hi,
Please consider the below situation.
we want to migrate vm1 from compute1 to compute2

vm1 is being hosted on cpmpute1 node and it has a volume attached on compute2.  
vm2 is being hosted on compute2 node and it has a volume attached on compute1.

we have an application on the these two instances which is accessing these volumes. in the nova.conf we dont have the VIR_MIGRATE_TUNNELLED option. we are now trying to live migrate one instance with block migrate option . the libvirtd.log is having the below mentioned errors.

we have tried migration with out running the application and it is working fine. what could be the reasons?
