iSCSI boot and XEN hypervisor

[CGen]

Hello!

I recently installed a new Ubuntu 13.04 server directly on the iSCSI-drive. In the installer there is a great opportunity to do so.

Then I set everything to download using iPXE. Everything is working fine.

I then installed the xen hypervisor on the server.
Grub menu is displayed. I choose the item with Xen. grub displays a message that the kernel is loaded. Then a black screen and all.
I can not understand why.

Can anybody help?

Kernel and initrd.img is same in the case with Xen and without it.

I'm a bit confused. Did you install the Xen hypervisor on the machine that is iSCSI-booted? If you're using iPXE and sanboot to boot this machine, then I'm going to assume a different kernel+initrd is in use. It might also be a bug in the Ubuntu initramfs when used together with iSCSI boot and Xen. I'd suggest you use just text console and increase the debug level to ensure you actually see the kernel log as you boot. Most likely you're getting some kind of kernel panic because of the Xen/iSCSI boot interaction.

If you're able to get into grub and the kernel is able to execute then I think this might be a Linux/Ubuntu problem, not an iPXE problem. I'd suggest you try and grab some debug information and post it here.

Thank you!

I also think the problem is in the raw Ubuntu. I'll dig :-).

Strange, but the kernel+initrd is only one.

Hi!

I tried the Intel ® iSCSI Remote Boot.
Ubuntu + XEN is loaded as expected.
