Hi Yaniv,<br>
<br>
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.<br>
<br>
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.<br>
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.<br>
<br>
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.<br>
<br>
Regards,<br>
Fernando<br>

there,<br>
<br>
With oVirt 4.0 Release is running oVirt Node in a SD Card or
USB Stick supported where the system boots in memory and
only writes configuration changes to permanent storage
similar to what VMware ESXi does ?<br>
<br>
This is very useful and can save a significant amount on
CAPEX and running costs depending on the size of the
cluster.<br>
<br>
Thanks<br>
Fernando<br>
