If you deploy a 1C:Enterprise server to a virtual machine and then acquire server and client software licenses there, from time to time you may encounter the need to restore the licenses even if you do not move the virtual machine between hardware servers and do not change the virtual machine parameters explicitly.
Why does this happen?
Because using such a virtual environment may result in changing the key parameters to which the software licenses are bound.
For more information, see the "10.3.1.4. Key parameters" chapter in
How to avoid this?
We recommend either using a physical machine for your 1C:Enterprise server deployment, or moving at least the licensing service (part of 1C:Enterprise server functionality) to a dedicated physical machine.
For more information, see the "10.3.1.6. Software licenses and virtual machines" chapter in
An alternative to using a dedicated physical machine for the licensing service can be using a virtual machine for the licensing service whose unchangeable key parameters after acquiring the licenses you have to guarantee.
How to configure the licensing service?
