[libvirt] Libvirt support for migration in KVM

[Shanmuga Rajan]

Hi

I have tested migration function VirDomain object by migrating with in
localhost(for testing purpose).

System details are

KVM hypervisor.
Intel VT 64 bit centos.
libvirt 0.4.6. (compiled from source)
vs i am running is Win 2003 64 bit...
Host is also 64 bit....

but when i tried to use the migrate function of virDomain object. it
throws the following error....

libvirt.libvirtError: virDomainMigrate() failed this function is not
supported by the hypervisor: virDomainMigrate


i read in kvm wiki that they do support  migration....
Can anyone point out the problem....


here comes the python code....

>>> vsobj.migrate(conn,libvirt.VIR_MIGRATE_LIVE,None,conn.getURI(),0)
libvir: error : this function is not supported by the hypervisor:
virDomainMigrate
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "/usr/lib64/python2.4/site-packages/libvirt.py", line 301, in migrate
    if ret is None:raise libvirtError('virDomainMigrate() failed', dom=self)
libvirt.libvirtError: virDomainMigrate() failed this function is not
supported by the hypervisor: virDomainMigrate
>>>



Thanks for any suggestion
