[ovirt-users] Run oVirt Node in SD Card/USB Stick

[Fernando Frediani]

Hi Yaniv,

I have already done a fair amount of tunning to run a minimal OS from a 
USB stick and it seems to work reasonable well overtime, but nothing 
rock solid and of course I wouldn't try it myself in a production oVirt 
Node if that's not official.

Even if it's not running in memory it's just a question to create a 
schema to avoid all unnecessary writes to permanent storage. Logs can be 
limited to a short period in memory (in another Console) or sent to a 
remote syslog server. It doesn't change much for the base OS to read 
anything it needs.
I thought I had seen these years ago during the development of the first 
versions of oVirt Node, but maybe I misunderstood or it was not 
considered for newer versions.

Perhaps there is something around this on some roadmap. As I mentioned, 
this is a significant saving for any platform not having to use any 
disks in the Compute Nodes.

Regards,
Fernando
