Thanks for your answer,

1) In this case i'm not using shared storage, the migration is happening between two non-shared storage with full disk copy

2) I already created the file with same size, and the vm works properly after a restart, my problem that it remains paused and I can't resume it until it's rebooted.

3) I'm using qemu-kvm 1.0

I'm trying to implement a virtualization API. I was testing migration

When I use the following command :

qemu+ssh://server_ip/system*

the migration works fine but in the destination host the migrated vm is
paused and I can't unpause it and I need to reboot the vm to be able use
it in the new host. When I try to unoause it Igot the following error
message:
<< *Error unpausing domain: internal error: unable to execute QEMU
command 'cont': Resetting the Virtual Machine is required *>>

How can I solve this problem, or is there an other way to make a live
migration with libvirt??

Several things may be happening here, so I'll point just a few (unordered).

1) is there some storage shared between the two hosts? If so, is it accessible from the destination?

2) When doing storage migration, you still need to pre-create the files on destination yourself. Do they have the correct size?

3) The error message seems like a qemu bug to me. Have you tried it with recent qemu?
