pc: limit 64 bit hole to 2G by default
It turns out that some 32 bit windows guests crash if 64 bit PCI hole size is >2G. Limit it to 2G for piix and q35 by default. User may override default 64-bit PCI hole size by using "pci-hole64-size" property. Examples: -global i440FX-pcihost.pci-hole64-size=4G -global q35-pcihost.pci-hole64-size=4G Reported-by: Igor Mammedov <imammedo@redhat.com>, Signed-off-by: Michael S.
