no snapshot with Win11 VM TPM 2.0 activated ?

[nsc]

Hello,

I have installed a Windows 11 VM with TPM 2.0 active on the latest proxmox version :

Everything is OK except that I can't do a snapshot : The current guest configuration does not support taking new snapshots

I did the same test with a Windows 2022, same result.

Can we create the .raw file TMP state in .qcow2 format?

I guess that's the reason for the problem.

Thanks

Hi,

Can we create the .raw file TMP state in .qcow2 format?

No. However, you can move the TMP to another storage [0] who supports snapshotting raw volumes.

Hi Moayad,

Thanks for your help, it's working now.

What i did :

- backup my labs VM in vma.zst format with GUI
- download my backups locally
- reinstall proxmox (my lab is on dediacated ovh server)
- create a ZFS pool with RAID5
- create a ZFS dataset in the pool (get info from this topic : https://forum.proxmox.com/threads/can-we-use-zfs-storage-as-backup-storage.100631/ )
- configure backup dir in /etc/pve/storage.cfg (still from topic)
- upload my backups files into the directory
- restore backup with GUI
- start VM Windows 2011 / 2022 with TPM 2.0
- take a snapshot
- modify data into the VM
- rollback snapshot

very impressed by the simplicity, the only complex thing was how to create a backup directory in the ZFS pool...

 

[Moayad]

Hi,

You can create a file into your ZFS storage (mkdir /rpool/backup) and add the directory file as a backup storage in your Proxmox VE by going to Datacenter -> Storage -> Add -> Directory, then you have to give the path of the backup folder you created earlier.

This is what i tried first but this doesn't work, directory was unavailable and inactive :

Hi,

Thank you for the output of pvesm status!

Did you edit the storage.cfg file manually?

Can you please post the output of cat /etc/pve/storage.cfg command?

 

[nsc]

i just did this :

zfs create zp-raid5/backup

And update storage.cfg

root@nsXXXXXXXXXX:~# cat /etc/pve/storage.cfg
dir: local
        path /var/lib/vz
        content iso,snippets,vztmpl
        prune-backups keep-all=1

zfspool: zp-raid5
        pool zp-raid5
        content iso,backup,rootdir,images,snippets,vztmpl
        mountpoint /zp-raid5
        nodes nsXXXXXXXXXX

dir: backup-local
        path /zp-raid5/backup
        content backup
        is_mountpoint yes
        prune-backups keep-all=1
        shared 0

i tried to create with "mkdir /zp-raid5/backup" first but that didn't work.

Hello,

Can you edit the /etc/pve/storage.cfg file and get rid of the dir section and try to create the directory from the PVE Web UI or from pvesh tool as the following:

pvesh create /storage --storage backup-local --path /ZFS/test --content backup --type  dir

 

[nsc]

i can't create a directory in web UI, alls the fieds are "red" :

 

[Moayad]

Hi,

You have to create the Directory on the datacenter level, i.e., you have to go to PVE Web UI -> Datacenter -> Storage then click on Add then Directory.
