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')
