A stock Proxmox VM leaks SMBIOS UUID, serial, MAC OUI, and the hypervisor CPUID bit. Here's exactly which ones qm set can change and which you can't touch.
Metasploitable2 runs fine on Proxmox if you import the VMDK with qm importdisk and set the network to NAT. Here's the exact procedure.
Proxmox VM unreachable after new install? Use ip and bridge commands to isolate host, bridge, or guest layer. Here's the sequence that finds it.
How to download files from Proxmox node depends on what you mean: a file inside an LXC, a VM disk image, or a backup.
Your qcow2 file is bigger than the configured disk because of preallocation, snapshots, or metadata.
Backup LXC to NAS NFS share fails with permission denied? The fix is root squash and NFS version. Here's the TrueNAS and Proxmox config that works.
No built-in export button, but pvesh gives you the summary in JSON. Pipe it through jq to get a clean CSV for any host or the whole datacenter.
That Proxmox warning means one of three things: no agent package in the guest, no virtio-serial channel, or the Agent option is off.
QEMU Guest Agent RAM reporting is block-level, not usage-level. Here's what guest commands return and what you need to get real memory stats.
Live migrations get slower over time because the VM keeps dirtying memory faster than the network can send it. Here's how to measure it and fix it.
