Is it normal that the id changed from the host to the VM? As far as I can remember (which can be wrong), in my previous install, the ids kept the same number but now theyr are totally different. I am asking that because I can't successfully install NVIDIA driver either from .run or APT cause I...

I am not sure I fully grasp what is proper IOMMU isolation. iommugroup =1 device_name=GP107GL [Quadro P600] seems OK iommugroup=14 device_name=SAA7164 [Hauppauge tuner] seems OK iommugroup=15 device_name=Coral Edge TPU seems OK iommugroup=1...

Damn, I just started of fresh install of Proxmox 8 while I was previously on 7. Is it still true in Feb 2024 that its best to have docker in VM instead of LXC ?

ok.. the host has 16GB VM1 has 8GB allowed VM2 has 3GB allowed Apart from updating Proxmox from 7.x to 8.x, nothing changed in the VM.... A recover of the VMs to when it failed should bring it back to normal. Should I investigate more? If yes how? Or should I simply fresh install PM 8?

The Debian-VM works until I restore HomeAssistant, then Debian stops booting. I am confused.

the VM.conf asks for q35 and somehow, at restore, it reverted to i440x. Can it be that the host is now un Debian 12 and the VM at debian 11 ?

I dont' know how this is possible but in order to get passthrough, machine type is supposed to be 135, which it was. And not it's q440x... How is this possible?

this seems ok root@pve1:/etc/modprobe.d# cat /etc/kernel/cmdline root=ZFS=rpool/ROOT/pve-1 boot=zfs quiet intel_iommu=on iommu=pt pcie_acs_override=downstreem,multifunction nofb nomodeset video=vesafb:off,efifb:off intremap=no_x2apic_optout

I checked this on Proxmox host root@pve1:~# lspci -nn 00:00.0 Host bridge [0600]: Intel Corporation Xeon E3-1200 v3 Processor DRAM Controller [8086:0c08] (rev 06) 00:01.0 PCI bridge [0604]: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor PCI Express x16 Controller [8086:0c01] (rev 06)...

earlier this week, I upgraded the host from 7.x to 8.x It worked fine. If I remove the Quadro and Tuner card from "pcie hardware" in the VM, it boots. If I want to add them back, there is no mapped devices. So something in the host has messed with the passthrough. Anyhelp to investigate this ?

Yesterday, I switched from PVE internal backup to PBS. I don't see how it's relevant but my VM stopped working on the same night. All of them. I retrieved a 2-day earlier backup from PVE (not PBS) to no avail. It won't start journalctl on pastebin

Found it. Solved for my debian VM But, do I understand that I made the mistake of creating a VM on an NFS-Share normally used for backup purposes ?

I moved from internal Backup to PBS. When internal, I had an NFS share With PBS I have a PBS store. I made a first snapshot, verified that the recover worked... and then, deleted the old backup tasks to the share and deleted the volume Big mistake. All my VMs won't start because of the...

Am I missing something because: even if root@pbs:~# cd /mnt/pbs_core root@pbs:/mnt/pbs_core# ls -la total 12014 drwxrwxrwx 3 nobody nogroup 4 Jan 30 21:40 . drwxr-xr-x 3 root root 4096 Jan 30 21:37 .. drwxr-x--- 65538 backup backup 65538 Jan 30 21:42 .chunks -rw-r--r-- 1...

How? Did you change that using ACL or from within Sharing, NFS, Edit ?

The problem with this solution is that QNAP allows one to changer userID and groupe. One cannot do that on TrueNAS core... Do you think of a workaround ?

For me, it is not working because the directory and share are made by user=root while the datastore creation is made by user "backup" root@pbs:/mnt# proxmox-backup-manager datastore create store_core /mnt/store_core TASK ERROR: EPERM: Operation not permitted Error: task failed (status EPERM...

ahahaha THANKS no, not except for that. That's exactly what I needed. Either I did not read thorouhly or, I would have benefited from a "comparison table" that I did not find but I fully get the benefits you listed. I would add it's not that I did not find what was offered by PBS but rather...

I read the documentation and cannot get why I would need PBS over just running backup jobs from : PVE\Datacenter\Backup ? I'd like some explainer on the limitations of the later ? Thanks

Thanks, that's my mistake.
