Thanks for your response. I've raised https://bugzilla.proxmox.com/show_bug.cgi?id=6189

Thanks - are you saying that essentially right now this would have to be a new feature, and there's not a recommended way to work around it? Where's the best place to formally request such a feature? Also, would an alternative be for passthrough failures simply mean the backup was tried without...

Is anyone able to help with this please? I've not been able to find anything other than a workaround.

Sorry to bump this, but curious how other people manage this? All I can think is either you simply have to script bringing down all hosts the share a PCI resource before backup (not ideal), or there's some way to script removing the resource as a dependency before and after backup (if it's not...

I got the following error when backing up overnight: ERROR: Backup of VM 114 failed - PCI device '0000:15:00.0' already in use by VMID '107' Now I know why this is - just as it says, the PCI device (a GPU in this case), is already in use. However, I wonder what the recommended solution is? I...

Thanks for this - your solution came near the top searching for "email notifications". I wanted to add to the feedback that this is a bit confusing: 1. It totally surprised me my email provider (Fastmail) even allows this through! SMTP comes up as a Fastmail SMTP, and I had no idea this was...

Sorry to bump this - but any ideas where to start on this one please? I found that eventually this started affecting even the clone. So no idea what's happening specifically with a "restart" of VM from Proxmox host.

I've found that selecting "restart" on a particular Windows 10 VM from Proxmox UI will freeze and restart the whole system. To start with I thought I selected the wrong thing, and restarted the node. However, I've found this is reproducible. The only different log I get from a normal VM restart...

I just found this thread Googling "proxmox create lvs stuck". I see it was started a couple of years ago, but then there's been a few posts, all regarding the N100. I've installed Proxmox dozens of times and never seen this, so I wonder why it's an issue just on some of these N100 mini PCs...

Thanks @dcsapak! Blacklisting worked. Not sure how I missed that Google result - but I see it was from two years ago. I wonder what changed that blacklisting is now necessary, when it wasn't (or didn't appear to be) before?

Thanks @dcsapak I did a complete fresh install straight to 8.2, so I don't have the older kernels. Whatever was latest in 8.1 definitely worked. Right now I have this: Linux pve-maxi 6.8.4-3-pve #1 SMP PREEMPT_DYNAMIC PMX 6.8.4-3 (2024-05-02T11:55Z) x86_64 GNU/Linux I also tried the only...

I'm trying to run a Windows 10 VM clone from a template I've been using absolutely fine. When I passthrough an Nvidia GPU I get these errors in the logs: [Fri May 17 08:31:12 2024] x86/PAT: memtype_reserve failed [mem 0xf800000000-0xf801ffffff], track uncached-minus, req uncached-minus [Fri...

Thanks for your help. Here's the output: lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Address sizes: 48 bits physical, 48 bits virtual Byte Order: Little Endian CPU(s): 32 On-line CPU(s) list: 0-31 Vendor ID...

No definitely not the disk here. Locally copying the same file is way faster.

I just tried the E1000 emulation - although I still see high DPCs, it's not as high as with the virtio driver, and although there's a little jerkiness, it's much more responsive.

I see someone else had the same issue https://forum.proxmox.com/threads/windows-high-dpc-usage.99567/, but unresolved.

Sorry to bring up the old thread, but did you find the solution here? Your post is the top result for "ndis.sys" on here.

Having discovered that DPCs were involved here - it helped a bit with Googling. I thus found a Windows program called latencymon. It reports all green until I run the SMB transfer, and then says there are problems with the "ndis.sys" driver. At 2.5gbit it certainly shouldn't be having problems.

I just tried reducing from 16 to 8 - and I see the same behaviour. To be clear this isn't some very slight latency issue - the whole Windows system becomes jerky and unresponsive at random points during the transfer. Whether it's the hypervisor or Windows I don't know, but it certainly seems to...

Sorry I wasn't clear on the SMB setup. The SMB client is in a Windows 10 VM guest, where the host has a 10gbit connection. I've tried two different SMB servers, both on different physical hardware to the Windows guest I'm seeing this. I perf from the Proxmox host to both the SMB servers show...
