Create a new VM on XEN 4

For Windows VMs

• Create a new harddisk in /home/xen_disk (or reuse an existing one)
  dd if=/dev/zero of= /home/xen/domains/win01/disk.img bs=1M count=15096
• Copy/Paste a domain config file and change basic things:
  • MAC adress
  • disk file
  • vnc settings
  • cd drive on iso...
• And launch it with a 'xm create win01'

For Linux VMs

• Get an i386 kernel, because I want to run 32 bits DomU on my x64 Dom0 :
  • Download a i386 kernel version
    wget http://ftp.fr.debian.org/debian/pool/main/l/linux-2.6/linux-image-2.6.32-5-xen-686_2.6.32-37_i386.deb
  • Unpack it, without installing it (he don't want to install because not the same arch)
    dpkg -X linux-image-2.6.32-5-xen-686_2.6.32-37_i386.deb /
  • Create the initrd ram fs:
    update-initramfs -c -k 2.6.32-5-xen-686

• Create your VM with xen-tools:
  xen-create-image --hostname lin01 --dhcp --vcpus 1 --dir /home/xen_disk --arch=i386 --size=15Gb --noswap --memory=1024Mb  --kernel=/boot/vmlinuz-2.6.32-5-xen-686 --initrd /boot/initrd.img-2.6.32-5-xen-686

• Start it :)
  xm create lin01
