That error can be from many things. For me it was that the PXE-ROM images for
the network cards were updated as well. Their size changed over the next
power-of-two size, so kvm needed to allocate less/more memory and changed
some PCI configuration registers, where the size of the ROM region is stored.
On loading the saved state those sizes were compared and failed to validate.
KVM then aborts loading the saved state with that little helpful message.
So you might want to check, if your case is similar to mine.
I diagnosed that using gdb to single step kvm until I found
hw/pci.c#get_pci_config_device() returning -EINVAL.
Hope that helps.
Sincerely
Philipp
