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 \
-m 1048576 -smp 80,sockets=80,cores=1,threads=1 \
