Hi libvirt team,
I was trying to migrate an OpenVZ domain from one host to another host. It
seems that the live migration of OpenVZ container is there (
https://openvz.org/Migration_from_one_HN_to_another), but it haven't been
integrated to libvirt yet. In particular, I ran the following commands and
it failed:
$ sudo virsh migrate --live --verbose --undefinesource 101 openvz+ssh://
root(a)10.12.1.39/system
error: this function is not supported by the connection driver:
virDomainMigrate3
Could anyone confirm if libvirt supports live migration of OpenVZ domain.
According to http://libvirt.org/hvsupport.html, no one has ported any of
the virDomainMigrate callbacks to the openvz driver.
If yes, please let me know the correct way to do that. If no, I would
like
to know if there is a plan to add support for that. I don't mind to submit
a patch if your team likes to review it. Please let me know. Thanks.
The plan is to wait for someone to submit a patch. So go for it! You
can use qemu and libxl migration code as a guide when implementing the
callbacks in the openvz code.
