HVM virtual machines are recognized as physical machines
This article applies to:
- Acronis Backup & Recovery 10 Advanced Server Virtual Edition
(!) This article applies only to Linux + Xen configurations. This issue does not occur on Citrix Xen.
- On a Linux + Xen system (e.g. Debian+Xen), you have virtual machines with Windows operating systems in HVM (Hardware Virtual Machine) mode;
- You install Acronis Backup & Recovery 10 Agent for Windows inside virtual machine. First installation goes fine;
- When you attempt to install Acronis Backup & Recovery 10 Agent in a second HVM virtual machine, the installation fails with the following error message:
No free licenses available for this operating system
Issue in the product.
Acronis Backup & Recovery 10 License Server recognizes HVM virtual machines as physical machines and assigns physical machine licenses to them. Since Acronis Backup & Recovery 10 Advanced Server Virtual Edition allows installation only on one physical machine, license is taken by the first installation and installation of second Acronis Backup & Recovery 10 Agent for Windows is not possible.
(!) Virtual machines in paravirtualization mode are correctly recognized as virtual machines and license assignment for them is correct.
As a workaround, use virtual machines in paravirtualization mode.
Acronis Development Team is working on fixing the issue. This article will be updated once the issue is fixed.
