[Qemu-devel] [Bug 1479717] [NEW] Auto resize VM doesn't work with windows 10 guest

[jonas]

Public bug reported:

I,m using a Ubuntu 15.04 host and a windows 10 guest (both 64 bit) on a
intel i7 proc. My ubuntu system is up-to-date and I'm using QEMU
emulator version 2.2.0. I use virt-manager 1.0.1 and SPICE guest tools
0.100 are installed on the guest.

With the exactly same setup and a windows 7 guest I can set "Auto resize
VM with window" and it perfectly works. After installing SPICE in
windows 10 I can still select this box, but it doesn't work any longer.

[Jean-Pierre van Riel]

I've observed the same issue (in Ubuntu Gnome 15.04). In addition, when
I select '' from the Virtual Machine Manager, View, Scale Display, Auto
Resize VM with Window, the guest's screen starts flickering.

On Windows 10 64bit, virtio drivers and QXL installed from ISO extracted
out the RPM here: https://fedorapeople.org/groups/virt/virtio-
win/repo/latest/virtio-win-0.1.110-2.noarch.rpm. In all cases, I
installed the Windows 8.1 x64 option, given w10 drivers are not yet
included in the ISO. The windows QXL drivers haven't been updated since
July 28th (v22.33.46.473) .

There is a commit on github about windows 10 signatures here which
suggests more formal support for Windows 10 is getting closer for some
of the virtio driver set: https://github.com/crobinso/virtio-win-pkg-
scripts/commit/342a5aaf632fa11cfd2e69acf589dd00c15f72ca

Note, qxl-dod comes from http://cgit.freedesktop.org/spice/win32/qxl. I
don't see any recent commits related to Windows 10 support.

Red Hat bugzilla doesn't seem to have the auto resize VM bug noted
anywhere? Perhaps this should be propagated upstream?

[Jean-Pierre van Riel]

Should someone else stumble upon this, the way to resolve issues for now
is to not use gnome boxes, but rather remote-viewer and perhaps there's
an issue with BIOS/EFI graphics setup with Windows 10 guests?

After a lucky coincidence, flickering seems to have be resolved for me
while tweaking something else (OVMF NVRAM for EFI). It might have simply
been manually updating OVMF or adding the NVRAM / VARS piece to my VM
Win 10 guest config. I'm not sure.

What I can report:
* virt-viewer / remote-viewer, virt-manager and gnome boxes have have stopped flickering
* virt-viewer / remote-viewer are now auto-adjusting windows 10 properly to the windows size
* gnome boxes is scaling (zooming in and out) the Windows 10 display instead of auto-adjusting the guest resolution
** Unlike the Windows 10 guest, When I test a Linux VM with the spice agent installed, it auto-adjusts the guest resolution
* virt-manager is not, it's simply cropping the output

So I think something about how Gnome Boxes handles the Windows 10 guest
is inferior to the way in which remote viewer does (when EFI is used,
which does affect graphics setup). But perhaps wait till spice-agent
officially supports Windows 10 with proper drivers, given you may not
care for people like me who try their luck with the Windows 8.1 drivers
in Windows 10.

More detail on the EFI NVRAM issue?

See: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1483071
 
Hacking around a debian/ubuntu distro specific libvirt apparmor bug allowed me to use a proper OVMF nvram template to the virtual machine config, and after reconfiguring the VM to use this, the display flickering stopped, so this may be something to do with UEFI simulation and windows 10 on KVM (but given my day job as just a virtualisation user, debugging that or understanding that low level interaction is beyond me).

I shared similar info on a related bug where gnome boxes removed the ability to control scale and auto-adjust options for the spice display behaviour

Looking through old bug tickets... is this still an issue with the
latest version of QEMU? Or could we close this ticket nowadays?
