 All my Ubuntu 10.04 servers are using the Linux 2.6.36 compiled by me.

 Basically you should do:

 aptitude install build-essential libncurses5-dev
 wget -c http://www.kernel.org/pub/linux/kernel/v2.6/linux-
 tar xf linux-
 cd linux-
 make defconfig
 make menuconfig

  Enable Xen within the menuconfig...

 make deb-pkg
 dpkg -i ../linux-image*.deb
 update-initramfs -c -k


 PS.: You must use the GRUB1 if your dom0 is a XenServer or some old version of Xen...

 Hope to help!

Hi all,

I try to use kernel in HVM but building the drivers xen-blkfront, xenfs, platform-pci. I used Xen 4.0.2-rc1-pre and a DomU is a ubuntu 10.04 and I try with ubuntu 10.10.

In boot I receive error "Cannot find a root partition /dev/xvda2" and a prompt (initramfs) appear.

In dmesg (initramfs) appear:
blkfront: xvda: barriers enabled (tag)
 xvda: xvda1
vbd vbd-51712: 16 xlvbd_add at /local/domain/0/backend/vbd/470/51712

I try to create n initramfs, with any modules and the DomU dont boot.
I forgot something? Can someone help me?

Thanks for any help.
