us](doc/how-to-get-help). Also note that we also accept virtual

machine "donations" now, for which requirements are different, see

below.

## Must have

 * proprietary Java/ActiveX remote consoles

 * hardware RAID, unless supported with open drivers in the mainline

   Linux kernel and userland utilities

# Virtual machines requirements

## Must have

Without those, we will have to be basically convinced to accept those

machines:

 * Debian OS

 * Shell access (over SSH)

 * Unattended reboots or upgrades

The latter might require more explanations. It means the machine can

be rebooted without intervention of an operator. It seems trivial, but

some setups make that difficult. This is essential so that we can

apply Linux kernel upgrades. Alternatively, manual reboots are

acceptable if such security upgrades are automatically applied.

## Nice to have

Those we would have in an ideal world, but are not deal breakers:

 * Full disk encryption

 * Rescue OS boot to install our own OS

 * Remote console

 * Provisionning API (cloud-init, openstack, etc)

 * Reverse DNS

 * Real IP address (no NAT)

## To avoid

Those are basically deal breakers, but we have been known to accept

those situations as well, in extreme cases:

 * No control over the running kernel

 * Proprietary drivers
