From: Shmulik Ladkani Date: Sun, 13 Dec 2015 08:08:32 +0000 (+0200) Subject: vmw_pvscsi: Introduce 'x-disable-pcie' backword compatability property X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d5da3ef;p=qemu.git vmw_pvscsi: Introduce 'x-disable-pcie' backword compatability property Following the previous patch which changed pvscsi to be a pci express device, this patch introduces a boolean property 'x-disable-pcie'. Its default value is false, exposing pvscsi as a pcie device. Setting 'x-disable-pcie' to 'on' preserves the old 'pci device' (non express) behavior. This allows migration to older versions.
