Hi Boris,

My root partition is /dev/xvda2, in kernel not PVonHVM my root partition is /dev/sda2 and a swap is /dev/sda1.

Looks like this kernel not found the second partition (the root partition).
This kernel "jump" the swap partition??

Thanks for you help.

Cheers,
Roberto

Hi all,

I try to use kernel 2.6.36.1 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.
