Post by Thorolfmay be that's true for OS/2 as guest.
Post by Marcel Mueller- The (only resonable) E1000 emulation causes the OS/2 network driver
to hang up after until reboot a few minutes of traffic.
- VMs tend to crash occasionally.
- The virtual display of headless VMs causes black screen after login
in LXDE if X11 guest additions (any version) are installed.
This all happens with OS/2-guests?
Nope. OS/2 and Linux Guests are unstable, in fact unusable. OS/2 without
network is of little use, Linux without graphics or with completely
unaccelerated graphics is of little use as well.
Post by ThorolfPost by Marcel MuellerNon of these problems ever occurred in any previous release. And I
used at least a dozen. I would not wonder if the USB emulation is
broken in 6.1 too.
So maybe the 6.1 has problems with OS/2?
It has. Even with the extremely slow AMD PCNet network card it crashed
by far too often (The VM process not the OS/2 kernel).
Post by ThorolfBecause in my use case, several Linux- and a W10-VM with a lot of
hacking-usb-devices for iot-security-testing, the USB-path-through works
very stable and reliable.
Do you have /headless/ VMs? I only have headless VMs used as virtual
desktops via RDP.
I wonder how X11 ever works. 18.04 did not work, 20.04 did not work. All
of them tested with all available virtual video emulations, and with
large video ram and with builtin guest additions from the repository as
well as with the recent ones shipped with the host VBox installation
directly from Oracle. In all cases screen painting stopped as soon as
the LXDE session started.
Only if guest additions are removed there was a picture.
Post by ThorolfEven better than with earlier versions.
I had almost no problems with previous versions over many years. OK, I
did not upgrade to every maintenance release. AFAIR there was one
maintenance release that caused VDI file corruption quite often. In this
case I downgraded. But with the next release everything was fine again.
