+ Windows HV Support: https://bugzilla.redhat.com/show_bug.cgi?id=1125297
Just to note you can do this today by either:
- vdsm custom hook
- change of engine config if you know your hosts are only 7.0
- iirc, also possible by editing the specific osinfo config file to add the flags there
Without these flags, my testing shows a completely idle 4 vcpu win
slave
uses ~15% of a host core, which limits overcommit ability. With them it
goes down to 3.6% in my testing. hv_relaxed on its own shows no
improvement over idle time.
Unfortunately there is a KVM kernel bug that leads to win hangs with
these flags, and so until RHEL gets 3.16, which looks like 7.1, only Fedora works:
https://bugzilla.redhat.com/show_bug.cgi?id=1091818
+ Ability to add local storage without putting the host in maintenance mode
This should work today. Only the wizard to 'configure local storage' requires this
at it performs create DC, create cluster, move host to new cluster, add storage domain.
The 'move host to new cluster' requires host to be in maint. Adding another local
domain. Should not require this.
+ Some out-of-the-box option for self-hosted engine without shared
storage
(e.g. gluser, ceph, drdb, application directed replication, etc)
Focus here will be gluster for 3.6

Awesome. Thanks for the tip.

This should work today. Only the wizard to 'configure local storage' requires
this at it performs create DC, create cluster, move host to new cluster, add storage
domain.
The 'move host to new cluster' requires host to be in maint. Adding another local
domain. Should not require this.
AFAICT this ultimately leads to the same issue. The host actively running the hosted
engine can't add and make use of its local storage. You have to have at least two
hosts, and fail over the hosted agent. Unless of course I am missing something..

Ok but it would be great to have a solution that works with 2 hosts as well, at least
eventually.

Itamar
