The continuing challenges of getting a workable server continue. The latest spins of VirtualBox seem to have solved the issues of DKMS auto compiles of the driver being aborted. The yum updates work as expected, provided one stops the running vms manually first.
However, trying to get systemd to start the vms is proving to be a PITA. I have extensively googled and found that there are no specific instructions for Fedora/Redhat/CentOS and VirtualBox setups for systemd. After many trials and errors I have this systemd service file:
filename - /etc/systemd/system/vboxstarter@.service
[Unit] Description=VBox Virtual Machine %i Service Requires=systemd-modules-load.service vboxballoonctrl-service.service After=systemd-modules-load.service vboxballoonctrl-service.service Conflicts=shutdown.target
[Service] User=<username> Group=vboxusers Restart=on-failure TimeoutSec=5min Environment="VBOX_USER_HOME=/home/rkampen/VirtualBox VMs/%i" ExecStart=/usr/bin/VBoxHeadless -s %i ExecStop=/usr/bin/VBoxManage controlvm %i savestate
[Install] WantedBy=multi-user.target
and on occasions the invocation systemctl start vboxvmstarter@Windoze10_2.service will work, although recently it is failing always with
$ systemctl status vboxvmstarter@Windoze10_2.service

as <username> a vboxmanage list vms "Windoze10_2" {51c8f956-9aba-4d2a-942c-8f46889d5bc0}
shows the required vm. as root or using sudo it returns nothing. thus my only conclusion is that systemd actually runs this as root and ignores the User= line of the [Service] stanza.
No idea where to from here, so if there is anyone that has a working systemd autostart VirtualBox setup on a headless CentOS 7 server - please advise what you have done to get it working. Or any systemd gurus that can point me at the specific foo required to beat this deamon into submission. TIA Rob P.S. I deliberately set up the VirtualBox vms under a non privileged user account. I have tried setting up a symbolic link from /root to the ~/username/VirtualBox\ VMs folder and made root a member of the virtualboxusers group - no difference, as expected, but getting desperate.
