[ovirt-users] Very Slow Console Performance - Windows 10

[FERNANDO FREDIANI]

I have made a Export of the same VM created in oVirt to a server running 
pure qemu/KVM and which creates new VMs profiles with vram 65536 and it 
turned on the Windows 10 which run perfectly with that configuration.

Was reading some documentation that it may be possible to change the 
file /usr/share/ovirt-engine/conf/osinfo-defaults.properties in order to 
change it for the profile you want but I am not sure how these changed 
should be made if directly in that file, on another one just with custom 
configs and also how to apply them immediatelly to any new or existing 
VM ? I am pretty confident once vram is increased that should resolve 
the issue with not only Windows 10 VMs, but other as well.

Anyone can give a hint about the correct procedure to apply this change ?

Thanks in advance.
Fernando
