[ovirt-users] Virsh migrate issue

[VONDRA Alain]

Hi,
Thanks for your answer, in fact I just want to have a rescue command, if I have an ovirt crash.
I was thinking that it could be a good solution using virsh on the hypervisors.
I don't have a log experience with API/shell, and seems to be heavier to use than command line.
Could you give me examples using VdsClient or API/shell for Live migration.
Thanks

you're missing the administrative tasks ovirt does on top of base libvirt. If you absolutely need/want to use a cmdline tool there is vdsClient. It's also still unsupported but it's a bit better… What problem are you trying to solve? Normally you should use API/shell for scripting, etc.

Thanks,
