Hello, In some cases bus driver can deassert "bus master" bit in PCI command register. The driver will no longer be able to update related registers in the device. Eventually it will cause QEMU to exit in "virtqueue_num_heads" function. Attached path that fixes the described issue. Best regards, Yan Vugenfirer. >From 3fdafbdfad676ec8479dc073cff70bf356868bfe Mon Sep 17 00:00:00 2001 From: Yan Vugenfirer <yvugenfi@redhat.com> Date: Tue, 8 Sep 2009 10:08:14 -0400 Subject: [PATCH] VirtIO: Fix QEMU crash during Windows PNP tests Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>
