[Xen-users] Re: [Xen-devel] Re: [Xen-tools] Unable to start xend
I have followed the instructions in
http://wiki.xensource.com/xenwiki/XenParavirtOps /
Using Xen/paravirt_ops
Building with domU support
exactly ..
1. Get a current kernel. The latest kernel.org kernel is generally a good
choice.
Done
2. Configure as normal; you can start with your current .config file
Done
3. If building 32 bit kernel make sure you have CONFIG_X86_PAE enabled
(which is set by selecting CONFIG_HIGHMEM64G)
CONFIG_HIGHMEM64G=y,CONFIG_X86_PAE=y
Done
* non-PAE mode doesn''t work in 2.6.25, and has been dropped
altogether from 2.6.26 and newer kernel versions.
4. Enable these core options:
1. CONFIG_PARAVIRT_GUEST
Done - CONFIG_PARAVIRT_GUEST=y
2. CONFIG_XEN
Done - CONFIG_XEN=y
5. And Xen pv device support
1. CONFIG_HVC_DRIVER and CONFIG_HVC_XEN
Done - CONFIG_HVC_DRIVER=y
Done - CONFIG_HVC_XEN=y
2. CONFIG_XEN_BLKDEV_FRONTEND
Done - CONFIG_XEN_BLKDEV_FRONTEND=y
3. CONFIG_XEN_NETDEV_FRONTEND
Done - CONFIG_XEN_NETDEV_FRONTEND=y
6. And build as usual
make oldconfig, make -j2 bzImage modules , make -j2 modules_install ,
make install

One more notice. Running "make menuconfig" to enable Xen Dom0 support is not described in details in the post and might be hard for the first time exercise. I just attached working ".config" for 2.6.32.10 on Ubuntu 9.10 Server to this message.

Please confirm if I am right :
#!/bin/sh
cat << EOF
menuentry "Xen 3.5 / Ubuntu, 2.6.31.6-xen1" {
insmod ext2
set root=(hd0,1)
multiboot /boot/xen-3.5.gz <- This is the Xen VMM proper ???
module /boot/vmlinuz-2.6.31.6-xen1 dummy=dummy dom0_mem=1024M
root=/dev/sda1 ro <- This is linux kernel with pvops right ???
module /boot/initrd.img-2.6.31.6-xen1
}
EOF
so in my case , I have compiled Linux kernel containing pvops ; Now , I also
need Xen VMM ?? right ??
Please confirm

But from your /boot/grub/menu.lst it looks that you do have the xen-3.5.gz compiled? For details on how to do that look at the URL that Boris sent - it is pretty comprehensive. Also take a look at this (which Boris wrote as well): http://bderzhavets.wordpress.com/2009/08/31/loading-xen-via-grub2-on-top-ubuntu-karmic-server-alpha-4/ That explains how to setup the GRUB2 entry correctly.

I am confused. Just try to reproduce :- http://lxer.com/module/newswire/view/133477/index.html with .config i''ve sent to you yesterday. I believe Konrad wrote you the same. You mix several sources. I wouldn''t do that.

But from your /boot/grub/menu.lst it looks that you do have the xen-3.5.gz compiled? No , this is just the copy-paste from http://virtually-a-machine.blogspot.com/2009/12/experimental-xen-and-ubuntu-part-2.html I don''t have the xen-3.5.gz compiled . (just for my understanding ) Neither do i know how to compile it for the pvops kernel (2.6.31.6) that I am using. Can you shed some light as to how I can generate the xen.gz image , Please note that I have CONFIG_XEN_DOM0=y set in my .config file. I have attached the .config and menu.lst file for your reference. What is the significance of CONFIG_XEN_DOM0=y ? does is generate dom0 image as well ? If yes where ?? Thanks anyways for your concern. /Onkar For details on how to do that look at the URL that Boris sent - it is pretty comprehensive. Also take a look at this (which Boris wrote as well): http://bderzhavets.wordpress.com/2009/08/31/loading-xen-via-grub2-on-top-ubuntu-karmic-server-alpha-4/ That explains how to setup the GRUB2 entry correctly. Boris, I am CC-ing you on this e-mail. Any suggestions on what else he might need to do? -----Inline Attachment Follows----- _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
So that means that I am able to boot completely the dom0 right ??
