I have a CentOS 7 VM on oVirt 3.5 configured as desktop.

What is the maximum display size it can get by default without particular customizations?

In my case I'm testing from a 12.1" android tablet connected over wifi+openvpn and Opaque app.

In Opaque I have a setting called

Sync remote to display resolution

My tablet resolution is 2560x1600 (btw I don't know if I can change it in Android scaling to any other resolution....)

If I mark the setting above it seems it crashes

If I deactivate it, I get a small window in upper left corner. I can change VM resolution up to 1920 and I get a bigger window, but I cannot go full screen for example...

Anu advise at oVirt side to configure a bigger display size available?

My VM has both oVirt Guest agent and spice vdagent installed ad active.

Thanks in advance,

Gianluca
