Hey guys,

got the same problem as @insightful within my 10G Cluster-Network.
I have performed a migration via CLI:

Code:
qm migrate 105 pve2 -migration_network 172.17.6.0/24 -online -migration_type insecure -force -with-local-disks
...
Code:
...
drive-scsi0: transferred 64.0 GiB of 64.0 GiB (100.00%) in 7m 50s
drive-scsi0: transferred 64.0 GiB of 64.0 GiB (100.00%) in 7m 51s, ready

wow: duration 00:24:57

BUT
(actually I know the problem)
while an migration from pve2 to pve3 with the same CLI command:

Code:
qm migrate 105 pve3 -migration_network 172.17.6.0/24 -online -migration_type insecure -force -with-local-disks

Code:
...

The first host pve1 uses HDD and SSD, and pve2 and 3 uses NVMe... I hadn't thought about it at first.
Just a field report.
Cheers
