V2V on ESXI to Hyper-v extremely slow
Posted: Sun Aug 23, 2020 3:33 pm
I've attempted the conversion twice now from an intermediary machine and directly from the Hyper-v host. In my last attempt, I connected directly to the 6.5 ESXi host from the hyper-v server with the V2V software. Both system are running on gigabit copper to the same switch. I have tested speed between both machines just using windows which is not exactly efficient and it was able to transfer data 10x faster than the V2V converter. I monitored the CPU and Memory remotely for a few minutes and they were hardly doing anything. The network was showing 96 mb/s the remote connection tested when not migrating was 32 kbps at its max so remote monitoring wasn't using much of the network bandwidth. The VM had a 33 GB vmdk boot file and a 299 GB vmdk data file. The 33 GB file took 2 hours 10 minutes. In the second file, I stopped at 25% after 14 hours since it wouldn't finish by the deadline. My first test produced the same results but was marginally slower on the intermediary machine. Even though the system shows a 96 Mb/s receiving speed after calculation it was really only 1.5 Mb/s. I'm hoping I'm doing something wrong because this seems strange it takes so long to do the migration.
