RE: [Xen-users] XCP PV boot process

[Dave Scott <Dave.Scott@xxxxxxxxxxxxx>]

Hi,

I'm afraid the docs are lagging behind the code a bit here.

I think to fix your "illegal kernel path" problem you have to make a directory

/boot/guest

And create a symlink inside pointing to the kernel you want. Then you can set 
PV-kernel to /boot/guest/kernelname.

Dom0 kernel (and initrd) paths were restricted as part of the RBAC work. 
Previously any file in dom0's filesystem could be a kernel or ramdisk. Now it's 
only a specified subset of files.

HTH,
Dave
