Bug description:
Hi,
We have VMs which were started with an older version than qemu 2.1
which added "cache-miss-rate" property for XBZRLECacheStats. While
trying to migrate the VM to a new host which is running a higher
version (2.3) of Qemu we got an exception:

Would it be possible to improve the JSON parser to skip the key if the value
is incorrect instead of throwing an exception? Then hopefully qemu 2.3 or
higher is able to handle the data without this property, falling back to its
default.

[Qemu-devel] [Bug 1585533] Re: cache-miss-rate / Invalid JSON
Well, to make this work we updated the libvirt code to correct such
invalid value and put a "0" in that case for the "cache-miss-rate"
value. Can someone confirm that it putting a "0" is a valid choice, or
shall we have something else?
Thanks

Marc, what distro are you running on? QEMU 2.3 is not maintained
anymore upstream, so unless you are running on Ubuntu (and then we can
reuse this bug tracker) you'll have to reopen the bug in your distro.
