Hi Promoxer, You can backup individual disks in the GUI and restore them individually if I'm not mistaken. Then you detach from the guest that's broken and attach to a guest that you prefer. Some of this functionality is improving in the GUI (there are feature requests being actively worked on...

We've also been in communication with ML SIEM makers that talk about port mirroring and rules they would generate in PVE to stop malicious attacks from things like Ransomware. Again this could be costly on the host CPU to process those restrictions and port mirroring. I think the best solution...

Just an update on this, I've gotten it to work but it's not stable on Apple Silicon- it frequently crashes, clipboard is sometimes unidirectional (VM->Client), Window Resizing doesn't work sometimes, etc. However, performance is quite good. Client brew tap jeffreywildman/homebrew-virt-manager...

Huh, I never considered that. Great point! Currently, all the VM disks I exclude are too big for backups (~5TB) and live on "safe" (replicated) storage, never occurred to me that you might want some disks more frequently backed up than others. +1 to this.

Hi everyone, I know this exists for virtual machines now (including RW distinction, IOPS, and burst) but is there an upcoming solution for Linux Containers (LXC / pct) or a solution available in the command line? Yes, I know the fact that it's a mount point on the FS makes it really...

Hey Spirit, I'm pretty sure if you did it yourself you'd install Ubuntu (supported OS) on the DPU and then modify PVE to send all of the networking rules for that card directly to the Ubuntu OS. In the case where it become supported by PVE it could look like: Create a bridge in the PVE GUI? PVE...

Hi Spirit, Keep in mind some DPUs include the ability to run the entire hypervisor or a specialized sub-OS on them. Meaning you can run RouterOS directly on a Mikrotik DPU or Ubuntu with iptables on an NVidia Bluefield card. So the options for PVE seem endless, not just for standards that...

Given that EXT4 is the default and most supported file system for Linux servers, is this something PVE can talk "shop" with the kernel devs about? Thanks, Fiona! I'd do it myself but I feel hopelessly unwise about how to communicate the issue upstream. Tmanok

Hi PVE Devs, For the last three years, I've kept a keen eye on new high performance computing hardware and modern virtualization techniques. In recent years, previously inaccessible technologies such as DPUs have become more readily available, enabling even medium size businesses to acquire...

Hi Falco! Pardon my delay. Ok there are a few things that are big warning flags to me, but I agree with a few of your thoughts as well. In order, my responses are: Thank you for the CPU model. That is a good CPU, despite the slower clock speed, it is fairly ideal for virtualization. 2x...

Hmm, something seems off with this. What model of CPU? How much memory does PBS and PVE have? (How much is used on both) How is the NIC bonded? LACP? Round Robin? etc.. If you run iperf3 from your PBS host to your PVE hosts, what is the average throughput? (>~18000Mbps is acceptable given a...

Hi Everyone, Wondering whether or not Virtio SCSI Single supports TRIM in guests, I have observed it not working automatically during disk migration with a hook script but when the disk controller is set to Virtio SCSI, it works as expected with no other changes. Evidently, I've prefer to use...

OP said they have XFS. But yes, you're right I forgot that PVE replicates block storages only. Drat, you were right Neobin! Tmanok

This is part of why you should have more CEPH nodes than total number of replicas. The same minimum PVE configuration regardless of storage is 4 nodes. With four nodes, you can maintain 1 (turn off), lose another to failure, and still have 50% workload. The non production or non HA (non...

Hi there, I believe you will be fine. But you may need to remove the failed device manually later. Normally, you would offline the pool but seeing as this is the OS I think you might have made the right call. Comprehensive doc...

Not directly related, but what is hosting the SMB? Tmanok

I think what the OP means is that the backups are not application aware. This is an issue I've brought up to the PVE devs before. The guidance for MS SQL and other large databases is to create a dump (transaction log and db dump) which will force the database to create one or more files...

Hey Noel, You'll need to provide more detail. Also make sure you are using root and the PAM realm in case you switched it. Have you tried logging in from console and rebooting? Tmanok

Thanks for sharing, BBGeek! Always good to read your posts. Tmanok

Do you use ZFS as Neobin is asking? Assume Windows VMs will use "all" RAM because they cache heavily and Ubuntu may be using most of it for the same reason. You can use HTOP on PVE and press F6 to sort by memory usage. HTOP will also quickly show three memory colors. 1. Green is allocated...
