Hi Abhishek,
If I look at the latest hvsupport.html, it still shows virDomainMigrate as unsupported by QEMU/KVM.
I did some more search and if I look at the log ( http://git.et.redhat.com/?p=libvirt.git;a=log;h=2bfdcfda7c55c3ed59c16e82fcba... ) , I see an entry for "Fix URI check in QEMU migration" which means that the support for QEMU is there.
However, Is there a definite way to confirm this support for QEMU/KVM ?
The definitive way to find it out is through the code and it is as below: 5155 NULL, /* domainMigratePrepare (v1) */ 5156 qemudDomainMigratePerform, /* domainMigratePerform */ 5157 NULL, /* domainMigrateFinish */ 5158 qemudDomainBlockStats, /* domainBlockStats */ 5159 qemudDomainInterfaceStats, /* domainInterfaceStats */ 5160 qemudDomainBlockPeek, /* domainBlockPeek */ 5161 qemudDomainMemoryPeek, /* domainMemoryPeek */ 5169 qemudDomainEventRegister, /* domainEventRegister */ 5170 qemudDomainEventDeregister, /* domainEventDeregister */ 5171 qemudDomainMigratePrepare2, /* domainMigratePrepare2 */ 5172 qemudDomainMigrateFinish2, /* domainMigrateFinish2 */ if you see, qemudDomainMigratePrepare2, qemudDomainMigrateFinish2 and qemudDomainMigratePerform are there but others are null. so if you need these then if would be ok but if you need the other functions which are currently still null then, either you have to hack it ;) or wait till some one does :) Regards, Pritesh
