@dinhngtu thanks for advice

i've upgraded varstored and varstored-tools:

rpm -qa | grep varstored
varstored-1.2.0-3.2
varstored-tools-1.2.0-3.2

than i've cleared varstore with secureboot-certs clear
should taht folder contain more files ?

ls /usr/share/varstored/
KEK.uth
PK.auth
db.auth

what about dbx file ?

Xcp-ng version 8.3 (upgraded from Xen 8.0)
Installed all available patches.
Managed by XO community version latest.

Settings for VM:
Boot firmware: uefi
Secure boot: enabled
VTPM: enabled

Hi guys

Windows 11 installation from iso , works ok, installation has done, but after finishing installation and reboot vm stuck on screen with "VM start stuck on "Guest has not initialized the display (yet)."
Cant even enter the uefi setting or boot from iso.
I tried starting with or without mounted iso, tried disable secure boot, but no luck, vm even don' try boot up , screen freezes on that phrase.

The error i see in /var/log/xensource.log :

error||75157 :::80|dispatch:VM.get_secureboot_readiness D:6fb3730d40a6|backtrace] VM.get_secureboot_readiness R:77a097481bb1 failed with exception Forkhelpers.Spawn_internal_error("unserialize_variables: Failed to unserialize variable!\\n", "", _)

Do You have any clues how to handle it ?

it's strange , target exist for sure all other vm's were copied to that sr on new host:

vm.warmMigration

when trying migration i've got only this error in xensource.log on xen 6.5 host:

Server_helpers.exec exception_handler: Got exception INTERNAL_ERROR: [ Not_found ]

when trying to copy vm:

VM export R:8d962d9e711d|dispatcher] Server_helpers.exec exception_handler: Got exception CLIENT_ERROR: [ INTERNAL_ERROR: [ Unix.Unix_error(31, "write", "") ] ]

|xapi] Unhandled Api_errors.Server_error(CLIENT_ERROR, [ INTERNAL_ERROR: [ Unix.Unix_error(31, "write", "") ] ])

i wonder if this error could be connected with fact that this is only of my vms was crated years ago on xen 6.5 with template Windows 7 (than vm was upgraded to windows 10 when it became available) which template is absent on xcp-ng 8.2 (it has only windows 10 templates)
Other vms are windows10 templates and there was no problem to copy them to xcp-ng.

any thoughts on this ?

Thanks for reply.

I tried to use "continous replication" but i got this error:

Hi

Could someone help me with troubleshooting that problem.
I've been trying to move or copy (doesn't matter for me , i really need this vm to be migrated to new host

Old host is xen 6.5 , new one is xcp-ng 8.2
xo-server 5.116.4
xo-web 5.119.1

VM i wish to migrate is one of Windows 10 vm's.

Trying to migrate (option migrate in vm tab) , during process vm is stopped and got this error:

vm.migrate
{
  "vm": "98361714-d7da-ea55-196b-3bad93f23422",
  "mapVifsNetworks": {
    "a5a0ec18-ce3a-bbab-ccc3-788b9b5de01a": "ce58e435-49d3-0fff-6be2-a4f8bc45f39a"
  },
  "migrationNetwork": "e38d287c-238c-830d-ef4a-b57150cb1e16",

}

  "data": {
    "objectId": "98361714-d7da-ea55-196b-3bad93f23422",

  },
  "message": "operation failed",
  "name": "XoError",
  "stack": "XoError: operation failed

    at Api.#callApiMethod (file:///home/node/xen-orchestra/packages/xo-server/src/xo-mixins/api.mjs:417:20)"
}

Another try was to make copy of vm (copy option on vm tab), without compression and what i got is:

vm.copy
{
  "vm": "98361714-d7da-ea55-196b-3bad93f23422",
  "sr": "ee68ade2-858d-efe1-d4af-60bf2075adba",
  "name": "Windows 10 (administracja)_COPY"
}
{
  "message": "no opaque ref found",
  "name": "Error",
  "stack": "Error: no opaque ref found
    at extractOpaqueRef (/home/node/xen-orchestra/@xen-orchestra/xapi/_extractOpaqueRef.js:8:19)
    at processTicksAndRejections (node:internal/process/task_queues:95:5)
    at Xapi._importVm (file:///home/node/xen-orchestra/packages/xo-server/src/xapi/index.mjs:676:19)
    at Xapi.remoteCopyVm (file:///home/node/xen-orchestra/packages/xo-server/src/xapi/index.mjs:375:50)
    at Xo.copy (file:///home/node/xen-orchestra/packages/xo-server/src/api/vm.mjs:841:7)
    at Api.#callApiMethod (file:///home/node/xen-orchestra/packages/xo-server/src/xo-mixins/api.mjs:417:20)"
}

I checked if vm has dynamic min/max and static memory same values.
There is no any iso mounted to that host.

It's strange because all of others Windows vm's , had no troubles with copying them to new host.

Could some one narrow me what else to check , what log to observe ?

@danp Thanks for advice , that works.

Hi

I've done installation on Ubuntu 20.04.2. LTS according to this official tutorial:
https://xen-orchestra.com/docs/from_the_sources.html

but there is something wrong, there is no

~/xen-orchestra/packages/xo-server/bin

I'm able to run XO only by starting it with command

yarn start

but there is no directory bin with modules to run this server by systemctl.

I did exactly like tutorial says .

Regards
