Currently, I am not enable to set "force-legacy" to false from command
line for
virt machine.
I think, the "force-legacy" and compat_props should work the other way
around.
The "force-legacy" should be set to false by default to select a new
behaviour.
Instead of this hw_compat_4_1 should be modified to keep the old behaviour:
--- a/hw/core/machine.c
+++ b/hw/core/machine.c

GlobalProperty hw_compat_4_1[] = {
{ "virtio-pci", "x-pcie-flr-init", "off" },
+ { "virtio-mmio", "force-legacy", "on" },
};
const size_t hw_compat_4_1_len = G_N_ELEMENTS(hw_compat_4_1);
This way, one can keep the old behaviour by doing "-M virt-4.1"
Best regards,
Vasyl
