Installing Windows 7 freeze Qubes dom0

[dede]

Everytime i try to install windows 7 my qubes gui (dom0) freeze while
win7 installing.

Also listen to music in another vm is impossible.

I have a fast i5 cpu and 24gb ram. Windows HVM with 8 GB ram and 4vcores.

I installed qubes 3.2 on ssd.

So how i can prevent that? Is it qubes creates the "hdd" file for win7 ?

It seems the installation freez all other also the mouse for 5-10seconds
this every 1-2 Minutes.

Hello,

I had also strange broken screens, now I try to run the Win7 installation process alone and don't have other apps running.

But it seems very slow to me and something with the multitasking is quite odd.

Kind Regards
