<div>Hello, I am using openstack rdo with kvm libvirt.</div><div>
<span lang="en"><span><span>Live migration is very slow when the vm is using ram intensively.</span></span><span><span>
</span></span><span><span>If I migrate a vm that has been running on a host for a few days, it takes several minutes to migrate the memory.</span></span><span><span>
</span></span><span><span>After the first migration, I immediately try another one on the same vm, it takes very little.</span></span><span><span>
</span></span><span><span>I think it's due to the fragmentation of the pages: is there any remedy?</span></span></span></div><div><span lang="en"><span><span>Thanks</span></span></span></div><font color="#888888"><div><span lang="en"><span><span>Ignazio</span></span></span></div></font>
