Trying to get a better understanding of the live migration process. I notice that in my clusters when using live migration, it hits 32.5MB/s and hits a wall. This is far from the speeds which I should be seeing. Utilizing ssh/rsync and cipher arcfour, I have no issues pulling 150-170MB/s (10GB backend).
Looking at top during the migration and the ssh process isn't working to hard, 15-20%, plenty of room for more speed. Is there anything which could limit this speed? I have VM's with 50+GB, takes forever to migrate them at 32.5MB/s. I appreciate the input.
Should I see the cipher set in this string?
/usr/bin/ssh -o BatchMode=yes root@10.211.46.1 -L 60000:localhost:60000 qm mtunnel
