VirtualBox 5.1.10_112026_el7 headless + phpvirtualbox 5.0.5 problem.

[Valerii Vainkop]

I'm using phpvirtualbox 5.0.5 running under vbox user to control VirtualBox 5.1.10_112026_el7 on CentOS7.

I have 3 physical virtualbox servers and using multiple servers configuration in phpvirtualbox.

A couple of days ago I tried to run a backup script (from vbox user) and it failed as it ran vboxmanage list runningvms and found nothing!

At the same time vms ARE running and I can see them in phpvirtualbox interface, connect to them & etc.

Now the weird part:

I stopped one of them using poweroff in cli:

su vbox
VBoxManage controlvm "vm01" poweroff
0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%

Then started it through phpvirtualbox interface and the machine became visible in cli:

su vbox
vboxmanage list runningvms
"vm01" {8e42afc4-b74f-4c6a-b6ff-b4f6b532f596}

But now in the phpvirtualbox interface it shows the machine state as "Stopped"!

If I try to start it from there, it says:

VirtualBox error: rc=0x80bb0007 The machine 'vm01' is already locked by a session (or being locked or unlocked) (0x80bb0007)

So I stopped the vm from the cli & started it from the phpvirtualbox interface.
The progress bar on the bottom of the page froze at

0% Creating process for virtual machine "vm01" (headless)

But the vm showed up as a running one in cli:

su vbox
vboxmanage list runningvms
"vm01" {8e42afc4-b74f-4c6a-b6ff-b4f6b532f596}

But it stull has a powered off state in phpvirtualbox interface!!! :(

Everything seems to be running from the vbox user, so I really don't get what's going on here. Please help me to bring this stuff back to normal.

Thanks!
