<hr />
<div>= Introduction =<br />
<br />
We will reserve some time for people to get together and discuss<br />
strategic decisions as well as other topics that are best solved within<br />
smaller groups. This time can also be used for hands-on hacking<br />
sessions.<br />
<br />
If you are interested in organizing such a group time event, please add<br />
it to the list '''before''' KVM Forum, so people have time to organize which<br />
one they will attend.<br />
<br />
Adding links to this wiki is restricted. If you have problems adding your<br />
BoF, please send it to the program committee at <br />
[mailto:kvm-forum-2018-pc@redhat.com kvm-forum-2018-pc@redhat.com].<br />

=== Better Speculative-Execution/L1TF Mitigations ===<br />
<br />
'''Summary:''' Doing a better job of mitigating speculative-execution-based attacks<br />
<br />
Diving into how we can better mitigate speculative-execution attacks in the context of KVM. Issues include (feel free to add your own):<br />
<br />
* Reducing the reachable Direct Map<br />
* Hyperthreading Issues<br />
* ...<br />

=== multi-process QEMU ===<br />
<br />
'''Summary:''' Examining separation of emulated IO devices into separate processes<br />
<br />
Marc-Andre Lureau & Konrad Rzeszutek Wilk presented the concept of a multi-process<br />
QEMU at KVM Forum 2017. The idea is to dis-aggregate QEMU into multiple processes<br />
for benefits discussed below. [https://lists.gnu.org/archive/html/qemu-devel/2018-10/msg02689.html Patches] which provide an idea of this concept have been<br />
sent to qemu-devel@nongnu.org.<br />
<br />
Very much looking forward to picking your brain regarding this topic.<br />
<br />
Benefits of dis-aggregating QEMU into multiple processes:<br />
* Reducing the impact of malicious software; tailored SELinux policies<br />
* Modularity<br />

=== Cross-architecture education ===<br />
<br />
'''Summary:''' Explaining architecture specific things to other architecture maintainers<br />
<br />
There are many interfaces and features that are architecture specific. <br />
We need to spread the word about what and why we are doing things to improve KVM across all architectures. <br />
