@Forza From GRUB screen, you can press c to enter command line mode then type fwsetup to enter UEFI settings.

@BSmithITGuy Thanks for your information. The temporary workaround now is put Xen Orchestra to the same XCP-ng management network.

Update 1: Diving deeper, I discovered that the API was changed the host management address (where the VM is located) to the backup address:
https://github.com/vatesfr/xen-orchestra/blob/92932dd54645838db58ecfdd872895c5ad461608/packages/xen-api/index.mjs#L1010

async _setHostAddressInUrl(url, host) {
...
url.hostname = await this._getHostBackupAddress(host)
}

It also happens when you run xo-server as non-root user.
