Re: [Xen-users] GRUB2 randomly works on some hosts but not others?

Alright, I downloaded that tarball, had to apply the patch from http://savannah.gnu.org/bugs/?41118 to get it to build, also applied all your patches from http://wiki.prgmr.com/mediawiki/index.php/Grub2

Same issue exists.

I rebuilt my image with set debug=all in my grub-bootstrap.cfg and grub.cfg. On the hosts were grub2 works i see a bunch of debug output, on the hosts were it doesnt work, nothing shows. Makes me think either grub2 is locking up right at the hit, or Xen isnt firing off grub2

I'm in your IRC channel if you'd like to talk in real time..

Grub2 doesnt have an offical release as far as I can tell, everything i've found says to grab it from git. Even the xen blog about it says that.
 Distros running grub2 these days are also running a beta.

You mean this https://blog.xenproject.org/2015/01/07/using-grub-2-as-a-bootloader-for-xen-pv-guests/ where they give you a link to a tarball to download?

I'm starting to think this may be memory related. I've tested this on a couple hosts with less than 32GB of RAM in them and grub2 seams to work on
 them.  Anything with 32 or more GB seams to fail... least so far.

It runs fine for us on physical servers with more than 32GiB ram and xen 4.4.1 from Xen4CentOS, though we aren't using the exact same xen release as
you. We're using xeons.
