Cloud Hosted Router (CHR) is a RouterOS version intended for running as a virtual machine. It supports the x86 64-bit architecture and can be used on most of the popular hypervisors such as VMWare, Hyper-V, VirtualBox, KVM and others. CHR has full RouterOS features enabled by default but has a different licencing model than other RouterOS versions.
p1 (perpetual-1) licence level allows CHR to run indefinitely. It is limited to 1 Gbps upload per interface. All the rest of the features provided by CHR are available without restrictions. It is possible to upgrade p1 to p10 or p-unlimited. After the upgrade is purchased the former licence will become available for later use on your account.
