GGorgonzolaPrimavera replied to the thread Container creation stopped allowing Ceph RBD storage.So if the `krbd` option is there to force use of the kernel module, that implies that there is a userland interface to the RBD. Is that correct? I'm also assuming that this forces the *host* to use the kernel module for a VM's block requests...

The issue is almost certainly that KRBD (Kernel RBD) is disabled on your vms storage configuration. Why VMs work, but LXCs don't VMs access Ceph directly in userspace via QEMU (librbd). LXCs share the host kernel and need the host to map the... -

The KRBD setting in the storage config only affects how VMs access their virtual disks on RBD. For CTs it will always be the kernel variant where rbdmap is run, to map an RBD image to a local block dev.

Vverishare posted the thread Optimizing Windows VM performance on older hardware - settings advice needed in Proxmox VE: Installation and configuration.Hi everyone, I'm looking for advice on the best Proxmox settings to get a Windows VM running smoothly on my setup. Host specs: CPU: Intel Core i5-3570 @ 3.40GHz (4 cores, 1 socket) RAM: 32GB Storage: SSD + HDD GPU: AMD Radeon HD 7470/8470...

Kkfietz replied to the thread Windows Server 2025 CPU suddenly at 100%.As it even fails to start fresh on this "problem" node, then maybe the check for hv-evmcs is forced, even tho it is not used by the cpu type later on? Maybe it is added by defining the os type as windows? Is it listed under cpu features in -cpu...

MMeister Mopper replied to the thread Testing Fix / Prevention: pve-ha-manager deadlock during apt dist-upgrade (Automated Script).Hi @fabian, I checked `/var/log/syslog*` using `zgrep` for July 16th, but unfortunately, those syslog files have also already been rotated out and deleted due to the log retention settings on this node. Please let me know if there are any other...

JThere are some myths around SLOG, L2ARC and special device(s) in ZFS which always re-appear. 1) SLOG A SLOG is a separate storage for the ZFS Intent Log (ZIL). Synchronous writes are protocolized and written back in the ZFS pool later. For...

JYou say that you're using LVM-Thin, so I'm assuming you're using a hardware RAID? Then you'd need to check what your hardware RAID controller is capable of and whether it can add an explicit cache. If you can or want to use ZFS, is there an...

SteveITS replied to the thread Windows Server 2025 CPU suddenly at 100%.Indeed, nested is not enabled on the "problem" node. CPU flags are the same. Leaving two questions I think: 1) should PVE/QEMU fail this VM startup if nested is disabled, or just ignore that and proceed? (it's saying to use a flag that it... -

Rreshma replied to the thread PVE 9.1.11: HA CRM stuck in wait_for_quorum despite corosync quorum OK.yes I have removed the nodes from HA as I couldn't add 3rd node and that is when I'm not able to bring back nodes to HA. But Thanks, it worked now when I added the VM's from all the nodes to HA resources and then it worked. I could see all 3...

DHi, is the device not present on the system anymore? Can you try with the Cleanup Disks checkbox disabled? Then it shouldn't try to access the disk and just remove the systemd mount unit.

JJohannes S replied to the thread ProxmoxVE and the shared root account for update/upgrades..There is also an answer and review of @gyptazy patch by @t.lamprecht which basically mirrors the reasoning from tge ticket against providing such a feature due to security concerns.

There have also been patches supplied to get this into the API, which is from I understand the main problem right now: https://lists.proxmox.com/pipermail/pve-devel/2025-September/075183.html

Normally you can import them, that said, they might have been built with VMXNET3 and pvscsi so you will have to tackle that.
