debian, ubuntu under KVM really slow

I can’t remember where I found this, so, if you are the original author of this solution, say hello, with the original link 🙂

If you install a debian or an ubuntu, you can experience some bad perf.

I use virt-manager to manage my vm’s.

Simple file with some options for the QXL driver fix the problem.

[pastacode lang= »bash » manual= »nano%20%2Fusr%2Fshare%2FX11%2Fxorg.conf.d%2Fqxl.conf » message= » » highlight= » » provider= »manual »/]

Inside the file :

[pastacode lang= »bash » manual= »Section%20%22Device%22%0A%20%20%20%20Identifier%20%22qxl%22%0A%20%20%20%20Driver%20%22qxl%22%0A%20%20%20%20Option%20%22ENABLE_SURFACES%22%20%22False%22%0AEndSection » message= » » highlight= » » provider= »manual »/]

And reboot !
