There is a powerful tool shipped with libvirt called virt-install. This tool is inside the python-virtinst package and it allows us to install any GNU/Linux distribution directly from the command line. For example, the following command will create a VM and install Fedora 17 (32 bits) on it. virt-install –name f17_i686 –ram 1024 –disk path=/dev/vg_data/f17_i686,size=15 –location=”http://dl.fedoraproject.org/pub/fedora/linux/releases/17/Fedora/i386/os/” –graphics vnc The arguments are: name = name of the VM ram = amount of RAM memory on MB disk = lthe path and size of the virtual disk location = the media to install, in this case the F17 URL. graphics = the graphic card to use After running this command, we can user virt-manager to continue with the installation process graphically.

Once working as the frequency was low it wasn’t really good for my eyes but it looked[…]

Some days ago I felt some nostalgic feelings and I tried to install a red hat 6.2 version into a fedora 14 host. The installation was painfully slow, but it was completed successfully anyway. The problem is that after booting the new (not really) redhat 6..2, I got a kernel panic with the following message: “Kernel panic: Kernel compiled for Pentium+, requires TSC” after googling that, I found that one of the solutions would be recompile the old linux kernel with the option “Unsynced TSC support”, I’m to lazy to do that just for fun, I would do it if I have no choice, but I have some doubts, why the kernel in the installation cd is not failing? and, is it because my[…]
