We run VM's on multiple servers with different hardware. Customers with their own servers have the same issue. In our own cluster, we use Intel Xeon and AMD Epyc CPU's. Both have the same issues.

Ok I'm 100% sure we can't fix this within Windows. I even tried to replace the OS disk with another (working) VM OS disk and boot. It wouldn't boot... Even with the Windows Server 2012R2, 2016, 2019 and 2022 installation ISO's it won't boot. It will only boot to other ISO's, like HirensBootCD...

I tried a few things within the Windows VM, but it doesn't fix anything. Even when I do a hard reset in Proxmox, skipping the update on shutdown and startup, the VM won't boot.

Also an important note: I can rollback the VM and get the issue over and over. But if I stop the VM (stop the KVM process) and start the VM (fresh start) it doesn't happen again, even if I rollback to the snapshot when I was able to reproduce the issue. So it has something to do with the...

I can reproduce this issue on my own cluster. I have a RMM tool that helps me to locate affected servers. When I search for all Windows servers with 30+ days uptime and "reboot required" (due to installed updates) -> it always fails to reboot correctly. If I snapshot a VM and rollback, I can...

We solved it by exporting the zdb information to a text file and filter out to only have this type of content: 5a0000 0:5e0867ba000:1bc00 5c0000 0:5dbcb34b400:1e000 5e0000 0:5d8a6580a00:14400 600000 0:674edfe3a00:14400 620000 0:5dba3caa600:19800 640000 0:5d964d0ea00:18c00 660000...

We found the disk with zdb, by specifying the object: zdb -ddddd hdd/test 384 | more Object 384, 12k, 296GB real size, 500 GB disk size, 128k blk size, 512 dnsize This is the file we are missing. We are trying to recover it now, but it's hard to find any information on this.

We create ZFS snapshots and replicate them to 2 different systemens, with a retention of 6 months. Since the running disk was removed 8 months ago, we don't see the disk as a file anymore. We do see data change in the ZFS snapshots, so there is some data but it is not visible to us. This is also...

Hi, I managed to delete a VM disk a long time ago, while it was still running. Now, 8 months later, I stopped and tried to start a VM but it won't start because the disk is missing. 8 months ago I did a move: create full clone of drive virtio0 (ssd:100/vm-100-disk-0.qcow2) Formatting...

Hi, We have a small cluster with 3 nodes and 2 storage servers. The nodes are connected with a bond to 2 switches with LACP. Switches are in virtual chassis and have the port groups configured. Recently we started to see network errors/hickups. They only seem to apply on the proxmox servers...

Hi, This function doesn't work (yet). You have to move the disks offline with rsync and bwlimit for example.

The bwlimit: function in datacenter.cfg doesn't work. You can only copy disks with rsync bwlimit when the VM is stopped. See other forum posts, moving disks with limits in datacenter.cfg doesn't work. It will just use the full MBps possible.

On the hosted Windows Server OS, navigate to Network Connections, open Ethernet Adapter properties and disable RSC for both IPv4 and iPv6 Once you have manually disabled RSC on the network adapter, you must restart the machine for the changes to take effect.

We solved our problem. We used stable virtio drivers (not latest) and we disable RSC on ipv4 and ipv6 on the virtio adapters.

Tested this on a different cluster, installed 2 weeks ago. Same problem, it doesn't listen to the datacenter.cfg settings

Hi, I've logged out many times and used different computers / complete browser refresh / private navigation. There is no configuration in the /etc/pve/storage.cfg other than normal: nfs: zfs01 export /data/proxmox path /mnt/pve/zfs01 server 10.1.1.81 content...

Hi, I've put different options in /etc/pve/datacenter.cfg but it doesn't seem to apply. For example, I put language: de and reload the webinterface or use private navigation, but it's still English. Also, I've put bwlimit: move=2,default=2,migration=2 in the file but still it keeps taking...

Hi, We use E1000 because Virtio has a lot of bugs (really slow). I will disable the hardware checksum offload and reboot the PfSense, see if it helps.

Hi, We have a 6-node Proxmox cluster. Recently we updates from Proxmox 4 / Debian 8 to Proxmox 5 / Debian 9. Since the upgrade, we have many failed PfSense firewalls running as VM on Proxmox. We run every PfSense firewall with 2 adapters. 1 adapter is for WAN without a VLAN, the other adapter...
