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...

Sorry - I ought to know better! Here's the guest config: agent: 1 balloon: 0 bios: ovmf boot: order=scsi0;net0 cores: 16 cpu: host efidisk0: local-lvm:vm-110-disk-0,efitype=4m,pre-enrolled-keys=1,size=4M hostpci0: 0000:01:00,pcie=1,rombar=0,x-vga=1 hostpci1: 0000:15:00.0,pcie=1,rombar=0...

Quick update to this - while running the SMB copy, I see "Hardware Interrupts and DPCs" go from 0 to 8% (total) CPU, which seems to account for the CPU core being pegged. Wondering if that's something to do with QEMU or a native Windows 10 problem.

I have a strange Windows 10 guest issue. I don’t have any native Windows systems to just try it. When I copy a 20GB file over SMB, Windows 10 stutters - not just the mouse pointer, but animations in a running browser (for instance). I tried copying the file locally, while also running iPerf...

It seems odd to be forced to move root and swap off the “PVE” VG, just to be able to have “local-lvm” on a different SSD. So I’d be trading one quirk for another. What’s the recommended way of doing this? I can’t believe I’m the only one that would want the Proxmox root on its own disk, but...
