RE: [Xen-devel] Re: [Xen-users] Xen 4.0.0-rc6 - Linux paravirt_

It might not be a recommended way to learn (or play around with) how to boot Xen with the Grub2 bootloader, but I found that it was easier to edit the /boot/grub/grub.cfg file directly and ensure that update-grub is not executed so that grub.cfg is not over-written. I kept playing around with the a custom menuentry until I found one that worked.

At that point you can place that working entry in a executable file located inside the /etc/grub folder. Then run update-grub, and confirm your working entry is now in the grub.cfg

Just my two cents...

No, even the bare Linux (the same vmlinuz and ramdisk images used by Xen as dom0) doesn't boot by Grub2 (without Xen)... With Grub1 all works just fine... Maybe the problem is with me, I'm not familiar with Grub2...  hehehe... But I tryed it (Grub2) a lot without success...

What's wrong with native Grub2 ( it doesn't load Xen Instance ?)

 For the first time, I have the Xen 4.0.0-rc6 with Linux as my dom0 using the paravirt_ops.

 The Intel modesetting is working too!

 My xm info shows:

 To install the "tools", I need to run:

make install-tools PYTHON_PREFIX_ARG=

 And I'm using the Grub1.

 Now it is time to make a few domUs!
