Re: [Qemu-devel] Live Migration with different block devices

[Xiongzi Ge]

Hi Paolo,

I should make it clearer. I want to use a device for caching for the guest in host A. Then after the guest migrating to Host B, there is also a device for caching in Host B.   I want to the guest can access the new cache device in Host B at first automatically. I also want the guest can access the previous cache device in Host A, if it gets a miss. Here, I may need to modify some interfaces. Is there a simple way to do this? 

Thanks a lot

Is there a good way to handle the memory in the guest via qemu?

I'm not sure what you're asking exactly, but I'm pretty sure the answer is no.

You're confusing what QEMU is doing and what the guest is doing.  And you still haven't told us what you're trying to achieve (you only told us how).
