This is my first time using Qemu, and creating my own virtual machine. I feel like a complete newb ;(
Debian Linux host Uname -a: Linux 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1+deb8u5 (2015-10-09) x86_64 GNU/Linux
Debian Linux guest VM uname-a: linux 3.16.0-4-amd64 #1 SMP debian 3.16.7.ckt11-1+deb8u5 (2015-10-09) x86_64 GNU/Linux
I've created a basic Debian Jessie VM. The install took 24hours !
My finished virtual machine works OK, but is painfully slow ! Even typing at the terminal is excruciating.
I was hoping I would be able to share this with my colleagues for a project we are working on. But if it runs this slowly they won't be impressed.
I don't even know where to begin for how to troubleshoot ?
I've read about changing the cache setting, but how do I change this ? Setting file, at start up ?
What about adjusting the VM's memory use, how can I be sure it is using a part of the hosts memory (I don't want it to use all of it, but it can certainly have a couple of gigs).
It is intended to only be a 'testing' zone, so I don't expect to have a heavy load (no game playing etc) but I do want to be able to run a LAMP stack.
One thing which didn't help is that the qemu command is different and even the official docs don't seem to mention that I should have been using qemu-system-x84-64 - thank god for SO !
Thanks in advance for your help, I know it looks like I've not done my research, but unfortunately what I have read has completely baffled me.
I created the Vm as follows
Install qemu etc:
sudo apt-get install qemu qemu-kvm libvirt-bin
Created a qcow disk (I realise this is a large disk, but I figured I should try to make things as easy as possible for my future colleages):
qemu-img create -f qcow2 debian.qcow 15G
Start the install of the new system :
qemu-system-x86_64 -hda debian.qcow -cdrom debian-8.2.0-amd64-CD-1.iso
