Re: [Xen-users] ramdisk option in domU config file does not work

[David F Barrera <dfbp@xxxxxxxxxx>]

I have 1GB of memory on my machine, of which 756 are free. Whenever I
try to start a DomU with an initrd file, I get the same error that Li Ge
reported:
        Using config file "vm1.cfg".
        Error: Error creating domain: (0, 'Error')

DomU will start just fine without the initrd; however, in one case where
I have a DomU with a Reiser FS, I need to be able to use the initrd (I
know I can build support for Reiser into the kernel, but that is not the
point).
