Original GitHub issue: https://github.com/retspen/webvirtmgr/issues/277

I have several virtual machines with VirtFS mounted directories in mapped mode. When I try to save them in WebVirtMgr with the save button, I get a migration error:

internal error: unable to execute QEMU command 'migrate': Migration is disabled when VirtFS export path '/my/shared/path' is mounted in the guest using mount_tag 'myshare'

It looks like webvirtmgr is doing a managed save (/webvirtmgr/vrtManager/instance.py:52):

    def managedsave(self, name):
        dom = self.get_instance(name)
        dom.managedSave(0)

Is managedSave() performing a "migration" to a file or something? The error message seems odd. I may attempt to use the non-managed save() method and specify a file name to see if that works. Any ideas why managedsave would throw this error?

This is error you get from libvirt (qemu) WebVirtMgr only tranmit this error. Can you explain this action in console?

As far as I can tell, this looks like an issue with pylibvirt or libvirt/qemu, not webvirtmgr. Feel free to close this issue.
