[Qemu-discuss] Latest Qemu-COLO Problems

[wenzt]

Hi Zhang，

 

I have tested COLO with qemu-3.1.0 follow
https://wiki.qemu.org/Features/COLO

 

I got this problems on PVM:

{"timestamp": {"seconds": 1550230616, "microseconds": 644348}, "event":
"STOP"}

{"timestamp": {"seconds": 1550230616, "microseconds": 719003}, "event":
"RESUME"}

{"timestamp": {"seconds": 1550230616, "microseconds": 743554}, "event":
"STOP"}

qemu-system-x86_64: Can't receive COLO message: Input/output error

{"timestamp": {"seconds": 1550230618, "microseconds": 257209}, "event":
"COLO_EXIT", "data": {"mode": "primary", "reason": "error"}}

 

 

And on SVM:
