Did you: Check the All dirs option

@mistercutter /var/crash ?

Isn't this related to crash reports?

Right-Click => Remove crash reports?

What commands did you try?

Running

xe vm-param-cleaner uuid=<vm_uuid> param-name=blocked-operations

Will unset most of the fields and in a quick test I saw that I could reboot the machine again.

Maybe setting something to false is just not enough.

Does your XO VM have an IP address in the same range as the NFS storage?

NFS doesn't need to be aware of your VLAN, that should all be a layer below.

From your XO VM, can you run:

showmount -e <freenas ip>

@LEB-ID Yes, in XO > Settings > Servers should only have a single entry.

Once connected

XO > Home > Hosts should display your 2 servers

xe vm-list

will return also your snapshots. There are several options to the command.

try grep'ing:

xe vm-list is-a-snapshot=false

This will not most definitely only show Hades.

@runevn I think that comes down to personal preference... my XCP-ng boxes have 9 NICs XD

Any solution is OK if bandwidth is not the issue.

@runevn if you aware that there is no 100% security, that's a good start.

You can have VMs in different networks on the same XCP-ng hosts, that's why you have VLANs and stuff.

Just create a VLAN "DMZ" for your publicly exposed VMs and route and firewall that in pfsense accordingly.

Since your dom0 and other VMs will be in another VLAN "Home Network" or whatever, there will not be a major issue.

I'm not sure what's the main "security" concern you want to address with your question.

2 VM's on the same XCP-ng Hosts in 2 different VLAN => not a security issue (unless a zero day flaw is found I guess).

Your pfsense might be a security issue too, if that's compromised, no matter what the setup behind looks like is exposed.

So final words on your question in the topic:
"No"

@shorian I suppose you don't have a pool with shared storage?

As I'm a dinosaur and worked with the Windows Management Tool long before XOA was around, I know it's always there as a backup for the minimal tasks AND I'm proficient on the command line as well.

The team is working on an onboard solution:
https://xcp-ng.org/docs/management.html#xo-lite

IMHO, I wouldn't dedicate real hardware to a simple task as XOA.

In my setup, I have two pools which are connected on a network level, so I have 1 XOA running on each pool, in case of dire need (which I did a couple weeks ago).

@ascar Are you sure your pfsense is working as expected?

All the errors in your code block on top don't seem related to the xentools you are trying to install?

Shouldn't it just be

pkg install xen-guest-tools

Error updating repositories doesn't seem related to your questions.

@ascar
I'm using OPNsense (a fork).

Can you check in the webinterface, under packages. I have a package "os-xen" installed, is that available? installed?

@daksol @Danp thanks, I learned something today \o/

@piety67 Do you have a lot of snapshots on the VM?

@abatex That's the problem, you can't snapshot the ISO. Try to eject it.

@abatex Do you have an ISO loaded in the virtual CD-ROM drive?
