libvirt-manager install tips on #Debian sid

A good idea is to add yourself to libvirt group and also kvm

sudo adduser mariuz libvirt
sudo adduser mariuz kvm

the dir of /var/lib/libvirt/images is unwritable for the group libvirt (seems that is created with root.root )
so is good to make it group rw and change the owner to grup libvirt

sudo chmod g+rw /var/lib/libvirt/images/

otherwise you will get the dreaded message qemu: could not open disk image /var/lib/libvirt/images

Now i can install natty in the virtmanager

testing tccboot with qemu/kvm
TCCBOOT, a hack where TCC loads and boots a Linux kernel from source in about 10 seconds. That is to say, it is a "boot loader" which reads Linux kernel source code from disk, writes executable instructions to memory, and begins running it.

wget http://bellard.org/tcc/tccboot.iso

for realy fast booting
kvm -cdrom tccboot.iso
for slow booting and to see what parts of the kernel are compiled
qemu -cdrom tccboot.iso

you can still run linux 0.0.1 on an qemu/bochs machine , in kvm seems to crash the vm

here is the kvm crash , i should submit to them the bug

Jeos + kvm + ubuntu

this is the virtual machine i have created with qemu manager (see the previous screenshots from the blog)

I started this way
/media/MULTIMEDIA/Downloads/jeos_ubuntu$ sudo kvm -hda jeos.dsk




Ok is not so sexy but i will add xfce and flamerobin on it quite fast :)

Installing kvm for the conference

For the firebird conference i have installed jeos on an kvm based virtual machine

Here is the guide for installing kvm on ubuntu

I have installed kvm using this guide on an cpu that supports'it

Then I downloaded the ubuntu hardy version for JeOs
an generic install cd for virtual appliances

wget http://cdimage.ubuntu.com/jeos/releases/hardy/release/














ps: virtualbox failed to be installed on my intrepid box also i will try to install it at home

sick of xen or vmware/virtualbox?

you can try kvm
the next great thing in virtualization and it is included in ubuntu by default

i couldn't install vmware player on hardy so instead i installed virtualbox
and then i downloaded the jeos iso and created an new disk for it
i will call it ubuntu-firebird (4g image)

after installing it with
$sudo apt-get install virtualbox-ose
i have added myself in vboxusers
$grep vboxusers /etc/group
vboxusers:x:124:mariuz

then restarted the system
this thing is really faast , it runs at the native speed , i like it and i think i will convert my
vmware images to virtual box ones
did i mentioned that is open source too ??

soon i will test kvm on my machine
