I have a slight problem with my GPU. It happend on Debian 9.8, so i’ve moved into OpenSUSE tumbleweed. The same problem… So what is it?
It’s that… when i create virtual machine, i give it disks, set CPU, add PCI GPU and launch the setup for the first time everything seems to work on virt-manager. My screen is working because picture is visible on my monitor, i can install Windows 10, reboot and it all works good. The problem begins when i shutdown VM, then start it back on and the screen is black until Windows welcome screen appears… THEN monitor turns on, but the problem is even worse when i want to install windows again on created VM. Screen is always black (wheter it is on installation disk, or i just launch windows already installed). So it seems like the driver is enabling somehow my GPU when windows is started? Where is the problem? I will paste here my VM config.
linux-xviy:~ # cat /etc/libvirt/qemu/win10.xmlwin10 3ba63d23-4eb1-41e5-a987-20e8ee5be36e 8392704 8392704 8 hvm /usr/share/qemu/ovmf-x86_64-ms-code.bin /var/lib/libvirt/qemu/nvram/win10_VARS.fd destroy restart destroy /usr/bin/qemu-system-x86_64
So for the record… When i install Windows with first-ever created VM, the monitor shows everything… When i stop vm and start it again, the screen is black until Windows Welcome screen appears (and only when AMD driver is installed, because when it’s not, screen is always black).
