. I ended up reinstalling a fresh install onto it!!!
    Btw, have you yet had time to try it on the Tyan board? Though Xen crashing that bad on 4.4.0-31 doesn't sound particularly good..

    Not yet. My non-Vt-x Xen Experiments have been podtponed for about another week or so.. sorry about not keeping you posted on that... My board like yours is still plugging a hole in my fabric until then. I should be back home to take care of that soon.

    Re: Xen crashes entire server when creating a virtual machine

    And just to let you know, I had yesterday an uncorrectable ECC error. When I turned ECC off and started memtest, I got a bunch of errors.. then I looked at the board and I saw some swollen capacitors..

    I don't get why it has been working fine without Xen until this point, all I have got has been occasionally some corrected ECC errors, but with Xen it imploded totally and almost instantly. Anyways, I'll change the caps, and see if that fixes the memory errors. If it doesn't, I'll have to move to a new board.

    After changing the caps and switching memory modules the ECC errors vanished, but Xen still crashes. So, it apparently wasn't about that.

    Sorry to poke you again, but what's the status? I understand that it's probably a legacy feature, and I can use Virtualbox if Xen doesn't work, even if I'd prefer to use Xen.

    Sent you a PM early this AM. Got back from holiday late last night. In the process of pulling my Tyan offline right now and another server back online in it's place.

    Once that is done, will get details from you to mirror what you have as a configuration.
