    Remote migration of cold VM - EERROR: no export formats for 'VM-pool:vm-9999-disk-0' - check storage plugin support!

    My two cents: Running 2 Clusters on 7.4-18, identical hardware, storage ceph on both; online migration works (as far as tested), offline migration gives "no export formats for 'Storage". we are doing offline migration using a pipe: vzdump "$vmid" --compress 0 --mode stop --stdout |ssh...

    [SOLVED] Permission Role that allows backups but denies restores ?

    Hello, Fearing ransomware attacks, I am searching for a role that allows backups but denies restores or deleting of backups – such a role does not seem to exist. It would be fine to use: DatastoreBackup "Can backup and restore owned backups" and change the owner to another API token...

    freezing of virtual Windows Clients on boot

    We have that in two different organizations of our group, server2019 and server 2022 affected, problem also in the newest PVE version. We think it might have to do with windows fast boot (because a reboot does not fix it but a poweroff / start does). We are in the task of switching fast boot...

    freezing of virtual Windows Clients on boot

    Same here. Windows server 2019,2022 and win10 VMs show the "spinning icon" (non-spinning here) after the reboot that follows a windows update. Rebooting restores exactly this state. machine must be stopped and will boot fine right after the next start. we are on a fairly new pve version.

Every first try always ends in a timeout no...

    [SOLVED] Restore speed slow ?

    Thank you very much for the suggestion, much appreciated. We will evaluate such a setup and compare it to a 1st level / 2nd level setup where the 1st level is pure ssd but much smaller and thus holding just a minimum of backups.

    [SOLVED] Restore speed slow ?

    hello, For backup storage, we are using a software raid from 10 hdd, not ssd configured into zfs raidz2-0 using the gui. We see 160 MBps restore speed in the logs. As we have some multi-TB Servers to restore, i would like to ask if that can be optimized. Proxmox Virtual Environment 7.1-10...
