Creating a Virtual Machine from an Existing one Manually
Back to: Xen on Debian
Assuming an LVM setup, this is the command for allocating the required disk space (in this example 20Gb) for the main disk of the virtual machine. Another ammount is required for the swap space.
where machine-name and volumegroup-name are specific to the intended configuration.
The virtual units are formatted
mkfs.ext4 /dev/VG1/machine-name mkswap /dev/VG1/machine-name-swap
After the file copy, it is necessary to edit some configuration files: securetty, inittab and fstab
vi securetty
hvc0
vi inittab
c1:12345:respawn:/sbin/agetty 38400 hvc0 linux
- c1:12345:respawn:/sbin/agetty 38400 tty1 linux
vi fstab
/dev/xvda1 / ext3 defaults 1 1
/dev/xvda4 swap swap defaults 0 0
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0
cd /dev
