Hey, I am using Xen 4.1.4 downloaded from apt-get with Debian 7.0 "Wheezy". Debian boots fine, but when I try to select the Xen kernel in grub, it just boots to a black screen. The only text that comes up before the black screen is "loading initial ramdisk" I''ve just purchased a new Asus laptop and am wondering if it has something to do with the hardware. I have been able to install Xen on another machine and in virtualbox with out any problem. I have tried placing "nomodeset" as a kernel parameter, but have had no luck with it. Any help would be great Thanks, Josh ________________________________ This message and all attachments are PRIVATE, and contain information that is PROPRIETARY to Intelligent Automation, Inc.

Can you see the Xen''s booting output, before it attempts to load
Dom0''s kernel?
Does your machine respond via network a while after booting?

To discard video mode problems, you may try "vga=normal" kernel
parameter, it''s the most fail-safe, AFAIK,
Greetings.

Hello. El 14/06/13 12:19, Joshua Tuttle escribió:> Here is my grub.cfgLooks fine to me.

Hey, Thanks for looking at it. I followed your suggestions, and removed "quiet" and replaced it with "vga=normal", but all it does now is cause a boot loop. The "Loading initial ramdisk" comes before Xen''s dmesg output which I do not see at any time.

I believe I had a similar problem with a Marvell SATA controller. I could boot from the standard kernel, but not the Xen kernel. Luckily my desktop motherboard also had an Intel SATA controller.
