I made a list of processes with a small bash script that I am attaching here

Hi,

Hello, I have installed a small system with some virtual machines. I have noticed that some processes tend to swap despite there being free RAM.
I have been unable to understand why this is happening. Has anyone else had the same experience and can help me understand?
Thank you.
Luca
I have attached a screenshot of the top command with the swap column sorted.

P.S. The system is xcp-ng 8.3 with all the latest updates.

Thank's Olivier,
So if I understand correctly I can't use it xva.py to convert and install directly.
Ok, I test today this way.

@olivierlambert
Yes, Centos 6
this a example for my VM config
disk=[ 'tap:aio:/dati/xen/asterisk/asterisk.raw,xvda,w', 'tap:aio:/dati/xen/asterisk/asteriskDati.raw,xvdb,w', ]

@olivierlambert
what you say is correct.
The files was created with dd command and mounted in vm machine for extra space

Hi,
I have some vm in xen system with centos 6 on OLD server dell.
It's time to replace the old servers and I'm considering switching to xcp-ng.
My VMs have a lot of raw data files. How can I also import the other data files of my VMs?
Thanks for your help
Luca
