With Qemu resize and copy-paste option, Windows VM seems to be lacking all this. This can be fixed by installing the spice tools in Windows VM. To do this, head over to spice space and download the tool and enjoy your better VM experience.
Lot of times I find myself of VM that does not correctly resize the screen display and that is literally nuisance. So, here is quick and dirty fix for this.
First you need to find out information about your display with following command:
xrandr -q
And you will see output like this:
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192

With the ever increasing cost of the Hardware, the amount of physical RAM available on the system is increasing day by day. For example, couple of years back, I had a system which was very high end Desktop with 256MB RAM and today I have a 2GB RAM Desktop. So, whats the point.
The Linux systems (right word should be kernel) are desiged to use both RAM and swap partition. Swap partition is a partition on Hard disk and is used mostly like RAM. Problem is that HDD access is always slower than RAM access and hence inherently, the system will work little slower even if you have enough RAM not to use swap. The term ”swappiness” is used to determine how the kernel should try to seam-balance between the use of RAM and swap. By default, most of the distro’s have a swappiness of 60. A higher value of swappiness means that the RAM will be swapped out faster.
Continue readingIf you are used to using Qemu for doing some experiments with different distro’s then you would also understand the problem of having to do ftp/ssh to copy the files from virtual machine to local machine. Also you have to run the machine to do that. How would you like to have a application that can help you copy the files to and from the image without having to run the VM. That’s exactly what the guestfish does. How to do it, quick demo here:
