@Bastien-Nollet where is this "offline backups" check option ?

I'm aware of snapshot mode/offline, but not offline backups ?

EDIT : my bad, I found it, it's only available for FULL BACKUPS, not DELTA BACKUPS

Hi,

when pulling info by websocket XOA jsonrpc, we can have this :

So, there is a TAG attribute on networks

But nowhere to be seen in the web UI

Could we have possibility to tag networks too ? (in the XOA web UI)

Thanks

I even had a case where my XOA had multiple NICs (and multiple IPs)
The IP that it used to access NFS was not the one I expected... the debug mode of the mount nfs CLI did put that into light.

is it the case for you ?

@Bub try to manually mount the NFS share in cli on the xoa
and activate debug (-vvv if I remember)

sometimes there is more obvious reasons , and the step where it is failing that can be seen this way

try the exact cli mount that you see failing in the error log

@Bub indeed, permissions issues.

What IP do you authorize for your NFS export ?

remember, SR and ISOsr are accessed by the XCP host IP...

but, NFS Remote is accessed by XO/XOA IP address !

@coolsport00 are the HOSTs stricly identical ? VM can manually be migrated ?

is there a VM affinity in ADVANCED TAB ? is the PREVENT VM MIGRATION ENABLED ?
if possible try to shutdown the VM.

@Pief Hi, missing some info here.
does the email attached to the licence is currently registered in the XOA/UPDATES page ?

and then go to the DISK tab of this VM and take a screenshot (before removing the unnecessary DISK in the CDROM that is on a local SR of the host where this VM currently lives )

@coolsport00 said in Rolling Pool Update Not Working:

492194ea-9ad0-b759-ab20-8f72ffbb0cbb

go in the VM view list, and enter this UUID in the search bar on top.
any luck on filtering the VM ?

@coolsport00 could you click on and post the error log here ?

@Bill.Oliver license-wise should be the same.

now I think virtualisation gurus here could try to explain you what are the challenges with numa and dual sockets

i have notions, but couldnt explain quite the optimisation in xen

@bvitnik indeed, RTFM

i'm a newb on cloud-init, and should follow more this good advice !

@Bill.Oliver obvioulsy, licensing.

If you are planning to put Microsoft VMs, beware of licensing with multisockets by hosts, you have to cover them all.

By default, you should cover 16 cores with 1 Microsoft Windows Server Standard to get 2 VMs licensed.
If you get two sockets, you have to double the licensing (and add 2 packs core to attain your cores coverage...)

All licensing based on cores make you think twice when planning CPUs...

If you want to, you can go DATACENTER edition, but you still have to cover all the cores...

https://docs.xcp-ng.org/guides/create-use-custom-xcpng-ubuntu-templates/

I noticed in the documentation, they put "password:" for user password creation.

what is working for me :

plain_text_passwd: 'myverysecureplaintextpassword'

more secure, use a SHA 512 encrypted password, but with :

passwd: QChUQYy14yOv_encrypted_password_mgnEFL6TRPIsJ/4

make it encrypted with

# mkpasswd --method=SHA-512

@acebmxer on my Windows VMs with cloudbase init I use these :

version: 1
config:
  - type: physical
    name: Ethernet2
    subnets:
      - type: dhcp4

or

version: 1
config:
  - type: physical
    name: Ethernet2
    subnets:
      - type: static
        address: 10.x.x.x
        netmask: 255.255.255.0
        gateway: 10.x.x.x
        dns_nameservers:
          - 10.x.x.x
          - 8.8.8.8

beware of TYPE, i put dhcp4, not dhcp
and the NAME of your nic needs to be exactly the one of the template !
IPs are obsfucated with x.x.x in the static version

@acebmxer said in Custom config / cloud-init:

#cloud-config
hostname: {name}
users:

• name: newusername
  gecos: New User
  sudo: ALL=(ALL) NOPASSWD:ALL
  groups: users, admin
  shell: /bin/bash
  ssh_authorized_keys:
  • ssh-ed25519 AAAAC3....18ZbA

thank you for that, I stole your user creation and SSH Key attribution with cloudinit config, it's working perfect

@joeymorin try to check the merge backup synchronously to avoid other jobs messing with this one ?

@nikade to be noted, on XO6 this bug does not exist anymore !

@bvitnik stack-wise we had the equivalent on vmware (esxi hosts, pfsenses, way of managing vlans to isolate tenants) but was all manually managed.

XOA apis/websockets possibilities and our willing to do less "by hand" put us to dev this GUI, all from scratch.
we are a small team, the more it runs by itself, the more time we have to "get it done" on other topics (sell it, market it, ...)
