[Fixed] Won't start on Solaris 11.3

[bqbauer]

As usual and necessary, I uninstalled the old version, installed the new along with the additions. The main GUI won't open. Something flashes up and then goes away. I rebooted, same results. Two log files attached.

However, VM shortcuts do start and display normally so far.

I understand it's not necessarily an easy fix, but are we going to see Windows 8 and Windows 10 guests being able to run in seamless mode with 5.1? These guests still paint their desktop over the host and hide all host windows when a guest window is brought forward. Attaching a log for that VM after attempting seamless mode with Windows 10 Pro.

Same appearance on Fedora-24: Dies immediately when trying to start.

I tried to strace VirtualBox on Fedora-24. The result is attached (Attachment is file vb.str). Additionally, during strace a popup appears. It is attached too (file 'Screenshot from 2016-06-04 14-13-58.png')

See attachment for strace

moved my thread to here as seems to be the same issue on Debian Stretch (root access, not qt5).

I get a quick flash of the beta warning and it segfaults when running from the terminal, if i run strace i at least get a proper error box popping up:

vbox510.png (28.01 KiB) Viewed 6744 times

$ uname -a
Linux mypc 4.5.0-2-amd64 #1 SMP Debian 4.5.5-1 (2016-05-29) x86_64 GNU/Linux

also, the debian package doesn't seem to handle obsoleting old versions properly - i had to uninstall 5.0.20 before i could install the beta.

looks like its ignoring the vboxusers group and demanding it be run as root:

Same Qt startup issue on dev builds 99 and 100. 5.0.20 and 5.0.21-107750 don't
fail on startup.

[michaln]

Yes, it's broken on Linux and Solaris. The beta popup dialog destroys things.

It should be possible to start VMs with 'VirtualBox --startvm <vm>'.

[backes]

Sorry, but doesn't help. Still crashes with another errror message! (Fedora 24, See attachment)

[backes]

Details: Failed to start the virtual machine win7.

No more handles available, too many open handles. (VERR_NO_MORE_HANDLES).

Result Code: NS_ERROR_FAILURE (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

[backes]

Installation of http://download.virtualbox.org/virtualbox/5.1.0_BETA2 (FEdora-24) does not help. Getting an error message like:

[frank]

backes, the VERR_NO_MORE_HANDLES error is a different issue which can be worked around by disabling audio for this VM. We are aware of this error and trying to fix it. The original issue in this thread is most likely fixed with Beta 2.

[frank]

See this thread.

[backes]

Indeed, disabling audio allows to start BETA1 properly. Thanks for the hint!

[frank]

I will mark this defect as 'Fixed' because I believe that the original issue (VM selector wouldn't start) is fixed with Beta 2.
