[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Re: [Xen-users] boot DomU using Dom0 Kernel? -- Sisu
Hi,
It seems Xen is conflict with the RT-Patch. When I configured the
domain using pygrub, it cannot boot as well.
Has anyone else tried using them together?
I changed the kernel into 3.3.6 without rt-patch. This time using
bootloader="pygrub" can boot the domU OK. But the corresponding
configuration gives me the error like this:
kernel="/boot/vmlinuz-3.3.6"
error is:
