[ovirt-users] ovirt on sdcard?

[FERNANDO FREDIANI]

The proposed seems to be something interesting but is manual and 
susceptible to errors. I would much rather if this would come out of the 
box as it is VMware ESXi.

A 'squashfs' type of image boots up and runs completely in memory. Any 
logging is written and rotated also in memory which keeps only a certain 
recent period of logs necessary for quick trobleshooting. Whoever wants 
more than that can easily set a rsyslog server to collect and keep the 
logs for a longer period. With this, only the modified Node 
configuration is written in the SD Card/USB Stick when it changes which 
is not often which makes it a reliable solution.

I personally have a Linux + libvirt solution installed and running in a 
USB Stick that does exactlly this (writes up all the logs in memory) and 
it has been running for 3+ years without any issues.
