Re: [libvirt] question about rdma migration



Correct me if I'm wrong but locked option is pinning all VM memory in host RAM,

for example if I have a VM with 4G memory, and I want to run some QEMU code which needs to pin 500M,

I will need to lock all 4G in host memory instead of locking only 500M.

Any idea to solve my problem? 

Regards,
Roy

No, libvirt doesn't provide any way to do this. But why would you even
want to do that? RLIMIT_MEMLOCK is irrelevant when you don't lock the
memory.
