Hi there! Although the guest has 2GB memory, the windows guest was adjusted to support this.
I guess that the LVM is the best choice! I will save all images to other disk and re-build the partition with LVM. Do you recomend to use ext4 or zfs ? - About the apparmor, I have my doubts, I will try to disable and see what will happen! - About the tablet input device, I removed! Some forums say that consuming idle cpu time. - About the guest agent, I have installed, but the first service can´t start! The error says: *A timeout was reached (30000 milliseconds) while waiting for the QEMU Guest Agent service to connect.* [image: Imagem inline 1] I´m using the virtio-win-0.1.117.iso, but I don´t know if this is updated. Thanks for your reply and your help!
