Originally this was being performed and tested without compression, both live and cold seem to be the same speed, around ~1.2gbps No explicit restrictions on the core switch, same data center, same switch. Running twin 10gb Intel X710's on Dell R630 equipment, SSD's, pretty nice rigs. Whether us

[libvirt-users] Multi-threaded virsh migrate

2018-05-07 Thread Shawn Q
Hi folk, we are using 10gb NICs with multithreaded compression. We're finding that the standard `virsh migrate` gets at most ~1.2gbps, similar to a single scp session. When we do a multipart upload with multiple scp connections we can squeeze as high as 9.6gbps. Is there was a way to get `virsh
