Welcome Joao! Awesome to have another person working on this stack. It's been a 
bit lonely in the middle, where there are few contributors to the libvirt Xen 
driver.

Large NUMA compute hosts running Xen could be managed similar to KVM hosts if 
the Xen stack supported the libvirt NUMA-related knobs. This might be one of the 
bigger gaps in the Xen stack compared to KVM, and AFAIK no one is working on it.
WRT snapshots, Chun Yan Liu has been working on support in Xen

http://lists.xen.org/archives/html/xen-devel/2015-01/msg03071.html

As I mentioned on the call, she has a V11 of the series ready but is awaiting 
4.7 development to open before posting it. She has also been working on support 
in libvirt based on the pending V11 series.
