Subject: [Qemu-devel] [PATCH] Increase maximum kernel size allowed by -kernel and -initrd
Date: Sun, 30 Apr 2006 20:16:19 -0700 [thread overview]
Message-ID: <c1bf1cf0604302016w1631d90cl7ff132e6fb4caefb@mail.gmail.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 486 bytes --]
qemu fails to boot recent releases of Fedora Core with the
-kernel/-initrd options, since the kernel is large enough to overrun
the space allocated to it by qemu's built-in bootloader.
The attached patch simply moves the base address of the initrd to a
higher location, which allows sufficient space for a larger kernel.
Ideally qemu would figure out where to load the initrd based on the
size of the kernel, but I hope this patch is simple enough to solve
the problem for now.
