qxl_ram_set_dirty: Assertion `offset < qxl-vga.vram_size' failed.

["Mr.Pine" <pine5514@xxxxxxxxx>]

Hi

I got this error msg when try to start my vm with qxl display driver ... (vm start until spice vdagent wants to auto resize screen)

This error raised when I enabled huge page on my host. I want to use huge page as back-end for my win10-64 .

/builddir/build/BUILD/qemu-kvm-0.12.1.2/hw/qxl.c:442: qxl_ram_set_dirty: Assertion `offset < qxl-vga.vram_size' failed.

here is my configuration:

host: 

centos 6.9(with kernel: 2.6.32-696.el6.x86_64)

qemu-kvm-0.12.1.2-2.503.el6.x86_64

guest:

win10 64 bit

installed Windows guest tools latest version.

Any Idea?!
