@olivierlambert Just updated my post with the BIOS vs. UEFI Time to login. Both hypervisors are equally fast with EUFI, although Ubuntu 22.04 on proxmox is now slightly slower. But I guess that is not realy relevant.

RE: VM’s Slow booting
@olivierlambert Out of curiosity, I carried out a few tests this weekend. My tests are not really scientific and must be taken with a grain of salt. I started with the bare metal installs, followed by the VM installs on the hypervisors. The current server ISOs have been used for OS or hypervisor installs. All OS or hypervisor were updated, but otherwise no tweaking was done (e.g. remove snap from Ubuntu).
The tests were carried out manually by starting the (bare metal/virtualized) OS and taking the time until the login prompt appeared. Where necessary, the grub menu was confirmed manually as quickly as possible. Up to three runs were averaged. The host is a HP ProDesk 400 G6 with a i5-10500T CPU, 32GB RAM and a KIOXIA 512GB M.2 NVMe SSD (KXG70ZNV512G). VMs had 2 CPU, 4 GB RAM and 32 GB storage.
Host OS Time to login [BIOS/EUFI in s] bare metal Ubuntu 22.04.4 -/39 Debian 12.5 -/20 XCP-ng 8.2.1 Ubuntu 22.04.4 28/12 Debian 12.5 18/8 Proxmox 8.1.4 Ubuntu 22.04.4 12/15 Debian 12.5 10/10 Even if the differences are measurable, they don't have much significance for me in normal everyday operation. The result is still interesting though.
Edit: Added Time to login for EUFI boot on the hypervisors.

RE: First SMAPIv3 driver is available in preview
@olivierlambert Easy to install and setup on a dedicated host. Did some basic testing with VM creation, snapshots, (re-) import-/exporting, copying, removing and all worked.
The blog post on the SMAPIv3 preview states that it is not yet possible to use this SR type for live storage motion. But it seems that no storage migration is possible at this point (neither live, warm nor cold migration from or to the SMAPIv3 volume). Copying a VM from the SMAPIv3 to a local SMAPIv1 SR works and vice versa.
Looking forward to more capabilities of the SMAPIv3 implementation. Keep up the great work !
Eidt: typos and some clarifications

RE: Settings -> Remote -> (NFS|SMB) on a Sinology NAS
@olivierlambert I think that was probably related to my question if he tried to
connect the same NFS share on the Synology as storage and backup target

RE: Settings -> Remote -> (NFS|SMB) on a Sinology NAS
@aqua-calc said in Settings -> Remote -> (NFS|SMB) on a Sinology NAS:
same NFS is mounted
It is probably dumb to ask: you are not trying to connect the same NFS share on the Synology as storage and backup target?
Edit: did not see your post

RE: Settings -> Remote -> (NFS|SMB) on a Sinology NAS
@aqua-calc What error message do you get when trying to connect the remote to the Synology NFS share? Like others, I am also using a Synology (RS818plus) as a NFS storage and backup target without any issues.
-
RE: Settings -> Remote -> (NFS|SMB) on a Sinology NAS
@aqua-calc Did you check the NFS authorization in the Synology NFS share folders properties (allowed networks)? But that is just guessing and more information or the error message is needed.

RE: NBD error SSL
@andersonvaz said in NBD error SSL:
@gskger This explanation you gave about the Truenas certificate is confusing because Truenas does not have NBD
True, since NBD is the transfer method between the XCP-ng hosts and Xen Orchestra. Sorry for the confusion.
-
RE: NBD error SSL
@andersonvaz I wouldn't call it "using NBD" yet because I'm experimenting with it in my playlab. However, the SSL_CTX_use_certificate:ee key too small error message suggest a TLS cipher problem and since the Xen Orchestra 5.76 blog post states that XO is using TLS by default, so the transfer is secure it might be related. According to that (older) post, you can disable TLS with "insecure NBD" for ruling this out.
But you are right, perhaps others who have more relevant experience with NBD can chime in to help.

RE: NBD error SSL
@andersonvaz All backups go through Xen Orchestra (have a look at the documentation on backups or the excellent YT video How To Use Xen Orchestra and XCP-NG To Backup and Restore Your Virtual Machines by @lawrencesystems.
XO or XOA is the central management tool to visualize, control, backup and manage your XCP-ng hosts and VMs. It must connect to the XCP-ng master host (read/write) to control it. XCP-ng slave hosts are in read only mode, "controlled" by the master hosts settings.
Edit: Backups can also go through Proxies on remote sites.

RE: NBD error SSL
@andersonvaz Sounds a bit like either the host/XO or TrueNAS want's to talk SSL TLSv1.1 which is depriciated. What version of TrueNAS core are you runing? The latest 13.0-U6? Can you check the TLS Cipher settings on TrueNAS (System - General - HTTPS Protocolls)? Which cipher are enabled?
-
RE: NBD error SSL
@andersonvaz Just to double check: Are your running the old FreeNAS (EOL October 2020) or a recent TrueNAS Core or Scale?
-
RE: NBD error SSL
@andersonvaz It probably makes sense to share more information on your setup (type of hosts and storage system, XCP-ng version, Xen Orchestra version, remotes and backup settings).

RE: import of Ubuntu
@bdacasc You need to update the interface name to
eth0
as shown byip a
. -
RE: import of Ubuntu
@bdacasc Are the IPs set static at OS level of the VMs or granted via DHCP?
-
RE: import of Ubuntu
@bdacasc I think @Danp meant it is not recommended to not install the XCP guest tools. So installing the XCP guest tools is recommended an all OS. In that case (guest tools installed) you can keep Realtek as the NIC type, which is the default for the Ubuntu template.

RE: Migration "starts" a VM?
@jessepeterson no host available usually indicates that the destination host has not the required ressources (ram/cpu/SR/ISO SR/passthrough devices/networking/mounted ISO) to start the VM. But the migration process does not actually start a stopped VM, as far as I know.
-
RE: reboot of host does it stop or kill running VM's?
@manilx If the VM has no guest tools installed (like this Windows VM), the host will perfom a hard shutdown of the VM:
So it is a good idea to have the guest tools installed.
