Re: [Xen-users] Convert physical server to VM

[Marc Patino Gómez <mpatino@xxxxxxxxxxxx>]

Hi Jordi,

I used this method to virtualize some GNU/Linux old boxes, the only 
problem is to shutdown the machine, boot with a LiveCD and make the dd, 
depending on the size of the HD, the downtime will be a problem. In some 
days, I will use this method to virtualize some FreeBSD servers... I 
cross my fingers :)
Regards,

Marc
