[arch-general] KVM - *ERROR* failed to allocate VRAM BO?

[David C. Rankin]

Arch devs,

  I'm receiving an error with KVM (arch guest). The guest installed fine from
the 20161001 install media, but between every command, I receive the following
error:

[TTM] Byffer eviction failed
qxl 0000:00:02:0: object_init failed for (402650032, 0x00000001)
[drm:qxl_alloc_bo_reserved [qxl1] *ERROR* failed to allocate VRAM BO

  The guest has 8G of storage gcow2 (default virt-manager settings, except scale
on resize of window), 2-cores, 4G of RAM and the partitioning is all on a single
/ partition. I'm new to KVM and not sure whether this is something I should
chase though my hardware (BIOS settings, etc.) or whether this is a KVM issue,
the hardware is:

AMD FX-8350 Black Vishera 8-Core 4.0GHz/32G of RAM/Gigabyte GA-990FXA-UD3

I've followed:

  https://wiki.archlinux.org/index.php/Libvirt
  https://wiki.archlinux.org/index.php/KVM
  https://wiki.archlinux.org/index.php/QEMU

Where do I start in chasing this down? Did I miss a module?
