Hi guys,   yesterday I installed the Virtual Machine Manager on my Xpenology machine (DS918+, DSM 6.2.1-23824 Update 4, 1.04b Loader). I've got Asus Prime J3355I-C with 8 GB RAM.  I tried VM's with Windows 10 and Ubuntu. The Log says the following:  Failed to power on the virtual machine [Ubuntu] on the host [Synology].   Do you have any ideas which I could test? Thanks in advance. Pascal
