Re: [Xen-users] Alpine Linux Xen Dom0 LiveCD

Hello,

Alpine Linux has just released a Xen Dom0 LiveCD that contains a Linux Kernel 3.3.6 with PaX and grsec patches and Xen 4.1.2 with the CVE fixes. This LiveCD doesn't include any kind of X11 desktop, as it is intended for server use only.

The traditional GNU/Linux base system is over 100MB in size (excluding the kernel), while the base system in Alpine Linux is only 4-5MB in size (excluding the kernel).
...
It's great for experimenting: Since the system configuration can be backed up to a single file, you will be able to test configurations before deploying them to production systems.

...

Also, Alpine Linux has the option to run from RAM, even when installed to a HDD or USB, allowing the user to save it's changes on a USB, floppy or other medium which then gets read at boot to leave the system as it was before the reboot. This is specially interesting for Xen Dom0, since it allows to have the whole system on RAM, which is immune to HDD crashes (you could have access to your Dom0 even after and HDD crash) and doesn't consume I/O resources.

This is still the first and experimental release of this LiveCD, so I would like to encourage Xen users to test it, and report back with the results.

The LiveCD can be found at: http://alpinelinux.org/downloads

Roger,

Thanks a lot for this usefull image. I'm missing however a bootable USB image. We are already in 21st century and many new systems simply don't have CD/DVD drives anymore. Most of my servers run without it as I use *only* USB sticks as boot / install media instead of slow CD/DVD based images.

Best regards, Mark
