Re: [Xen-users] While installing guest OS, having error "Invalid kernel"

[jaeyong yoo <y.jaeyong@xxxxxxxxx>]

Hi Lan,

It worked!

I mounted the guest OS and see that the vmlinuz and initrd is not for virtualized (the filename is vmlinuz-xxx-generic). 

So I replaced them to vmlinuz-xxx-virtual (when I apt-get linux-virtual, suddenly vmlinuz-<version>-virtual poped up in my dom0 /boot directory), and then, it worked!

Thanks a lot.

Best,

 - jaeyong

No, as far as I know it does not.

I meant "consider" as in "think about and avoid", but that wasn't
especially obvious, sorry for the confusion.
