Hi, all I migrate a vm from source host to the destination host. I am sure every part is ok for migration. 1 Create the image in the destination and change the user and group. 2 Open TCP socket in the destination host. and I migrate in the source host command line. But I get the error $ virsh migrate --live --copy-storage-all vmubuntu qemu+ssh://destinationHost/system --verbose "error: operation failed : failed to retrieve chardev info inqemu with 'info chardev'" In the destination I find in the vmubuntu.log The error is "Migration failed. Exit code tcp:0.0.0.0:49170(-98),exiting." What can I do to solve it ? I do not understand how the error comes. Anyone can help me ? Thanks in advance. _______________________________________________ libvirt-users mailing list libvirt-users(a)redhat.com https://www.redhat.com/mailman/listinfo/libvirt-users

In the destination I find in the vmubuntu.log The error is "Migration failed. Exit code tcp:0.0.0.0:49170(-98),exiting." What can I do to solve it ? I do not understand how the error comes. Anyone can help me ? Thanks in advance.

Oh, I think I can describe the problem more specific. 1 Creat the vm in the source host and it run well. 2 Create the image in the destination and change the user and group

3 Open TCP socket in the destination host.

In the source host I use the different command as 1 $ virsh migrate --live --copy-storage-all vmubuntu qemu+ssh://destinationHost/system --verbose This situation, the error is: In the source host: error:operation failed:migration job:unexpectedly failed In the destiantion host: (from the vm.log) qemu:Warning: error while loading State ID section 2 <http://blog.chinaunix.net/space.php?uid=26284395&do=blog&id=29806... 2 $ virsh migrate --live --copy-storage-all vmubuntu qemu+ssh://destinationHost/system tcp://destinationHost:49170 --verbose This situation, the error is: In the source host: > error: operation failed : failed to retrieve chardev info inqemu with 'info chardev' In the destiantion host: (from the vm.log) > Migration failed. Exit code tcp:0.0.0.0:49170(-98),exiting. Can you help me ? I google the error on the www . But I can not find the proper solutions or the same questions. Thanks very much.
