Hello,
(Not sure if this would be better suited for libvir-list,
but here it goes!)
I filed a bug last week regarding the way in which libvirt
assigns addresses to virtio-serial ports.
https://bugzilla.redhat.com/show_bug.cgi?id=1042505
To summarize, adding more than 31 ports causes problems
because libvirt assigns them all to a single controller,
which has a max of 31 (or less if the controller has a
ports attribute).
I was wondering, in general (eg. for things other than
virtio-serial ports), are address assignments done by
libvirt considered 'best efforts' (ie. we don't guarantee
that it will work) or part of the 'promise' to the [API]
user? (Ie. it should always result in a functioning
virtual machine)
I might be interested in working on a patch for this if
it is considered worthwhile.
Cheers,
Jonathan
