2011-12-04 04:42:26 -0500 commented answer Xen crashes on boot

No, I said I was booting a 64-bit kernel. What I'm trying to emphasize is a possible error in packaging, where the x86_64 xen-hypervisor actually has a 32-bit Xen in the package.

However, I have 8 GB of RAM, so I need a 64-bit Xen or a PAE Xen. My kernel is a x86_64 kernel.

gzip -dc /boot/xen-4.1.2.gz | file - yields: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), statically linked, stripped, so this is a 32-bit Xen hypervisor. I installed the x86_64 arch for xen-hypervisor, though, as yum info xen-hypervisor gives:Name : xen-hypervisor Arch :

Apologies for the late reply. Nothing's logged in /var/log/boot.log nor /var/log/messages, because Xen crashes before starting the dom0 kernel and its initrd. This is what I see for /boot/xen-4.1.2.gz:

Which alt key doesn't work? The left one or the right one?

In alsamixer, have you tried pushing all the volumes to their maxima?

Possibly, but you'd have to install the grub-efi package appropriate to your architecture afterwards (x86_64 or x686).

I'm using vanilla kernels from yum, which have dom0 support. The problem is there is no error message. I just get an immediate reboot after loading the initrd.

2011-11-30 11:52:14 -0500 asked a question Xen crashes on boot

I've not been able to get Xen 4.1.2 to boot on Fedora 16. 64-bit kernel 3.1.2 boots on bare metal from Grub2 on a GPT-labeled disk, but Xen 4.1.2 crashes immediately after loading the initrd and reboots.

The reboot happens too quickly to see any screen error messages, but I wonder if I'm hitting this problem:

From what I can see, grub2 is a 32-bit package even on 64-bit, and the Xen hypervisor is also a 32-bit package even on 64-bit. It appears that grub2 is loading the dom0 kernel in an address the hypervisor can't reach, since I have 8GB RAM installed.
