[Qemu-devel] OS crash while attempting to boot a 1TB guest.

[Chegu Vinod]

Hello,
For guest sizes >= 1TB RAM  the guest OS is unable to boot up (please 
see attached GIF file for the Oops message). Wonder if this is a 
bug/regression in qemu/seabios or does one have to enable/disable 
something else in the qemu command line (pl. see below) ?

Thanks
Vinod


Host and Guest OS : 3.10-rc2 (from kvm.git) and qemu1.5.5 (from qemu.git 
as of May 28th)

The qemu command line :


/usr/local/bin/qemu-system-x86_64 \
-enable-kvm \
-cpu host \
-name vm1 \
