Subject: lib: Prohibit parallel connections with tunneled migration
X-Git-Tag: v6.1.0-rc1~269
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e092daacee330b8f758bceaf1e9a0ccfec2e00c8;p=thirdparty%2Flibvirt.git

lib: Prohibit parallel connections with tunneled migration

As discussed on the developer list, parallel migration connections
are not compatible with tunneled migration

https://www.redhat.com/archives/libvir-list/2020-January/msg00463.html

Prohibit the concurrent use of parallel and tunneled migration options.
