Hi, I've seen that this question comes up in the forums once in a while, people wondering why menory usage in VMs is reported in the Proxmox VE view as over 90% when within the VM the memory usage is reported much lower. Unused memory is waste so many VM operating systems and configurations...

Hi all, This is probably very easy for any regular networking engineer, but I'm stumped. I am trying to set up a pve host on vlan 2 and I want to be able to configure VMs/CTs to be on any of the available VLANs. I'm just not getting it to work. I've set everything up as I think it should be...

Hi, This may be an unusual scenario, but I've installed pve under a Hyper-V host on my laptop so I can try out things when on the move. I'm having a problem that is probably mostly a Hyper-V issue, but when my laptop goes to sleep, my Proxmox guest starts up. I would like it to sleep (save...

Hi, I was just wondering if there is a specific reason why the change suggested in ticket 2534 has not been implemented. I'm probably missing something, but as I understand from reading the ticket, it would be a simple 3 line diff change to fix an issue when the agent is supposed to be running...

Hi, I am experimenting with cephadm and I've done a couple of proof-of-concept installations. For this issue, I have a new proxmox installation and I have installed and bootstrapped cephadm. Proxmox is running fine and ceph is running fine on the same hardware. I have tried to add a ceph rbd...

I have a proxmox installation running sophos UTM using pci(e) passthrough for one of the two nics, the other nic is connected to vmbr0 and connected that way to the vm. It works without a problem and I can prevent proxmox from being exposed directly to the external network. I wanted to try...

Hi, It's probably something obvious but I'm stuck. I have a node with a pcie device available for passthrough (a sas adapter). The device has been attached to one vm, and I wanted to attach it to another vm instead. VM602 is switched off, the device is removed from the hardware configuration...

Hi, I am trying to run fio [1] in a windows server 2019 guest with the redhat virtio scsi pass-through driver. As soon as I run fio.exe it crashes and the event logger says this: Windows cannot access the file for one of the following reasons: there is a problem with the network connection...

Hi, I'm having an annoying problem with a 5 node cluster. All OSDs are crashing on one node just after midnight most nights. In syslog I can see that starting at 23:58:53 all the osds on the node start having issues with heartbeat_check with no reply from other osds. A minute later all the...

Hi, I am installing a Dell R720x with an X540 NIC. This card has two 10GB and 2 1GB, however they are all just working at 1GB. When I connect the card to a 10GB switch it negotiates 1GB only. I can't see any relevant issues in dmesg and I don't know if there is a way to disable/enable 10GB...

Hi, I have unsuccessfully been searching the qemu and proxmox documentation to find a way to allow a guest to use a nic without allowing access to the host. Is this possible? Would it be possible with PCI passthrough? Thanks

I have a PVE project where I am installing 6.0 on a HP Microserver Gen8. Unfortunately this machine can only boot from the first HDD (in AHCI mode) and I would like to keep the big drives for storage (ceph). Additionally, the server does not have have UEFI and can only boot from the USB 2.0...

I am having problems configuring ceph within pve. The blocker for me is that, as I have obviously made a mistake with the configuration somewhere, I am not able to purge and restart. In other words, I have a forked ceph installation on my newly installed 6.0 node. These are the things I have...

Hi, I am testing the new version of PVE together with ceph and I am having some problems. These are my steps: 1. Burn 5.4 release 1 iso with Etcher 2. Install on SSD (USB) with ext4 3. Disable enterprise repo, enable no-sub repo, run dist-upgrade 4. Run wipefs -a on all ceph drives 5. install...
