Hi,I am use virsh and test the migration command, on server.example.com: # rpm -qa|grep libvirt libvirt-0.9.10-21.el6.x86_64 libvirt-python-0.9.10-21.el6.x86_64 libvirt-client-0.9.10-21.el6.x86_64 # virsh version Compiled against library: libvir 0.9.10 Using library: libvir 0.9.10 Using API: QEMU 0.9.10 Running hypervisor: QEMU 0.14.1 #cat /etc/libvirt/libvirt.conf uri_aliases = [ "host1=qemu+ssh://root@host1.example.com/system", ] node1.example.com is the same version with server.example.com and on both server has the same storage pool with same path, first step,as use the local storage,i copied the vm win7's disk from server.example.com to node1.example.com's storage pool,and did a pool-refresh. 2nd step: on server.example.com i use this command to do the migration job: #virsh start win7 # virsh migrate win7 host1 --copy-storage-inc --persistent --live --unsafe when the migation process begin ,i can see the win7 appear on the node1.example.com whos status is paused,but just after a few secs,errs come out: (server.example.com) # virsh migrate win7 host1 --copy-storage-inc --persistent --live --unsafe error: operation failed: migration job: unexpectedly failed error: Reconnected to the hypervisor i've tried to solve this problem, but failed. thanks.
