Eric,
Thank you for reply.

Is it necessary to expose these two APIs to user application?
+ virdomainMigrateSetCapabilities
+ virdomainMigrateGetCapabilities

For qemu , the migration capabilities are "xbzrle", "rdma-pin-all",  
"auto-converge",
  "zero-blocks" and "compress".

No, these capabilities are either turned on/off based on flags passed to
virDomainMigrate3 API.

I think we need to call qemuMonitorGetMigrationCapability when 
qemuMigrationSetCompression
if the source/dest node doesn't support  'compress' capability, we need 
to stop migration if
flags contain VIR_MIGRATE_COMPRESSED (currently it stands for xbzrle, 
and Eric's previous mail

suggest we share this flag with 'compress')
