- My Windows client cann’t change it’s resolution automatically, what should I do?
Check if you have a Channel with it’s type as
spicevmc and value as
com.redhat.spice.0, if it doesn’t exist,
add it, shutdown your guest, and then restart it.
- My Windows client cann’t change it’s resolution automatically in a HiDPI screen, what can I do?
edit your Windows guest description XML file in virt manager or run it in command line:
$ sudo virsh [sudo] password for jiajun: Welcome to virsh, the virtualization interactive terminal. Type: 'help' for help with commands 'quit' to quit virsh # edit --domain win
and find a section like this:
<video> <model type='qxl' ram='65536' vram='65536' vgamem='32768' heads='1' primary='yes'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x0'/> </video>
change value in vgamem=‘32768’ to 32768 or 65536, then shutdown your guest, and restart it.
