Since it's implementation on v8.0.0-rc0, having the PCI_ERR_UNCOR_MASK set for machine types < 8.0 will cause migration to fail if the target QEMU version is < 8.0.0 :

In order to fix this, property x-pcie-err-unc-mask was introduced to control when PCI_ERR_UNCOR_MASK is enabled. This property is enabled by default, but is disabled if machine type <= 7.2.
