<div>This could be done by modifying the mkswap script from the
shared driver. As you'll see it is just calling mkimage, so
you either use that script for mkswap with the following
modifications, or update mkimage so the changes will affect to
all volatile disks. So my proposal would be:</div>
<div><br>
</div>
<div>1.- Create a local storage area in the hosts e.g.
/var/scratch</div>
<div>2.- Update the scrtip to create the volumes in that
directory</div>
<div>3.- Link the file in /var/scratch to the path currently
used in mkimage</div>
<div>4.- Update the delete script so when a file linked to
/var/scratch is deleted it'll follow the link.</div>
<div><br>
</div>
<div>Good luck,<br>
</div>

<div>PS: OpenNebula 4.4 does also report storage size for system
DS and considers the space left to make scheduling decisions.
To apply this to 4.4 it'd need to update the monitor_ds.sh
probe to report the size of /var/scratch.</div>

Is it possible to add a swap file to a VM template
that is located/created on the fly using the local
filesystem of the hypervisor?. <br>
<br>
I think that this feature could improve performance a
lot. Sometimes is impossible to avoid VMs to write to
swap and currently all the swap files are mounted over
NFS using 0 datastore.<br>
<br>
Can you please give me a clue to achieve this feature?<br>
<br>
