Esto es un HowTo para poder copiar una máquina virtualizada con Xen.

primer paso, hacer un respaldo de la máquina que esta en perfectas condiciones.


luego montar el archivo disk.img en alguna carpeta

#mount -o loop /home/xen/domains/xen01/disk.img /mnt/tmp

modificar el archivo /etc/xen-tools/xen-tools.conf

cambiar la configuración del método de instalación

install-method = copy

luego crear la maquina virtual.

# xen-create-image --passwd --install-source=/mnt/tmp/

luego modificar el fichero

/etc/xen/mimaquina.cfg

y cambiar file por tap:aio en la configuracion de los discos duros.


luego

#xm create nombreDeLaMaquina


y listo.

The Day the Routers Died

Gary Feldman - The Day the Routers Died

---------------------------------------
a long long time ago
i can still remember
when my laptop could connect elsewhere
and i tell you all there was a day
the network card i threw away
had a purpose - and it worked for you and me...
but 18 years completely wasted
with each address we've aggregated
the tables overflowing
the traffic just stopped flowing...

and now we're bearing all the scars
and all my traceroutes showing stars...
the packets would travel faster in cars...
the day... the routers died...

so bye bye, folks at RIPE 55
be persuaded to upgrade it or your network will die
IPv6 just makes me let out a sigh
but I s'pose we'd better give it a try
I suppose we'd better give it a try

now did you write an RFC
that dictated how we all should be
did we listen like we should that day

now you back at RIPE fifty-four
where we heard the same things months before
and the people knew they'd have to change their ways...

and we - knew that all the ISPs
could be - future proof for centuries


but that was then not now
spent too much time playing WoW

ooh there was time we sat on IRC
making jokes on how this day would be
now there's no more use for TCP
the day the routers died...

so bye bye, folks at RIPE 55
be persuaded to upgrade it or your network will die
IPv6 just makes me let out a sigh
but I s'pose we'd better give it a try
I suppose we'd better give it a try

I remember those old days I mourn
sitting in my room, downloading porn
yeah that's how it used to be...

when the packets flowed from A to B
via routers that could talk IP
There was data... that could be exchanged between you and me...

oh but - I could see you all ignore
the fact - we'd fill up IPv4

but we all lost the nerve
and we got what we deserved!

and while... we threw our network kit away
and wished we'd heard the things they say
put all our lives in disarray

the day... the routers died...

so bye bye, folks at RIPE 55
be persuaded to upgrade it or your network will die
IPv6 just makes me let out a sigh
but I s'pose we'd better give it a try
I suppose we'd better give it a try

saw a man with whom I used to peer
asked him to rescue my career
he just sighed and turned away...



I went down to the net cafe
that I used to visit everyday
but the man there said I might as well just leave...

and now we've all lost our purpose..
my cisco shares completely worthless...

no future meetings for me
at the Hotel Krasnapolsky

and the men that make us push and push
like Geoff Huston and Randy Bush
should've listened to what they told us...
The day... the routers... died

bye bye, folks at RIPE 55
be persuaded to upgrade it or your network will die
IPv6 just makes me let out a sigh
but I spose we'd better give it a try
I suppose we'd better give it a try
