[sles-beta] Support status for Citrix XenServer?

Wed Jun 25 22:29:23 MDT 2014

I would have thought that a grub issue would stop it cold before anything was loaded from disk...maybe just presenting a blinking cursor.  With this, it looks like it is getting past the bootloader.
If there are any logs/info I can provide from the XenServer host or if I can figure out how to get them off of the guest os, I will be glad to.
Should I open an SR for this?

To me it seems like grub2 is the most likely culprit. We will need to work with Citrix to see what support they can add to accommodate it.

I have not been able to get a working installation of any of the betas on there using a SLES template. If I use the "other install media" template, I can get a functioning HVM install, but if I use one of the proper templates for paravirtualization, I cannot get a working install.  Obviously, the HVM is an inefficient virtualization method on Xen, and is not recommended.
