hello,
Our support for hot migration and cold migration. But there are many restrictions

VM live migration may take a long time if the migrated VMs are heavily loaded or have high memory usage. Therefore, perform VM live migration during off-peak hours.
VM live migration is not supported when the VM NIC works in SR-IOV, PF, or PCI passthrough mode.
If the cloud server has a CD drive but the local CD-ROM drive or ISO image file is not mounted, live migration and cold migration are supported. When a local CD-ROM drive or ISO image file is mounted, live migration and cold migration are not supported.
Live migration requires that the source and destination hosts use the same type of hypervisor (KVM, VMware, or Xen).
VM cold migration and live migration are not supported if the virtualization type of the AZs housing the VMs is VMware.
Batch cold migration is supported if the virtualization type of the AZs housing the VMs is Xen.
If a VM using a SCSI passthrough volume has a SCSI lock, the VM cannot be live migrated.
In the Region Type I scenario, VMs created on ManageOne Operation Portal (ManageOne Tenant Portal in B2B scenarios) need to be live or cold migrated in cascaded FusionSphere OpenStack systems.
Only cross-AZ cold migration is supported, and cross-AZ live migration is not supported.
Live migration requires that the source and destination hosts use the same CPU model. If only the CPU frequencies of the source and destination hosts are different and the CPU of the destination host supports Timestamp-Counter Scaling (supported by CPUs of V5 and V6 servers), live migration can be performed.
