SVM problem on Centos 7 as non-root user

[sigterm9]

Hello, I cannot manage to solve following problem for more than week: I want to use VirtualBox on my AMD system to run VMs as non-root user - final goal is to use phpvirtualbox with it. With identical software configuration, it works flawlessly on Intel core i3 system. I have put "export VBOX_HWVIRTEX_IGNORE_SVM_IN_USE=true" in /etc/profile, otherwise VirtualBox complaints about VERR_SVM_IN_USE. When I run the VM with this env.var., it runs only as root. when i try to run it as "vboxusr", which is added to appropriate user group, it stops with:

Code: Select all

[vboxusr@beta Logs]$ VBoxManage startvm DC
Waiting for VM "DC" to power on...
VBoxManage: error: The virtual machine 'DC' has terminated unexpectedly during startup with exit code 1 (0x1)
VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component MachineWrap, interface IMachine
