    Windows suddenly believes it's NOT a VM

    Do not use "host" CPU type in your VM. You can try "max" if no Live migration used. Or model close your physical host CPU.

    args: -cpu host,-hypervisor No longer boot since Windows Update 01-2026 ( KB5073723 KB5073457 KB5074109 KB5073379 ) AMD EPYC 7302p

    Doesn't boot either with EPYC-Rome-v4,-hypervisor where EPYC-Rome-v4 alone works. Works with args: -cpu EPYC,-hypervisor Waiting the next month if Microsoft fixes the fix, like the Stop Code UNSUPPORTED_PROCESSOR BSOD.

    Try your SQL under Lvmthin during a week, to exclude ZFS or not. CDM benchmark show Fujitsu on ESXi is slower than Dell on PVE.

    Seems I'm encountering a bug. Host CPU is AMD 7302P ( EPYC Zen2 "Rome" ) on HPE DL325 G10.

    Abysmally slow restore from backup

    Just to report : even local restore is boosted. PBS alongside PVE , Restore to Datacenter SATA SSD from Datacenter SATA SSD 170G used data of 400G virtual disk Speeds are over SATA speeds because writing zeroes seems accounted/ PVE 8.4.0 restore was 630MB/s ( ~11 minutes) ( so real speed was...

    PBS sync not 1:1?

    GC job must be set on each PBS. Prune should be set on each PBS, Snapshot sync deletions called "Remove vanished" isn't safe from my point of view. See : https://forum.proxmox.com/threads/garbage-collection-on-synced-targets-necessary-if-remove-vanished-is-checked-eom.158266/

    Proxmox VE improper interfaces naming

    another way, with nowadays systemd versions, shipped with pve 9 , is to use MAC based altname, like enx123456789012 where 123456789012 is the MAC address.

    Support for SQL Server 2019 & 2022?

    just to clarify, MDF files as SQL backups by PVE/PBS are valid, because rely on SQL VSS agent within Windows guest. Only granular restore is missing. Full MDF need to be downloaded/restored, attached as temporary to recovery specific DB.

    API token permission for "datastorebackup" does not allow creation of backup, only user permission "datastorebackup" works - why?

    edit : myself test with a PBS v3. 2 grant user permission is required to allow API token Read Datastore for Sync job. (perhaps fixed in newer version) https://pbs.proxmox.com/docs/user-management.html#api-tokens

    Support for SQL Server 2019 & 2022?

    no, if compression not used. As PBS deduplication does not rewrite existing data.

    Why i cant install WinSever 2012 R2 its keep let me install again and again

    it should work, but as you have a problem, the idea is to do a new install in BIOS.

    Why i cant install WinSever 2012 R2 its keep let me install again and again

    once Legacy BIOS selected, don't forget to set Boot order too. VirtIO v285 does not support 2012 r2, use older version like v173.

    [SOLVED] Extremely low speeds when backuping

    Run tailscale status and examine the connection information for the peer device. If the output contains "direct", the connection is direct. If the output includes "relay", the connection is relayed through a DERP server. If the output includes "peer-relay", the connection is relayed through a...

    no, changing FS ( zfs / Lvmthin / btrfs) implies formatting.

    Proxmox VE 9.1.1 – Windows Server / SQL Server issues

    ZFS is slower than vmware FS (as it does raid, checksum integrity...) . Try with Lvmthin
