# Ohai Release Notes:
### Virtualization
Chained virtualization systems, such as containers running on virtual machines, can now be tracked in
node[:virtualization][:systems]. This is in addition to the former system under node[:virtualization][:role] and
node[:virtualization][:system]. For example, a node could have all of these attributes at once:
```
node[:virtualization][:system] = "vmware"
node[:virtualization][:role] = "guest"
node[:virtualization][:systems][:lxc] = "host"
node[:virtualization][:systems][:vmware] = "guest"
```
Due to the requirements for being an LXC host being easily fulfilled, we only
populate the old system (role & system) with LXC if there are no other virtualization systems detected.
### Miscellaneous
* Ohai now collects mdadm RAID information.
* Ohai know uses lsblk, if available, instead of blkid
* linux::filesystem now reads all of /proc/mounts instead of just 4K
* linux::network now handles ECMP routes
