Hello
On kubevirt project we are using IpV6 Kind cluster,
and trying to support migration,
but since both of the containers are on the same host
we get this error
{"component":"virt-launcher","level":"error","msg":"internal
error: Attempt
to migrate guest to the same host
32323136-3731-4247-3831-303946353338","pos":"virNetClientProgramDispatchError:172","subcomponent":"libvirt","thread":"44",
"timestamp":"2020-03-25T10:41:12.123000Z"}
Is there a way to work around this please ?
it comes of course from
https://github.com/libvirt/libvirt/blob/master/src/qemu/qemu_migration_co...
(not sure what version of libvirt i have but it shows the uuid so i guess
this is the one)
The link above points to git master, which only checks the UUID. This
was released in 6.2.0
All versions of libvirt before 6.2.0, will also check the hostname for
equality.
Since you're inside a container you should be able to set an arbitrary
hostname for each container.
For the UUID, we obtain the value from SMBIOS data tables. To override
this there is a parameter in /etc/libvirt/libvirtd.conf.
