Original GitHub issue: https://github.com/retspen/webvirtmgr/issues/314

Hi,
I run webvirtmgr to manage 2 VMs hosts, and it is installed on one of the 2 hosts.

1- When I try to move a VM from one host to the other one -> Error 500.

Here is the stack trace:

AttributeError at /instance/1/appscan/

'virConnect' object has no attribute 'migrate'

Request Method:     POST
Request URL:    http://sublime:8000/instance/1/appscan/

 '/usr/lib/python2.7/dist-packages/gtk-2.0']

2- I've tried to move both the img and the xml files from one host to the other one. It works almost, except I don't see the snapshots. Any way to manually move the whole configuration including the snapshots?

Thanks.

Can you change line 70 in file /var/www/webvirtmgr/vrtManager/instance.py:

dom.migrate(self.wvm, 0, name, None, 0)

self.wvm.migrate(dom, 0, name, None, 0)

and try to migrate again

Here is my moveTo function:

    def moveto(self, conn, name):
        dom = conn.get_instance(name)
        self.wvm.migrate(dom, 0, name, None, 0)

So it is already the good one.

Anatoly, I wrote the code is already the good one, but the migration doesn't work. Sorry if I wasn't clear enough. Please, don't close this issue.

I am understand (my English is not very good). You need update WebVirtMgr to latest version. In line 70 must be dom.migrate(self.wvm, 0, name, None, 0)

Ok, updated WebVirtMgr. Now it says "Requested operation is not valid: domain is not running". This means the VM must run to be moved?

Ok, now: "Requested operation is not valid: cannot migrate domain with 5 snapshots". So Ican't move because of the snapshots?

Related to my second question: How can I move manually, including the snapshots?
