Xen PVonHVM can't mount rootfs

[Jean Guyader]

Hi,

I installed natty on Xen and got PVonHVM working but I've noticed that CONFIG_XEN_PLATFORM_PCI isn't build in in the kernel event if the frontends (BLKFRONT and NETFRONT) are.

That mean that before you install linux-image-virtual you have to make sure you put "xen-platform-pci" in /etc/initramfs-tools/modules.

I've checked the virtual kernel config on oneiric and CONFIG_XEN_PLATFORM_PCI is still a module.

I think this problem could be solved in two ways:
   - Make initramfs tools Xen PVonHVM aware
   - Compile CONFIG_XEN_PLATFORM_PCI built in, the frontend are built in so I think it's reasonable to have this driver built in as well.

Jean

That is fixed in Debian Squeeze

root@debian:~# grep XEN_PLATFORM_PCI /boot/config-2.6.32-5-xen-686
CONFIG_XEN_PLATFORM_PCI=y

I manually put "xen-platform-pci" in /etc/initramfs/modules and recreate the initramfs after I installed the new kernel 2.6.38-10-virtual, then I reboot and gather the info.
