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

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

Title:
Auto resize VM doesn't work with windows 10 guest
Status in QEMU:
New
Bug description:
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.
